Quality Control Laboratory

All components are subject to high quality testing and certifications in Quality Control laboratory. Through stringent inspection procedures, quality control assessments and commitment to new advanced technologies, we are continuously improving and delivering exceptional quality.
The QC laboratory has vibration-isolated optical benches, laminar flow hoods and ultrasonic cleaners. It is equipped with high-precision measurement equipment to perform a wide variety of tests including:

- determination of optical and geometrical parameters, e.g. focal length, radius of curvature, crystals cut angles, optical axis or orientation determination, etc.;

- determination of polished surface quality according to MIL, ISO or DIN standards;

- flatness and wavefront distortion measurements (reflected or/and transmitted beams);

- prisms and wedges angles measurements and parallelism measurement of flat components;

- materials and thin-film coating spectral or/and angular reflectance and transmission.
