Cut off red optical glass HB630

Cut off red optical glass HB630 is a high-performance optical filter material, with the following core characteristics: (Cut off orange glass,Cut off red glass,Cut off golden glass,Cut off infrared transmission visible absorption glass) 1. Spectral characteristics Long wave pass filter, accurately cutting off ultraviolet and visible light with wavelengths below 630nm; Allow red and near-infrared light above 630nm (up to 2500nm) to pass through; Has angle insensitivity and maintains stable center wavelength at different incident angles; The peak transmittance can reach 85% -90% (in the red light region); 2. Optical performance Adopting RG630 optical glass material, with stable infrared transmission performance; Maintain light consistency under long-term exposure, with minimal impact of temperature changes; Surface smoothness of 60/40 or higher standard; Excellent chemical stability, suitable for complex environments; 3. Physical characteristics The standard thickness is 2mm (custom…
