Optical lens insulating glass is a special glass material that combines optical performance with thermal insulation function. It primarily reduces heat transfer by selectively absorbing or reflecting specific wavelengths of light (especially infrared rays) while ensuring high transmittance of visible light. Its core characteristics include a balance between high visible light transmittance and infrared blocking capability, making it widely applicable in scenarios requiring both optical clarity and temperature control, such as optical instruments, building energy efficiency, imaging equipment, and other fields.

Main Types and Technical Parameters of Optical Lens Insulating Glass

Classification by Material and Function

• Selective Absorption Insulating Glass
  • GRB Series (e.g., GRB1, GRB2, GRB3): Achieves selective absorption of infrared rays by adding metal ions, with high visible light transmittance, suitable for precision equipment such as optical measuring instruments and digital cameras.
  • KG Series (e.g., KG5): Bluish-tempered insulating glass, belonging to the selective absorption type, with significant absorption of the 1000 nm infrared band, commonly used in high-definition projectors and stage lighting systems.
  • XRB1/XRB3: XRB1 is phosphate absorption glass, and XRB3 is silicate absorption glass, both nearly colorless, suitable for scenarios with high requirements for light intensity (such as financial machinery and currency verification equipment).
• Coated Insulating Glass
  Reflects infrared rays through surface coatings (e.g., nano-powder layers), directly reducing heat transfer, often used in building curtain walls and automotive window films, achieving an indoor-outdoor temperature difference of 3-6°C;
