-
- For splitting or combining light beams
- No angular or lateral deflection of transmitted beams
- Reflected and transmitted beams transit identical optical paths
- Compact, rugged units
- Designed for use with low-power lasers (0.1 J / cm2 for 10 ns pulses at 1064 nm)
- Optionally available with other beamsplitting ratios
- N-BK7 glass
- Reflectance ≈ transmittance ± 5 % for unpolarized light
- Absorption < 5 %
- Broadband AR-coated (ARB2-NIR)
- 8 arcmin angular beam deflection tolerance
-
- For higher quantities, customized versions (other sizes, materials, coatings)available on request.
- Recommended holder for beamsplitters with 10 mm edge length: Clamp Holder for Prism (G061641000).
