Mirrors
Optical mirrors are used in optical – electronic devices, laser technology, spectrographs, telescopes and other devices.
Certificated
The performance of the mirror boil down to the beam deviation, their translational displacement and to the image reversal.
Mirrors are made of individual sizes and configurations, flat, spherical, with holes, having a highly reflective mirror surface from optical and sheet glass.
