Products Description
BP5300nm MWIR Bandpass Filter | 260nm FWHM, OD2 Blocking, 5300nm CWL

The OPTOStokes BP5300nm is a precision mid-wave infrared bandpass filter engineered for accurate spectral selection in non-contact temperature measurement and thermal sensing systems. Fabricated with advanced hard dielectric thin-film coating technology, this filter delivers consistent transmission greater than 80% at the 5300nm center wavelength, with a well-defined 260nm ±20nm full width at half maximum for targeted passband control. As part of our extensive in-stock bandpass filters portfolio, it provides reliable optical density greater than 2 out-of-band blocking across 2000–11000nm, ensuring clean signal isolation for demanding MWIR detection applications. Built to world-class quality standards, it delivers stable long-term performance in continuous industrial operating environments.

Typical Applications
This 5300nm MWIR bandpass filter is optimized for mid-temperature range non-contact infrared temperature measurement and related thermal detection scenarios. It is widely deployed in industrial process monitoring, infrared imaging systems, industrial inspection equipment, and thermal sensing modules. Its precise passband control and strong out-of-band rejection effectively filter out background thermal noise and stray radiation, improving measurement accuracy and signal-to-noise ratio for non-contact thermometry and mid-infrared analytical detection systems.
