Beamsplitter

Beamsplitter plates / beamsplitter cubes

Beamsplitter plates with dielectric layers for separating or overlaying optical pathways. We manufacture standard plates with reflection to transmission ratios:

R : T = 30 : 70; R : T = 50 : 50; R : T = 70 : 30

Optional: rear antireflection coating

Beamsplitter cubes with metallic or dielectric layers for separating or combining optical pathways. Polarizing or non-polarizing for ranges UV – VIS – NIR.
