2. General Description
The Polarizing Beamsplitter Plate is a highly efficient optical component designed to split randomly polarized light into two linearly polarized beams. It reflects S-polarized light while allowing P-polarized light to pass through. This property is crucial for applications requiring distinct polarization control. These beamsplitters are widely used in laser systems and 3D projection displays, providing superior performance in managing polarized light. SOT’s Polarizing Beamsplitter Plates are fabricated with high precision and made from BK7 and fused silica, ensuring excellent durability and transmission. These plates exhibit minimal distortion, with a high extinction ratio of over 500:1, making them suitable for sensitive applications requiring high-contrast optical systems.
3. Spectrum Transmission Curves
SOT offers customized services for Polarizing Beamsplitter Plates to meet specific wavelength requirements. Customization options are available based on application-specific needs.
4. Coating Quality
- Adhesion Test: Compliant with MIL-C-675C military standards, the adhesion test involves applying a tape that meets LT-90 specifications onto the lens film layer, followed by vertical removal, performed three times without blistering or peeling.
- Temperature Test: Test pieces are subjected to -62±1℃ and 71±1℃. After being held at room temperature (16-32℃) for two hours, the adhesion test is repeated, with no film detachment.
- Abrasion Resistance Test: Complies with MIL-C-675C and CCC-C-440 standards. A gauze tester applies a minimum force of 1.0 lbs (0.45 kg) to the film 25 times, ensuring no surface damage.
- Humidity Test: The film remains intact when exposed to 49±2℃ and 95%-100% humidity for 24 hours, with no peeling or scratches.
- Solvent and Cleaning Test: Exposed to acetone and alcohol for at least 10 minutes each, followed by cleaning with alcohol-soaked cotton cloth. No peeling or scratches are observed.
- Salt Spray Test: After 100 hours in a 35°C environment with 5% saltwater, no signs of damage are observed.
