Description
- Features
- High Reflection: Offers excellent reflection for S-polarized light while efficiently transmitting P-polarized light.
- High Transmission: Ensures minimal loss of intensity in the transmitted P-polarized light.
- High Extinction Ratio: Excellent ratio between the transmitted and reflected beams for high-precision applications.
- Wide Wavelength Range: Suitable for a broad range of wavelengths, from visible to infrared.
- Precise Beam Splitting: Splits randomly polarized light into two linearly polarized components for improved optical performance in complex systems.
- General Description
Polarizing Beam Splitter Cubes are optical components designed to split randomly polarized beams into two linearly polarized components, providing a highly efficient and accurate method for managing polarization in optical systems. Typically, S-polarized light is reflected by the beam splitter while P-polarized light passes through. This property makes them an essential part of many optical instruments, including AR glasses, 3D projection displays, and various imaging systems. Shape Optics Technologies Pte Ltd (SOT) offers these beam splitters in a variety of wavelengths ranging from 488nm to 1200nm. The excellent extinction ratio ensures high contrast between transmitted and reflected beams, making them ideal for use in sensitive applications such as military, aerospace, and biomedical fields.
- Spectrum Transmission Curves
If standard components are not available, SOT offers customized services for Polarizing Beam Splitter Cubes, which can be tailored to your specific wavelength needs. We can customize according to your actual application requirements.
- Coating Quality
- Adhesion Test: SOT’s coatings comply with MIL-C-675C military standards. The adhesion test involves applying a tape that meets LT-90 specifications to the lens film layer and removing it vertically three times, with no blistering or peeling.
- Temperature Test: Test pieces are subjected to temperatures of -62±1°C and 71±1°C as per MIL-C-675C standards. After two hours at room temperature (16-32°C), no film detachment occurs.
- Abrasion Resistance Test: SOT’s films conform to MIL-C-675C and CCC-C-440 standards. The abrasion resistance test involves applying a minimum force of 1.0 lbs (0.45 kg) with a gauze tester, repeated 25 times without damaging the film surface.
- Humidity Test: The test piece remains intact in controlled temperature and humidity (49±2°C, 95%-100% humidity) for 24 hours, with no peeling, scratches, or defects.
- Solvent and Cleaning Test: After exposure to acetone and alcohol for 10 minutes, followed by cleaning with a cotton cloth soaked in alcohol, the film shows no signs of peeling or scratches.
- Salt Spray Test: After 100 hours in a 35°C environment with a 5% saltwater concentration, the film shows no signs of damage.
