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.
