Product Description

ISO-Certified Optics Factory Producing High-Volume Custom Band-Pass Filters at Wholesale Prices – Direct From Manufacturer
Product Description
A band-pass filter is a precision optical component designed to selectively transmit light within a specific wavelength range, widely used in optical detection, spectral analysis, laser systems, biomedical imaging (e.g., fluorescence microscopy), astronomical observation, and other fields. It is typically fabricated by depositing multiple dielectric films on a substrate (such as optical glass or quartz), leveraging the principle of light interference to achieve high transmittance in the target band and high blocking in other bands. Its performance is determined by the central wavelength, bandwidth (Full Width at Half Maximum, FWHM), and peak transmittance: the central wavelength defines the center of the passband, the bandwidth determines the width of the allowed wavelength range, and the peak transmittance reflects the efficiency of light transmission. Depending on application requirements, band-pass filters can be designed as narrow-band (bandwidth <10nm) or broad-band (bandwidth >50nm), with customizable parameters such as size and blocking depth to fit different devices.
