FIVE REASONS WHY ZEISS SHARP MAX™ UNIVERSAL IS THE SUPERIOR PORTABLE COLLIMATOR

1. Absolute Accuracy
The Carl Zeiss Sharp Max™ Universal uses a 72-sectored Siemens star as an internal test target. This multi-sectored version provides a quick and accurate visual detection of the maximum sharpness. Other collimators use an inexpensive 18-sectored Siemns star, severly compromising accurate sharpness detection.

2. Athermal Design
The Carl Zeiss Sharp Max Universal's athermal design and build, utilizes expensive exotic materials like INVARSTAHL®. The internal optics and mechanics do not change accuracy due to large temperature variations found on many sets. This means that the sharpness readout is reliable and independent of ambient temperatures. Other collimators completely ignore the problems associated with changing temperatures, compromising repeatability and accuracy.

3. Carl Zeiss Optics
The Zeiss Sharp Max Universal optics are of the highest optical quality and are corrected for spherical aberration, meaning that the sharpness readout reliably stays the same regardless of the aperture setting on the camera lens. Other collimators use under-corrected optics, we believe to be of insufficient quality, which produce different back focus readouts at different aperture settings on the same camera lens, making the back focus calibration unreliable and thus worthless.

4. Accuracy throughout the Range
The optical system of the Carl Zeiss Sharp Max Universal provides sufficent accuracy of the collimation process for all focal lengths in the DigiPrime lens range. Other collimators incorporate inadequate optics which cannot provide sufficiently accurate results with lenses with focal lengths of 40mm and longer.

5. Well-Designed with Thoughtful Features
The brightness of the Zeiss Sharp Max Universal test target can be user-adjusted. Other collimators use a simple consumer grade flashlight for illumination with no means of brightness adjustment. Rechargeable batteries can be used and can be recharged by the Zeiss Sharp Max Universal's internal circuitry, once external power is connected. Other collimators are unable to re-charge their batteries. The Zeiss Sharp Max Universal can be powered externally by the camera and by other power 12V power sources. Other collimators fail to provide multiple power options.

Conclusion
In an industry in which the consistency of the final result is so critically important to the overall success of the enterprise, and where the cost of re-shooting or other post-production manipulation can be extremely high, the value of the Zeiss Sharp Max Universal becomes immediately apparent. Anything less would be false economy. We invite you to investigate this for yourselves.
