General purpose dichroic beamsplitters
Single-edge and multi-edge general purpose dichroic beamsplitters exhibit steep edges with very high and flat reflection and transmission bands. More complete reflection and transmission mean less stray light for lower background and improved signal-to-noise ratio.
RazorEdge dichroic beamsplitters
These dichroic beamsplitters exhibit unparalleled performance. Each filter reflects a standard laser line incident at 45° while efficiently passing the longer Raman-shifted wavelengths. They exhibit ultra-steep transition from reflection to transmission, far superior to anything else available on the open market. The guaranteed transition width of <1% of the laser wavelength for U-grade (regardless of polarisation) makes these filters a perfect match to the normal incidence RazorEdge long wave pass filters.
Image splitting dichroic beamsplitters
The image splitting dichroic beamsplitters give superb image quality for both reflected and transmitted light when separating beams of light by colour for simultaneous capture of multiple images. Their exceptional flatness virtually eliminates aberrations in the reflected beam for most common imaging systems.
Laser dichroic beamsplitters
The single edge and multi-edge laser dichroic beamsplitters are optimised for the most popular lasers used for fluorescence imaging. The reflection of the single-edge filter is guaranteed to be >98% (s-polarisation) and >94% (average polarisation) at the laser wavelengths, plus >93% average transmission and very low ripple over wide passbands out to 900 and even 1200nm. All standard Semrock filters have a 10-year guarantee and are available on a 30-day free trial.
48-Hour Cube Mounting Service.
If you purchase a filter or filter set and a compatible cube holder together, why not take advantage of our complimentary cube mounting service? The cube mounting option menu is available from the shopping basket menu after you have placed your filters and cube in your basket. Simply select the relevant option and we will mount it for you. Alternatively, feel free to contact us and let us know what you prefer.
