K9 glass wedge window plates are high-quality optical components made from K9 borosilicate glass, recognized for their exceptional transparency, durability, and resistance to thermal expansion. These wedge-shaped windows are designed to minimize reflections and optical distortions, making them ideal for laser systems, optical instruments, precision imaging technologies, and scientific applications. Their stable mechanical properties ensure consistent performance in various environmental conditions.
Product Overview
K9 glass wedge window plates are specialized optical components made from high-quality K9 optical glass. With their unique wedge shape, they are commonly used in optical systems as beam control devices. The wedge design effectively eliminates interference patterns, prevents external cavity feedback, and protects laser output from external environmental disturbances, thereby improving the stability of laser systems. K9 glass offers high transparency and a low refractive index, making these window plates highly effective in a wide range of optical applications.
Key Features
- High Transparency: K9 glass has excellent transparency, efficiently transmitting visible light, near-infrared, and part of the ultraviolet spectrum, thus enhancing the optical system's transmission efficiency.
- Elimination of Interference Effects: The wedge design, with two non-parallel planes, effectively prevents interference effects (Etalon effect) caused by reflected light from the front and rear surfaces, improving system stability and accuracy.
- High Laser Damage Threshold: K9 glass has a high laser damage threshold, making it suitable for high-power optical systems such as laser processing and LiDAR, as it can withstand laser exposure without damage.
- High Mechanical Strength: K9 glass is hard and wear-resistant, capable of withstanding mechanical wear and chemical corrosion in harsh environments, ensuring the long-term stability of optical components.
- Easy to Process: K9 glass can be precisely processed through cutting, grinding, and polishing techniques to meet the needs of various optical systems. Custom wedge window plate sizes and specifications can also be tailored according to specific requirements.
Applications
- Laser Systems: K9 glass wedge window plates are widely used in laser systems to improve output stability, prevent cavity feedback, and enhance laser quality.
