has a huge inventory of used, new, pre-owned, recycled and refurbished Autocollimators for sale. The capability of the developed autocollimator for the angular measurement of rough surfaces was demonstrated through experiments. Pictured set up to demonstrate working condition. extensive accessories (mounting plates, basis mirror, stands, laser. Furthermore, an autocollimation unit was designed and constructed for detecting the angular displacement of mid-infrared laser light reflected from a target surface. Visual autocollimator of Moeller-Wedel, equipped with megapixel camera and highly.

Therefore, a continuous-wave mode fluoride glass fiber based mid-infrared laser was developed for the autocollimator. Laser autocollimator Download PDF Info Publication number US3542478A.
The suitability of a mid-infrared laser in an autocollimator for the angular measurement of rough surfaces (sub-micrometer level) was verified through simulations using reflection models. This product is ideally suited for the measurement of small optical components, surfac. Although a conventional autocollimator using a visible laser has a high resolution of angular measurement, it can only be used to measure mirror surfaces because the intensity distribution of the reflected light from a rough surface changes significantly due to the influence of diffused reflection. Laser autocollimator uses the semiconductor laser as the light source. A mid-infrared laser having a wavelength of 2.8 μm was employed as the light source because it possesses high specular reflectivity on rough surfaces. In this study, we proposed an autocollimator for the angular measurement of rough surfaces.
