Shortpass Filter
Short pass filters are used to transmit wavelengths shorter than the cut-off wavelength of the filter.
Short pass filters are commonly use in life science applications including fluorescence microscopy or for integration into a variety of instrumentation.
These optical filters can also be used as hot mirrors to minimize unwanted heat caused by infrared radiation.
DELN offers a variety of short pass filters with high blocking and maximized transmission.
Other Cut-On Wavelength and specifications are available upon request.
