Choose from essential filter types used in life science and diagnostic instruments:
Single Bandpass Filters — Define individual fluorescence channels with tight spectral control.
Multiband Bandpass Filters — Support multiplexed detection in compact optical paths.
Longpass Filters — Pass emission while blocking excitation and stray light.
Shortpass Filters — Pass shorter wavelengths for excitation control or order sorting.
Excitation Filters - Shape and clean excitation light for fluorescence-based assays.
Emission Filters - Isolate fluorescence signals at the detector.
Dichroic Beamsplitters — Separate excitation and detection paths in multi-channel systems.
Multiband Dichroic Beamsplitters - Enable efficient splitting across multiple fluorescence channels.
Notch Rejection Filters — Block laser lines where additional suppression is required.
Neutral Density Filters — Control intensity without altering spectral shape.
