Interferometer OptoTL-250

The OptoTL-250 interferometer is designed for non-contact technological testing of the shape accuracy (N / ΔN) of optical polished flat surfaces up to 250 mm in diameter, distortion of the passing wavefront of plane-parallel and wedged windows.

Typical features of the OptoTL– 250 interferometer:

• small dimensions;
• specially developed original FastInterf software for real-time measurements in production conditions;
• availability of two monitors for fast alignment and visualization of the interference pattern;
• New! the presence of two light sources (coherent and incoherent) to reduce the influence of the reflection of the second surface when testing plane-parallel plates (optional);
• motorized vertical movement by servomotor;
• emergency movement stop block when approaching too close to the tested component to prevent contact of the test plane with the controlled surface (optional)
• translation stage for tilting the controlled parts;
• base made of natural stone, vertical stand made of sintegran for better vibration damping;
• passive vibration isolation system sufficient for work in industrial conditions;
• measurement of the wedge shape of transparent windows (with an additional reference plane) (optional)
• interferometer is supplied on a turnkey basis complete with everything you need to set up and get started.
