Economical Plate Beamsplitters, Circular — Model BS6737
Operating wavelength 450 nm-650 nm, Ø25.4 mm, substrate Soda Lime.
Product Description
- Optical material: soda-lime glass
- Operating wavelength: 450 nm-650 nm
- Applications: beam splitting
The LBTEK Economical Plate Beamsplitters are coated with a dielectric beamsplitter coating on one side. When the non-polarized light is incident on the coated surface at an angle of 45°, a splitting ratio of 30:70 can be achieved in the visible spectrum (450 nm-650 nm). Backside reflections may cause interference in the reflected light. For applications sensitive to such phenomena, please consider using non-polarizing beamsplitter cubes. LBTEK selects soda-lime glass to manufacture plate beamsplitters in various sizes.
