    • 930 nm Dichroic Filter

    The 930 nm Dichroic Beamsplitter is a highperformance splitting element designed for fluorescence imaging, spectral analysis, machine vision, and research optical systems. Manufactured with precision multilayer dielectric coatings, it provides high transmission in the nearinfrared band (750-880 nm) and high reflection in the 980-1140 nm band at a 45° angle of incidence. The filter features a steep cutoff edge, excellent wavefront quality, and robust environmental reliability. It is particularly suited for applications requiring efficient beam separation and lowaberration imaging.

    Product features：Average transmission > 93 % in the 750–880 nm band；High reflection in the 980–1140 nm band；930 nm cut‑off wavelength；Optimised for 45° incidence optical paths；High environmental stability and long service life；Suitable for high‑power illumination systems

    Part Number：MP-DF-930

    Application area：Fluorescence microscopy | Confocal microscopy | Raman spectroscopy systems | Laser beam separation | Research and laboratory equipment
