Products: VUV/UV Laser Beamsplitters

VUV/UV Laser Beamsplitters image

These multilayer, dielectric, low-absorption coatings are ideal for laser output couplers and beam-splitting applications. Beamsplitters of all wavelength ranges from 126 nm to 353 nm are calibrated for reflectance and transmittance at the laser wavelength and angle of incidence specified to ensure excellent performance in high-power laser applications. Standard beamsplitters are designed for random polarization.

Acton Optics & Coatings can custom-design beamsplitters for your application by optimizing for horizontal “P” polarization or vertical “S” polarization and other requirements. If required, anti-reflection coatings are available for the rear surface of beamsplitters. Coatings are available on Acton’s standard substrates. 

Note: Coatings can be applied to Acton standard mirror blanks, custom substrates, and customer-supplied material (CSM). Contact us at info@actonoptics.com for more details.

NOTE:  Beamsplitter Coating Part Numbers (Based on % Transmission)

For Complete Beamsplitter:
Coating Part # + Substrate Part # =
Complete Beamsplitter

For example:
To order a 308nm, 45° beamsplitter with 30% transmittance on a 1.0” flat UV grade fused silica substrate:
Part # M308-P3045-1D-MB

Coatings for rear surface use must be specified by adding ‘-S2’ to coating part numbers.

Part numbers listed above are for 45° angle of incidence coating only. If normal incidence coatings are required, delete the ‘45’ from the coating part number.

Ex: Part # M193-P1045 would be Part # M193-P10.

Generally, laser grade UV fused silica substrates are recommended for beamsplitters above 170nm.

Beamsplitter coatings can be applied to customer supplied material.
