Optical 900nm Bandpass Filter, Glass Substrate, 40nm Bandwidth

This product is a 900nm narrow bandpass filter manufactured

on a high-quality optical glass substrate with

multi-layer interference reflective coating.

It provides high transmission at the 900nm

center wavelength while effectively reflecting

and blocking out-of-band light,

ensuring excellent spectral selectivity.

With a 40nm bandwidth (FWHM),

the filter offers stable optical performance,

sharp cutoff characteristics, and high wavelength consistency.

It is widely used in infrared imaging, optical inspection,

machine vision, medical devices, and scientific instruments.

Standard and custom sizes are available upon request.
