Cutoff Type Golden Glass JB450

The main characteristics of the cutoff type golden optical glass JB450 are as follows: (Cut off orange glass,Cut off red glass,Cut off golden glass,Cut off infrared transmission visible absorption glass) 1. Optical characteristics Wavelength cut-off function: Accurately cut-off the ultraviolet and visible light bands below 450nm, transmitting spectra above 450nm, it is an economical long wave pass filter. Angle insensitivity: The neutral wavelength (cutoff wavelength) remains unchanged for beams with different incident angles, making it suitable for multi angle optical systems. Relationship between transmittance and thickness: Increasing thickness will slightly reduce transmittance, but can increase the cutoff depth. 2. Physical and material properties Material: Gold colored optical glass doped with special elements, uniformly absorbing short wave spectra. Surface treatment: Supports double-sided polishing, with a smoothness of 60/40 standard and customizable thickness (0.2-120mm). T…
