How to Choose

Use longpass filters when longer wavelengths should pass and shorter wavelengths should be blocked. Use shortpass filters for the reverse. Confirm the edge wavelength, transition slope, blocking range, AOI, and whether the filter will be paired with a bandpass filter.

Longpass & Shortpass Filters

OPTOStokes longpass and shortpass filters provide sharp edge transitions for wavelength separation in fluorescence microscopy, Raman spectroscopy, and optical instrumentation. Longpass filters transmit wavelengths longer than the cut-on while blocking shorter wavelengths; shortpass filters do the reverse. They combine well with bandpass filters when precise spectral selectivity is required.

Related Engineering Notes

Edge steepness and transition width

Longpass and shortpass filters are often selected by edge position, but transition width and blocking depth determine real system performance.

Combining edge filters

A longpass and shortpass pair can define a custom passband when a standard bandpass option is not available.

Detector protection

Use edge filters to suppress unwanted source energy before it reaches sensitive detectors, especially in broadband or high-power systems.

FAQ

What is the difference between longpass and shortpass filters?

A longpass filter transmits wavelengths longer than its edge; a shortpass filter transmits wavelengths shorter than its edge.

What does cut-on or cut-off wavelength mean?

It is the edge wavelength where the filter transitions between blocking and transmission.

Can edge filters be combined with bandpass filters?

Yes. Edge filters are often combined with bandpass filters to improve blocking or shape a more specific spectral window.
