This 1654nm narrow band reflective infrared optical filter is engineered
to precisely transmit the target infrared wavelength while reflecting
out-of-band light, ensuring high spectral selectivity and superior signal purity.
Fabricated from optical-grade glass and coated with advanced
multilayer thin-film technology, the filter delivers stable wavelength accuracy,
high reflection efficiency, and long-term optical reliability, even in demanding environments.
• Optical Glass Substrate, providing excellent flatness and low optical distortion
This filter is ideal for infrared laser systems, optical sensing,
spectroscopy, optical communication, and scientific instrumentation,
where precise wavelength control and high reflection performance are essential.
