Metallized Plate Beamsplitters

Sizes and coatings are available upon your request. You could send us your specifications or drawings. We will be happy to return a quotation ASAP as the average response time is within 24 hours. Meanwhile our optical designers are always available to assist with your special needs, and our factories in China are ready to meet your quantity requirements. These beamsplitters provide a highly neutral reflectivity over the visible spectrum and are most useful for broadband or tunable wavelength applications. A separate coating, optimized for use at the near-IR diode wavelengths, is available. Features: 1) The thin metallic film acts as broadband partially transmitting mirror 2) Substrates polished both sides to /10 3) Wedged substrates (for ghost suppression) are also available as standard 4) Standard diameters from 25.4 to 100mm Specifications: 1) Material: BK7, grade A 2) Surface flatness: /10 3) Surface quality: 40 - 20 4) Thickness: +0.2mm 5) Bevel: 0.2mm x 45º typical 6) Reflectance: 7) Rav = 25%, 400 - 700nm 8) Rav = 30%, 700 - 900nm 9) Diameter: +0, -0.2mm 10) Parallelism: 90% diameter
