Fluorescence Filter (Narrow Bandpass filter) Description

Narrow bandpass filter or fluorescence filter is used to isolate and transmit a specified narrow wavelength and reflect all other incident wavelengths. Shapeoptics fabricates fluorescence filters ( Narrow band pass filter) which are suitable for single and multiple microscopy application, including GFP FRET, photons, quantum dots ,pinkel, contrast imaging and other technologies.

The high transmission of the fluorescence filters (Narrow band pass filter) guarantees the brightest possible images, while the deep blocking ensures no unwanted light gets to the detector. This ensures images will be brighter and will have much greater signal-to-noise.
