The Cooke Lens Test Projector is the first product in the new "Cooke Metrology" product line. It was developed for one of the most critical and demanding aspects of cinematography: to ensure that cinema lenses are adjusted and maintained to the highest standards possible. The Cooke Lens Test Projector functions like a slide projector, shining an even and bright light onto a reticle. The image is projected through the back of the lens onto a flat white wall. This allows testers to see how the lens handles geometric distortion of straight lines, whether there is chromatic aberration, internal barrel flare, sharpness, where the edges fall off (shading), if the lens breathes, etc.

Due to its innovative design and open aperture, the Cooke Lens Test Projector’s light output is the highest of any lens projector available today, allowing the user to judge and adjust even the fastest high speed lenses. Cooke Metrology’s projector is so bright it can be demonstrated in daylight.

Too bright? No problem. Simply turn the dimmer knob to adjust light output on the electronic ballast without changing color temperature. Color stability and uniform illumination across the entire field is an essential part of Cooke's projector design, assuring easier judgment, focus and test repeatability on any lens.

In addition to PL-mount lenses, the projector’s interchangeable lens mount system accommodates a variety of other mount types like, Panavision, Canon, Nikon, BNC-R and more.

The weighted lens projector base means you can test heavy zoom lenses without having to mount the projector onto a base or stand, making it transportable and convenient. Safely and easily work on telephoto lenses by using the available lens support mount with 19mm support rods.
