UV Partial Reflectance Plate Beamsplitters

These beamsplitters provide definite split ratios at a particular  UV wavelength.  They are designed for use either at 0° or 45°and are not intended for use at other wavelengths.  Substrate material is UV fused silica and the substrates are polished to laser quality standards.

They may be used to split  light into separate components or to re-combine branches of an optical system. 

These beamsplitters may be used with high power lasers.  They have a high laser damage threshold.

 Common wavelengths offered are: 193, 213, 248, 257, 266, 308, 325, 352, 355 nm.

Reflectance can be: 5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 65, 70, 75, 80, 85, 90, 95, 98 or 99 %

Usual diameters are 10, 12.7, 19.1, 20, 25.4, 30, 38.1 and 50.8 mm but other sizes can be supplied on request.
