Description
The BH-A16 Red Reflect Mirror (RRM) is a color-selective dichroic designed to reflect red light while efficiently transmitting blue and green wavelengths. With peak transmission of 97 % at 508 nm and sustained >80 % transmission across the 409-550 nm blue-green band, the RRM enables simultaneous red laser excitation with blue-green detection. Red blocking remains exceptional (\<5 % across 600-700 nm: 2.6 %) while maintaining high blue (92 %) and moderate green (58 %) transmission. The RRM is essential for confocal systems combining red laser excitation with GFP and DAPI detection, or for flow cytometry requiring red laser separation.
Key Advantages
- Peak Blue-Green Transmission - 97 % transmission at 508 nm with Blue: 92 %, Green: 58 % enables efficient detection of blue and green fluorophores excited separately.
- Complete Red Reflection - 2.6 % average transmission across 600-700 nm reflects red laser excitation and red fluorophore signals to alternative detection pathways.
- Broadband Blue-Green Pass-Band - 141 nm transmission bandwidth (409-550 nm) captures full blue and green spectral range for multi-parameter detection.
- Hard-Oxide Ion-Assisted Coating - Multilayer hard-oxide design maintains dichroic performance under red laser illumination and environmental thermal stress.
- Custom Format Flexibility - Round, square, and free-form geometries from 5-450 mm with Borofloat, soda-lime, Schott D263 T, and Corning Eagle XG substrate options.
Typical Applications
- Red-Excited Confocal Microscopy - Primary dichroic for 633-680 nm red laser excitation, reflecting excitation while transmitting blue DAPI and green GFP emissions.
- Dual-Color Flow Cytometry - Separates red laser excitation from blue-green detection, enabling efficient simultaneous measurement of DAPI and green fluorophores.
- Multi-Laser Confocal Systems - Combines red excitation pathway with blue-green detection from independently excited DAPI and GFP channels.
- Selective Excitation Microscopy - Isolates red laser excitation of far-red dyes from blue and green autofluorescence, improving signal contrast.
- Raman and Reflectance Spectroscopy - Reflects red laser excitation while collecting blue-green Raman Stokes shifts and reflectance signatures simultaneously.
