The main characteristics of the cutoff type golden optical glass JB470 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
Long wave pass filtering function: Accurately cuts off ultraviolet and visible light bands below 470nm, transmits spectra above 470nm (470-2500nm), and achieves steep cutoff edges.
Angle insensitivity: The neutral wavelength (470nm) 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 characteristics
Material and Craftsmanship: Gold colored optical glass doped with special elements, with uniform absorption characteristics.
Processing parameters: Sizes can be customized (up to 480mm x 480mm), with a thickness range of 0.15-50mm.
