January 2023 update

Dear Friends of CinemaTechnic:

Perhaps you have noticed things have been very quiet around here. I have been in stealth mode since February 2022 when I made a major career pivot to the high tech industry and relocated to the San Fransisco Bay Area. I am now working in machine vision as part of a manufacturing engineering team.

As many of you know, I have been servicing and upgrading professional motion picture film cameras as a technician for a long time – over 20 years. In that time I have gathered a lot of hard to find documentation, spare parts and special tools for ARRI and Moviecam cameras.

I no longer have the bandwidth to support film cameras, or the space to do the work. I want these rare items to go to persons that will use them or at the very least appreciate them. I will be listing these items over the next several weeks. I don’t have much left so act fast.

We’re back! You may have noticed this site seemed to disappear for a while. This was a result of incorrect DNS settings. Regrettably this happened during an extremely busy time for me and I was not able to correct the problem until recently.

There was also a problem with some malicious code that got introduced somewhere on our server. This re-directed links from popular search engines. This issue has also been resolved.

At the end of November 2021 CinemaTechnic relocated out of the Pepperell Mill Campus in Biddeford, Maine. The campus been sold to an investment group.

Please note that at the moment CinemaTechnic is an online-only remote-only business. We currently have no brick-and-mortar presence. Our old addresses: Biddeford, ME 04005, Burbank, CA 91506 and Los Angeles (Hollywood), CA 90028 are no longer valid. Many search engines are still showing the old addresses.

At this time I am not accepting cine lens or camera service jobs. Consulting and Cine Lens Service Training are still available.

I am in talks regarding some exciting new opportunities, which I cannot disclose at this time.

You can still contact me via the email address listed below.

Bring your richter collimator into the 21st century

CinemaTechnic M-2 Digital Focal Plane Micrometer with IMS Adapter and ARRI PL Mount

CinemaTechnic continues to introduce new upgrades that bring the vintage Richter Cine collimator system up to todays standards of accuracy, and improve ease of use. Our upgraded Richter systems can compete with collimator systems costing up to $38,000.- at a fraction of that cost.

Our new R-2 Digital HD Video Output conversion for the Richter R-2 Collimator Block is just out of prototype stage and the first system has been delivered.

R-2 Collimator Block with Video Relay and HD camera, example of actual HD video image

This compact system uses high resolution optics to relay the collimator image to a compact single sensor HD camera. Image quality is excellent, far superior than the original shop-made eyepiece. We are currently accepting reservations for this upgrade. Production will be limited.

Richter Collimator 1080P HD
CinemaTechnic Richter R-2 Collimator 1080P video output

Our system is compatible with cameras up to 2/3″ sensor cameras. With an inexpensive and compact 1/2.5″ sensor camera, you can get a 1080P output of the collimator image that fills the screen top-bottom.

The photo above shows the collimator image on a small monitor. The image was captured at 8.7x magnification (a high resolution 15mm prime lens tested with a 130mm collimator objective). It shows a typical image quality of the collimator output when testing a very sharp lens.

Our M-2 Digital Micrometer upgrade for the Richter M-2 Focal Plane Micrometer is also available. The M-2 Digital is a highly recommended upgrade that improves both accuracy and ease of use. Several of these upgrades have been delivered since we introduced it in January 2019.

Our IMS Richter Adapter upgrade allows the use of industry standard IMS (Interchangeable Mount System) lens mounts. This allows quick mount swaps without having to individually calibrate flange focal distance for each mount.

Since our system threads on to the Richter M-2, it is possible to remove it when you need to test a mount that has an FFD too short for IMS (such as Sony E), then quickly re-install the IMS Richter Adapter.

First deliveries of our new Flange Focal Depth Gage kit are about to be made.

Future planned upgrades:

  • “On Board” LED Illuminator (variable intensity)
  • New collimator objectives
  • Internal upgrades for the R-2 Collimator Block
  • All New Collimator Bench

Please get in touch via email for availability and pricing for these items:

All CinemaTechnic products are Made in USA using components sourced from suppliers in US, EU, Japan and S. Korea. We expect that our products will continue to be available despite the current pandemic.

At the moment, we are still operating as usual. You can check here for updates.

HD Video output for Richter Collimator

CinemaTechnic is pleased to announce our Video Upgrade for the Richter R-2 Collimators. The photo above shows the prototype unit during testing. The first production unit has been sold.

The Problem

One of the most frequent requests we get from customers of our Richter Cine collimator upgrades is for a better eyepiece. Until now, Richter collimator users needed to bend down and push their eye sockets uncomfortably against a small rigid plastic eyepiece in order to see the image. The quality of the magnified image was poor.

Unfortunately, the design of the Richter R-2 complicates finding a replacement eyepiece. The R-2 requires a very compact and high power eyepiece.

Our Solution

We replace the original eyepiece with a modern achromatic eyepiece design. The new eyepiece has modern multi-coated optics. We modify the R-2 collimator block to accommodate a custom housing that allows the new eyepiece to be used.

The new eyepiece is superior to the original in every respect except magnification, which is slightly lower. It has higher resolution, a wider field of view and much better eye relief. Even without the HD video relay, it is easier to see the collimator image with this eyepiece.

When coupled with our high-resolution video relay lens, the Richter collimator image is highly magnified without loss of image quality. It can be comfortably viewed on a monitor.

Camera Compatibility

Our optics are compatible with up to 2/3” single chip C-Mount cameras, up to 3k horizontal resolution. We recommend 1080P or 2k cameras as having enough resolution for the collimator image. With a 1080P HD 1/2.5” chip camera (as seen above) the image of the reticle fills the screen.

Calibrating back focus on Cine Lenses is much easier when you can view the image on a monitor. This is particularly important with Vintage Cine Lenses which are not very sharp, and with Anamorphic Lenses.

Being able to see the image and the focus scale or micrometer reading at the same time allows you to see the relationship between the two in real time. This is especially helpful with some vintage lenses that have unusual focus characteristics, such as the Bausch & Lomb Super Baltar lenses, Anamorphic lenses or vintage Soviet lens designs such as LOMO.

Calibrating FFD on Digital Cinema Cameras

The ability to see a highly magnified collimator image on an HD screen also makes very accurate adjustment of the Flange Focal Distance (FFD, sometimes incorrectly called “back focus”) of Digital Cinema cameras possible.

You can view the image on the monitor while turning the FFD adjustment screw (on RED cameras, for example) or moving the focus scale on your test lens (for cameras that use shims under the lens mount, such as ARRI cameras). You can easily see where the best focus setting is.

Adjustment of the camera’s FFD with a well calibrated high resoultion test lens is the most accurate method of setting FFD. Accurate setting of FFD on your cameras eliminates complaints from customers using their own improperly calibrated lenses.


The upgrade is available as an “eyepiece only” version, or complete with the HD video relay. The initial upgrade must be installed at CinemaTechnic as the R-2 block must be modified. The eyepiece only version can be upgraded to the HD video relay version and this can be installed by the user.

We strongly recommend having us service and calibrate your R-2 collimator block while doing the upgrade.

Current production of these units is back-ordered. We will be doing a short production run in the near future, but availability will be limited to units pre-ordered. If you would like to have your Richter Collimator upgraded, please get in touch via email.

To Clients and Friends of CinemaTechnic:

CinemaTechnic, LLC no longer conducts business in the State of California as of June 30, 2019.

We have reached this difficult decision after coming to the conclusion that a radical change in direction is necessary in order to ensure our future success.

This does not mean the end – it is a transition and a new beginning. The process of re-booting has already begun.

The cinematechnic.com website will continue to operate as usual as an information resource to the professional cinematography community. However, many of the products and services offered on these pages have been discontinued.

We want to take this opportunity to thank all of our clients and partners that have supported us during these three and a half years as an independent business in the Los Angeles area.

Richter Collimators Systems and Upgrades for Cine Lens Testing

Super-Precision Collimator Systems for Cine Lens Testing

Updated 4 January 2019

UPDATE: New CinemaTechnic lens testing mounts “Standards”  for Richter Cine Collimators and Lens Projectors are now available. We can supply most SLR and rangefinder lens mounts such as Canon FD, Canon EF, Nikon F, Leica M and Leica R. A Sony E / NEX mount is in development.

The CinemaTechnic IMS (Interchangeable Mount System) upgrade for Richter Cine Collimators and Test Projectors is also now available.

CinemaTechnic is developing focus testing collimator systems and upgrades for existing  collimator systems (Möeller-Wedel and Richter Cine).

Drawing on our two decades of experience with cine lens testing equipment, including state-of-the-art MTF testing systems by Carl Zeiss, we are bringing dependable precision lens testing and calibration within the reach of even small rental houses. Our new upgrades bring the venerable and affordable Richter Cine system into the 21st Century.

Richter Cine Collimator Systems – Reconditioned and Calibrated

We have used collimator systems available, although supply is very limited. The latest reconditioned and upgraded system is pictured above. It features the Digital Micrometer Upgrade and the LED Fiber Optic Illuminator with a proprietary Fiber Optic Adapter

The new Fiber Optic Adapter incorporates high quality diffusion, a spectral filter and condenser optics to assure even illumination of the collimator reticle. Along with the 5500ºK light from the LED Illuminator this combination greatly increases the ease of focus adjustment with the Richter Collimator, especially for vintage lenses that do not “snap” into focus as clearly as modern lenses do.

What is IMS Interchangeable Mount System?

The IMS system was introduced by P+S Technik in the 2000’s as an open standard positive locking intermediate lens mount. It is similar dimensionally to ARRI PL mount but has a smaller pilot diameter and a much shorter flange focal distance.

The IMS system has been adopted by manufacturers of high quality cine lens test equipment, such as Gecko-Cam (collimator and test projector) and P+S Technik (Lens Checker test projector).

IMS mounts are available for a wide variety of lens mounts. CinemaTechnic can manufacture IMS compatible mounts for many cine and still camera lens mounts.

NOTE: The relatively rare Richter Cine Lens Test Projector uses the same threaded mount, but requires special clearancing (larger I.D. and shorter thread length). Lens Test Projector compatible versions of our products are available on special order and require shipping of the lens projector to us for fit testing.

We also have Sony E (NEX) mount  and C/CS mounts for Richter Cine under development.

Please contact:

NOTE: Products pictured above are prototypes. The production versions will differ slightly due to ongoing incremental updates to the design.

Zeiss Oktoberfest Event and Lens Talk

Spherical Aberration f1.5
Example of spherical aberration at f1.5

Ever wonder what spherical aberration is or what it -really- looks like? I’m not using any kind of diffusion filter, this the image produced by a vintage lens at f1.5. To me, it looks like a toy Ad from the ’80’s.

The image above is one of the examples I created for my lens talk, “What Do Cinematographers Really Want in a Lens?” which I’ll be giving today, October 11, as part of Zeiss Cinema Lens Oktoberfest in conjunction with Hot Rod Cameras at our Burbank location 722 N. Mariposa Street, Burbank, CA 91506. The event runs from 3:00 to 6:30 pm.

I’ll be discussing desirable technical an aesthetic qualities in a lens, what all those aberrations really mean, and the challenges that lens designers have to work with. You’ll also get hand-on time with all the latest Carl Zeiss still and cine lenses such as the CP.3, Otus, Milvus, Batis, Loxia and Touit. I hope you’ll join us.

Seating is limited. There will be refreshements AND BBQ! So RSVP now before your spot is gone:
