Polarized UV exposure system uses Mercury Xenon lamp and a combination of UV dichroic mirror(cold mirror)
and an optical integrator realizes a UV exposure with a polarized beam.
Extinction ratio of 50 to 1 or better can be achieved.
Also with a combination of high transmission interference filter, system can expose a selected UV wavelength.
Custom design is available for different exposure area or radiation intensity, please contact our sales department.
