The OptoTL-60/125 interferometer by Opto-TL is designed for non-contact technological control of the shape accuracy (N/ΔN) of optical polished flat and spherical surfaces with a diameter of up to 125 mm, measuring their radii, and also for checking the distortion of lens wavefronts. Characteristic features of the interferometer OptoTL-60/125: • small dimensions for placement in production next to optical machines; • specially developed original FastInterf software for operational measurements in production conditions; • original ruler calibration program for measuring radii; • the presence of two monitors for quick adjustment and visualization of the interference pattern; • New! the presence of two light sources (coherent and non-coherent) to reduce the influence of reflection of the second side when testing plane-parallel plates (option); • motorized fast vertical movement by servomotor; • motorized precise vertical movement using a pulse generator with a sensitivity of 30 nm; • New!automatic vertical movement by a specified amount (from the «cat's eye» position to the confocal position and vice versa) (option); • two standard sizes of reference lenses 60 mm and 125 mm with adapter 60/125; • adjusting table for tilting and moving the controlled samples; • the presence of base surfaces for the table and controlled parts to simplify alignment when controlling a batch of identical parts; • device for tilting steep blocks (option); • base and vertical stand made of syntegran for better damping of vibrations; • passive system of vibration isolation sufficient for work in industrial conditions; • The interferometer is delivered on a turnkey basis, complete with everything you need to get it up and running.
