Windows are applied to isolate different
physical environments while allowing light to pass. When
selecting windows you should consider materials, transmission,
scattering, wavefront distortion, parallelism and resistance
to certain environment. Tempotec offers a wide range of
different materials and different degree of precision windows. |
