Visual collimator Type KM

for camera lenses

The motorized collimators of the KM product line were developed for the „Active Alignment“ of cameras for the automotive industry. The high-precision linear motion guide, modular design and simple command structure allow customers to integrate these OEM collimators into their custom measurement setups easily. The motorized collimators are designed to fulfill the high demands in the automotive industry for flexible use, fast interchangeability, easy integration into own software applications. The collimators can also be adapted to different test specimen specifications or measurement tasks easliy. In addition to 6 different focal lengths, two filter variants (machine vision, human vision) are available. The high-precision motorized linear guide has a travel of ±9 mm. Additionally, the linear guide can be supplied with a length measuring system to increase position repeatability and reproducibility. Depending on the focal length of the collimator, the travel distance allows imaging distances from +0.1 m to ∞ and from -∞ to - 0.1 m. The machine vision filter (white light filter) has an almost constant intensity distribution over the entire visible spectrum and has a color temperature of approx. 5700K. The human vision filter reproduces the sensitivity curve of the human eye (photopic eye filter) and has its maximum sensitivity at approx. 520 nm. A special diffuser ensures high homogeneity (Lambert characteristic) over the whole reticle structure. The collimators can be supplied with different reticle patterns for MTF applications (e.g. 10 µm crossline, negative) or SFR (e.g. chessboard pattern).
