Camera & imaging
Control unwanted wavelengths, exposure and reflections before light reaches the sensor.
Selected illumination
Bandpass Filters
Isolate the useful illumination band when the camera should detect a specific wavelength range.
View Bandpass Filters →Exposure control
Neutral Density Filters
Reduce incident light when illumination is too strong for the desired exposure.

Anti-Reflection Coatings
Reduce surface reflections in the optical path. AR2S-VIS-01 provides a published visible-range sample reference.
View Anti-Reflection Coatings →Product-family selection guide. The final model depends on source spectrum, sensor response, working angle and required rejection.

PCB & machine inspection
Match the filter to the inspection light and the feature you need to distinguish.
LED inspection
Bandpass Filters
Pass the inspection source band while reducing out-of-band ambient light.
View Bandpass Filters →Short-wavelength selection
Shortpass Filters
Favor shorter wavelengths when longer-wavelength light interferes with the inspection channel.
View Shortpass Filters →Long-wavelength selection
Longpass Filters
Favor longer wavelengths when shorter-wavelength background needs to be rejected.
View Longpass Filters →Bright or reflective targets
Neutral Density Filters
Control light intensity at the detector while preserving the selected spectral region.
View Neutral Density Filters →Product-family selection guide. The final model depends on source spectrum, sensor response, working angle and required rejection.
APPLICATION / PRODUCT SELECTION
Microscopy & laboratory
Separate useful spectral signals from excitation light and background.
Excitation / detection channels
Bandpass Filters
Select an excitation or detection band; confirm bandwidth and blocking for the instrument.
View Bandpass Filters →Unwanted spectral lines
Notch Filters
Reject a narrow unwanted band while retaining wavelengths on either side.
View Notch Filters →Spectral separation
Longpass Filters
Pass longer wavelengths when shorter-wavelength excitation or background must be suppressed.
View Longpass Filters →Multiple optical paths
Beam Splitters
Divide light between illumination, observation or measurement paths. Confirm ratio, wavelength and working angle.
View Beam Splitters →Product-family selection guide. The final model depends on source spectrum, sensor response, working angle and required rejection.
APPLICATION / PRODUCT SELECTION
IR surveillance
Select the camera channel around illumination wavelength and day/night operation.
Infrared imaging
IR Transmission Filters
Pass the specified infrared region and reject unwanted shorter wavelengths, where supported by the selected model.
View IR Transmission Filters →Active IR illumination
Bandpass Filters
Select a band around the IR illuminator to reduce out-of-band background.
View Bandpass Filters →Daytime color imaging
IR Cut-off Filters
Limit infrared in the daytime visible channel; an IR cut-off filter must not block the desired nighttime IR path.

Anti-Reflection Coatings
Reduce window reflections with a coating designed for the required IR range. Visible AR2S-VIS-01 data do not establish IR performance.
View Anti-Reflection Coatings →Product-family selection guide. The final model depends on source spectrum, sensor response, working angle and required rejection.
