Features

• Beamsplitter cube
• Cube beamsplitters are constructed by cementing two precision right angle prism together with appropriate interference coating on the hypotenuse surface. The absorption loss to the coating is minimal transmission and reflection approach 50%(average) though output is partially polarized. If polarization sensitivity is critical to your application, we recommend that Polarization Cube Beamsplitter or Non-Polarization Cube Beamsplitter
• Broadband Neutral Plate Beamsplitte
• For low power applications these plate beamsplitters provide a spectrally neutral reflectivity over a broad spectrum. The transmission and reflection values are equal within 3% over the entire visible spectrum. They utilize a thin film of Inconel alloy, which is both durable and of neutral density over a wide wavelength range. This film is deposited on BK7 optical glass or UV fused silica. The resulting beamsplitters are useful for applications spanning the visible to the near infra-red (350 - 2500 nm) when using BK7. If required for use in the UV, the range can be extended down to 200 nm by using UV fused silica substrate material.
• Polarization beamsplitter cube
• Thin film stacks, deposited on the internal surface of a cube beamsplitter can produce effective polarizers. The coatings are designed to provide almost total reflection of the s-component and a very high transmission of the p-component. They operate over a broad spectral bandwidth. A useful extinction ratio 500:1 can be obtained using high index SF2 glass. This extinction ratio covers a bandwidth of either 440-680 nm, 650-1000 nm, 900-1400 nm or 1200-1600 nm, centred on 550, 800, 1000 and 1400 nm respectively. A lower cost form of polarizing beamsplitter can be supplied for the visible bandwidth using BK7 glass a substrate.
• Laser-line Beamsplitters
• We can produce all kinds of Laser-line Beamsplitters,such as
• (i)Near IR Laser Line Partial Reflectance Plate Beamsplitters
• (ii)Laser Line Non-Polarizing Plate Beamsplitters
• (iii)Laser Line Partial Reflectance Cube Beamsplitters
• (iv)Laser Line Non-Polarizing Cube Beamsplitters
• Beam Samplers
• These beam-samplers are useful for beam diagnostics and monitoring. They are manufactured to work at 45 degrees incidence. When they transmit the main beam, they sample 4% of the input or so. The sample beam is provided by the natural reflectivity of the surface. The back surface with broadband antireflection coating can eliminate errors from back surface reflections with a high efficiency
