UV Bandpass Filters
193-400nm
For ultraviolet wavelength selection in UV detection, spectroscopy, and optical measurement.
VIS Bandpass Filters
400–700nm
For visible wavelength selection in imaging, fluorescence, inspection, and optical measurement.
NIR Bandpass Filters
700–1100nm
For near-infrared sensing, machine vision, laser detection, and optical systems.
SWIR Bandpass Filters
1100–2500nm
For extended infrared wavelength selection and optical sensing applications.
1-5nm FWHM
For narrow spectral isolation where high selectivity is required.
Laser-line cleanup, spectroscopy, narrow wavelength detection.
10nm FWHM
A common choice for laser, fluorescence, sensing, and optical measurement.
532nm, 650nm, 850nm, 940nm, and other common wavelength filters.
11-39nm FWHM
Balanced bandwidth for selectivity and signal throughput.
Machine vision, fluorescence emission, LED-based inspection.
40nm+ FWHM
For broader passbands where higher signal collection is more important than narrow isolation.
Broadband illumination, imaging, and low-light optical systems.
Fluorescence
Select excitation or emission wavelength bands for fluorescence imaging and detection.
Laser Systems
Isolate common laser wavelengths and reduce unwanted background light.
