Fused quartz wedge plates are high-performance optical components known for their exceptional purity, superior ultraviolet and infrared transmission, and precise beam deviation capabilities. Manufactured from high-purity fused quartz, these wedge-shaped plates provide outstanding optical clarity, minimal optical distortion, and excellent resistance to thermal fluctuations. They are widely used in laser systems, spectroscopy, aerospace applications, and precision scientific instrumentation due to their durability and optical stability.
Product Overview
Fused quartz wedge plates are optical components made from high-quality fused quartz material, featuring a unique wedge shape. These plates are primarily used for beam control, where the precise wedge design helps eliminate interference effects caused by reflected light from high-parallelism windows. This improves the stability and accuracy of optical systems. The wedge plate deflects the incident beam by a specific angle, making it suitable for precision optical systems such as lasers and spectrometers.
Key Features
- High Transparency: Fused quartz has excellent light transmission, especially in the UV to near-infrared wavelength range.
