Sale of beam splitters

Beam splitters are available from multiple suppliers with prices ranging from tens to hundreds of dollars depending on type, coating, and precision requirements.Types and PricingBeam splitters are optical devices that divide an incident light beam into two or more beams, with variations in geometry, polarization, and coating affecting performance and cost . Common types include:Cube Beam Splitters: Cemented or optically contacted prisms; minimal beam displacement; suitable for imaging and interferometry. Prices typically range from $50 to $500 for standard visible-range units, with higher-end fused silica or precision-coated cubes costing more .Plate Beam Splitters: Thin glass plates at an angle; higher damage thresholds (up to 5 J/cm² @ 1064 nm); may introduce beam displacement. Prices are similar to cubes but can increase for high-power or UV/NIR applications .Polarizing vs. Non-Polarizing: Polarizing splitters separate light by polarization, while non-polarizing maintain intensity ratios regardless of polarization. Polarizing types generally cost more due to specialized coatings .Supplier OptionsDigiKey: Offers a large in-stock selection with same-day shipping; pricing is available online and can be filtered by type and wavelength .Photonics Marketplace: Lists over 150 manufacturers, including FOCtek Photonics, Advanced Optics, and Nanyang Jingliang, offering both standard and custom beam splitters with detailed specifications .Made-in-China: Provides wholesale options for bulk purchases, often at lower unit prices for industrial applications .Accio: Offers detailed product comparisons, including cube and plate splitters, with specifications for medical, industrial, and research applications. Minimum order quantities vary from 1 piece for prototyping to 100+ for industrial automation .Key Considerations for PricingWavelength Range: Standard visible (400–700 nm) vs. UV (190–400 nm) or NIR (700–2000 nm) affects cost .Splitting Ratio Tolerance: Industrial grade ±5%, research grade ±1%; tighter tolerances increase price .Surface Quality: Scratch-dig specifications (e.g., 60-40 for illumination, 10-5 for precision metrology) influence cost .Material and Coating: Fused silica, AR coatings, and dielectric coatings for high precision or high-power applications increase price .After-Sales Support: Calibration, coating refurbishment, and technical documentation may add value but also affect cost .SummaryFor a price quote, standard visible-range cube or plate beam splitters typically start around $50–$100 per unit, with high-precision, UV/NIR, or custom-coated units reaching $500 or more. Suppliers like DigiKey, Photonics Marketplace, and Accio provide both off-the-shelf and custom options, with minimum order quantities ranging from 1 piece for prototyping to 100+ for industrial applications. When requesting a quote, specify type, wavelength, splitting ratio, surface quality, and coating requirements to receive accurate pricing.
