Bandpass filter glass DBT435

The bandpass filter glass DBT435 is an optical component used for selective transmission in a specific wavelength range (such as around 435nm), with its core function being to allow light in the target wavelength band (such as 435nm) to pass through while cutting off light of other wavelengths. Here is a summary of its key information:(Bandpass Filter Optical Glass,Laser rangefinder optical glass,Security monitoring optical filter,) 1. Technical characteristics Center wavelength: 435nm (typical application is blue light cutoff or specific band transmission). Bandwidth: It needs to be customized according to specific needs, and the common narrowband filter bandwidth is 10-50nm. Material: Typically, optical glass substrates (such as Schott CB series colored glass) or coated glass are used. 2. Manufacturing process Absorption type: Achieving bandpass effect through the intrinsic absorption characteristics of colored glass (such as CB535, CB550). Interference type: Coating multiple layer…
