Cut off red optical glass HB600

Cut off red optical glass HB600 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 Belonging to a long wave pass filter, it can accurately cut off ultraviolet and visible light with wavelengths below 600nm Allow red light above 600nm and near-infrared light (up to 2500nm) to pass through Has angle insensitivity and maintains stable center wavelength at different incident angles 2. Optical performance Using a special element formula to achieve selective absorption, reaching a high cut-off depth at 600nm The transmittance in the red light region (600-700nm) can reach 85% -90% Good chemical stability, suitable for different working environments 3. Application advantages Specially suitable for photography filters, it can enhance the expressiveness of red and elevate the level of the image Accurate filterin…
