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. ​
