TeO2 crystals - the most effective material and components for laser beam control and characteristics changing

Devices on TeO2 blocks can be effectively and successfully used for signal modulation (AO Modulators), deflection (AO Deflectors) and selection (AOTF).


Polarizing optics based on birefringence crystal properties and standard materials are Calcite (VIS-NIR), Rutil (NIR) but we'd like to offer to use high stable quality TeO2 material.
This new for Polarizing optic material can substitute both standard materials and can be successfully used for VIS – MIR.
