OPTICAL COMPONENTS Metallized Cube Beamsplitters Spherical Lenses Cylindrical Lenses Lens Kits Achromatic Doublets Multi-Element Micro Optics Mirrors Prisms Substrates & Windows Beamsplitters Polarizers All four faces AR coated and flat to λ/4 Inexpensive, yet effective for many beamsplitting requirements Both transmission/reflection typically 25% - with 50% absorption Standard cubes from 10 to 30mm For white light applications where even intensity splitting is required over a broad wavelength region these simple cubes, with metallic coatings, make an ideal beamsplitter. Filter & Apertures Specifications & Tolerances Surface flatness: λ/4 Dimensions: ±0.2mm Surface quality: 40-20 Beam deviation: ≤10arcmin Transmission: Tav = 30%, 400-700nm Material: BK7, grade A Tav= 30%, 780-850nm Metallic coatings absorb about 40-50% of the incident energy transmitting typically 25% to one beam energy is limited (or often even worse, in high power applications) this energy loss may be unacceptable. In those situations METALLIC BEAMSPLITTER P-POL TRANSMITTANCE AVG-POL 400-700 nm METALLIC BEAMSPLITTER P-POL TRANSMITTANCE AVG-POL 780-850 nm all-dielectric coatings will be preferred. Metallized Cube Beamsplitters Wavelength Range (nm) ORDERING & TECHNICAL SUPPORT Cube Side, a (inches) (mm) PART NUMBER Larger cube beamsplitters are available on request. 188
