collimator with double micrometer
TYPE K MD
A collimator with double micrometer allows the setting of defined image angles in two directions. The movement of the reticle in x- and y-direction in the focal plane is measured with measuring drums. The scale division (SD) is 5 µm.
Application areas:
■ Measurement of angular tilt (in conjunction with a telescope)
■ Qualitative testing of the imaging properties of optical elements and systems
Notes on ordering:
■ One reticle and 6V/5W illumination w/cord are included.
■ If not specified otherwise, the collimator is adjusted to infinity at 546 nm wavelength. Adjustment to other distances or other wavelengths is also possible on demand.
■ The nomenclature of the collimators with double micrometer is as follows:
Important:
Please specify the reticle and illumination when ordering.
