Optical Grade Borosilicate Glass Discs with High Transparency
Material
The product consists of borosilicate glass, specifically engineered to meet stringent optical grade standards. This formulation ensures minimal inherent impurities and maximal material homogeneity, making it superior to standard glass or plastic sheets for critical applications.
Key Properties
Exceptional Light Transmission: The primary characteristic is its high transparency across a broad spectrum, often exceeding 92% visible light transmission with minimal wavefront distortion.
Superior Thermal & Chemical Stability: It exhibits outstanding resistance to thermal shock, capable of withstanding rapid temperature changes without cracking. The material is also highly inert, resisting water, acids, and solvents.
Excellent Optical Homogeneity: The glass is manufactured with a high Abbe number and low inclusion content, ensuring consistent refractive index throughout the disc and minimizing birefringence for precision applications.
Surface Quality & Hardness: The discs can be produced with fine surface finishes and are inherently scratch-resistant, maintaining clarity and integrity over long-term use.
Primary Function
These glass discs function as high-performance viewing windows, protective covers, and optical substrates. Their core role is to provide a durable, transparent barrier that protects sensitive internal components (like sensors, LEDs, or electronics) from dust, moisture, chemicals, and physical damage, while introducing minimal optical distortion.
Applications
These versatile discs are essential components in a wide range of high-tech and demanding environments, including:
Optical Systems: As windows, filters, and mirror substrates in spectrometers, projectors, and laser equipment.
Technical Lighting: Serving as protective covers for high-power LED arrays, UV lighting systems, and industrial process lamps.
Medical & Analytical Devices: Used in sight glasses for sensors, medical instrument windows, and laboratory equipment.
Industrial Machinery: Acting as durable viewing ports for furnaces, chemical process vessels, and automated inspection systems.
Consumer Electronics: For covers on high-end sensors and specialized displays.
In summary, optical grade borosilicate glass discs are a critical enabling material for engineers and designers building reliable systems where superior transparency, durability, and stability cannot be compromised.
