Non-Polarizing Plate Beamsplitters, UV Fused Silica, Circular — Model BS2055-B
Operating wavelength 700 nm-1100 nm, Ø12.7 mm, substrate UV Fused Silica.
Product Description
- Optical material: UV Fused Silica
- Operating wavelength: 400 nm-700 nm, 700 nm-1100 nm, 1100 nm-1650 nm
- Applications: beam splitting, beam combining
LBTEK's Non-Polarizing Plate Beamplitters are coated with a dielectric beamsplittier coating on one side and an anti-reflection coating on the other. When a light beam is incident on the beamsplitter coating surface at an angle of 45°, different splitting ratios can be achieved. Currently, five splitting ratios are available: 10:90, 30:70, 50:50, 70:30, and 90:10. The anti-reflection coating options include 400 nm-700 nm, 700 nm-1100 nm, and 1100 nm-1650 nm. The backside is coated with an anti-reflection coating to reduce reflections (ghost images). For applications sensitive to such phenomena, please consider using non-polarizing beamsplitter cubes. LBTEK also offers customization services for plate beamsplitters with other materials, sizes, and coating systems. If needed, please contact the technical support.

- Optical material: UV fused silica
- Applications: Beam splitting, Beam combining
- Diameter: 25.4 mm; Thickness: 5.0 mm
The LBTEK Circular Non-Polarizing Plate Beamsplitter has a diameter of 25.4 mm and a thickness of 5 mm, with one side coated with a dielectric beamsplitter coating and the other side coated with an anti-reflection coating. When the light beam is incident on the beamsplitting surface at an agle of 45°, different splitting ratios can be obtained. The arrow on the side of the product points to the surface coated with the beamsplitter coating, while the back side is coated with an anti-reflection coating to reduce back reflection (ghost images). For applications sensitive to ghosting, please consider using a non-polarizing beamsplitter cube. The splitting ratio accuracy is sensitive to the polarization state of the incident light. Please refer to the pages of performance curves for details.
