OPTICAL COMPONENTS Spherical Lenses Cylindrical Lenses Lens Kits Achromatic Doublets Multi-Element Micro Optics Mirrors Prisms Substrates & Windows Broadband Cube Beamsplitters Four wide wavelength regions for complete coverage of visible and near-IR Օ Cube faces AR coated to prevent ghosts Standard cubes from 5 to 30mm Օ All coatings are multilayer dielectric 5mm beamsplitter cubes available for fiber optic applications Beamsplitters Polarizers Filter & Apertures These beamsplitters are suited to a wide variety of general, high performance beamsplitting applications. The sizes listed are standard and we keep most configurations and wavelength regions in stock at all times for immediate delivery. If you need even faster service, ask about our next-day delivery option. These superior broadband beamsplitters use multilayer dielectric films to produce approximately equal reflectance and transmittance over a broad range of wavelengths. Three different wavelength ranges are offered covering the visible and near infra-red spectrum, as shown on the opposite page. The beamsplitting film is deposited on the hypotenuse face of a precision BK7 prism whose faces are Հ/4 and the prism is cemented to an identical prism to form a cube which is parallel sided within 5arcmin. The four outer faces are all Anti-Reflection (AR) coated. Four sizes are offered including a very small 5mm cube which is ideal for fiber optic applications and other uses in which small configurations are required. Standard sizes are 5,10,15 and 20mm. Larger sizes are available on request.
