Introduction:
Non-Polarizing Beamsplitters divide incident beam into a specific percentage without altering the S and P-polarization state. CASTECH offers a variety of Non-Polarizing Beamsplitters in configuration including UV Laser Line Non-Polarizing Beamsplitter Cubes, Laser Line Non-Polarizing Beamsplitter Cubes, Broadband Non-Polarizing Beamsplitter Cubes, Broadband Non-Polarizing Plate Beamsplitters, Laser Line Non-Polarizing Plate Beamsplitters. Equipped with state-of-art coaters, our Beamsplitters are coated with all-dielectric coatings or broadband metal-dielectric hybrid coatings to increase system performance while maintaining high laser damage thresholds.
Features:
- Material from DUV to IR
- Custom dimension and shapes
- Diameter from 1 to 100 mm
- Custom beamsplitting coatings
- High laser damage threshold
