Digital Micro Alignment Telescope-Autocollimator OPTRO-PPS-031

Digital Micro Alignment Telescope-Autocollimator OPTRO-PPS-031 measures the non-straightlinearity, misalignment, non-perpendicularity, out-of-levelness of plane surfaces and aperture misalignment by sight tracking. This device was designed based on the operating experience of Alignment Telescope PPS-11 (LOMO).

OPTRO-PPS-031 provides automatic linear measurements of surface straightness, alignment and perpendicularity and aperture alignment errors on objects of up to 30 m in length without human intervention. CMOP camera is used as a measuring cell. Video data processing and computation of measurement results are enabled by special-purpose software.

Values of physical surface deviation from the line of sight are determined by a special sensor in two orthogonal planes.

During measurements a straight line passing across two points on the controlled surface is accepted as the basis.

If used with an autocollimating module (per Customer specification) the device can perform alignment by enabling visualization of the center of curvature of the mirror optical elements in the line of sight.

Conclusions:

1. The basic error of OPTRO-PPS-031 is 10 to 2 times as small compared to PPS-11.
2. OPTRO-PPS-031 provides automated measurements, direct measurement of deviations, as well as remote measurements, when the operator is away from the device.
