Optical Calibration Equipment
The specialized tools required to analyze and calibrate high-quality professional lenses are a combination of precision optics and mechanics, as well as computer hardware and software. Owning these tools, as well as our skill and experience with using them, makes for a dedicated world-class optics service department.
A measurement of contrast, MTF (Modulation Transfer Function) is the most widely used scientific method of describing lens performance – it's also the criteria by which we measure the image quality of lenses. MTF measures how faithfully the lens reproduces (or transfers) detail from the object to the image produced by the lens. Both our New York and Burbank offices are equipped with a ZEISS K9 MTF System, which allows for a quick check of back focus and focus scale accuracy in one setup, with one micron (1/1000th millimeter) precision. Both coasts also use autocollimators for backfocus checks, as well as projectors, and ZEISS Torque Testers for further adjustments.
Our Burbank location is also home to our ZEISS K8 Vertical MTF System. The K8 not only measures MTF, but also easily detects field curvature, chromatic aberration, and whether the optics are properly aligned. The ZEISS T-Stop Tester, which is used to measure the effective transmission aperture of photographic and cinematographic lenses, is also exclusive to our Burbank repair center.
