Since its foundation in 1913, Schneider-Kreuznach has acquired many German and international patents in the field of precision mechanics/optics based on its core competencies. This has resulted in many brands such as Xenon, Symmar, Xenoplan, Variogon, Cinelux, etc.
Learn moreThe human eye perceives wavelengths between 0.400 μm (blue) and 0.700 μm (red) as white light. Standard lenses are optimized for white light, but issues can arise with non-white light sources in digital camera-based vision systems. Defining lighting requirements early is crucial. A case example using a 75 mm f/3.0 lens is discussed, focusing on selecting wavelengths and achieving desired modulation transfer function (MTF) values.
