Product Family Description

Our TECHSPEC® Dichroic Filters (sometimes referred to as dichroic plate beamsplitters or dichroic mirrors) feature broad, flat transmission and reflection ranges with an ultra-steep slope between them. These attributes make them ideal for fluorescence imaging or spectral sorting applications, including DNA sequencing and polymerase chain reaction (PCR) diagnostic instruments. They are a perfect complement to our TECHSPEC® Fluorescence Bandpass Filters. The 25.2 x 35.6mm size will fit into most common Nikon, Zeiss, and Olympus fluorescence microscopes, whereas the other sizes are well suited to benchtop setups or OEM instrumentation requiring beam separation, beam combination, or multi-spectral detection.
