Optical Filters

From high performance fluorescence filters for DNA analyzers to notch filters for laser safety eyewear, our optical filters provide the full spectrum of solutions for managing light. Stabilife^® optical filters and coatings use a patented process for the deposition of metal oxide thin film using sputtered Hybrid Plasma Deposition (HPD). This process yields highly dense, thin film coatings with extraordinary hardness, abrasion resistance, and adhesion to the substrate. Expanding our portfolio, we offer advanced ODiate^® Fluorescence Filter Sets, single- and dual-band configurations comprising eight high-performance filters engineered for brighter, higher-contrast imaging. Their high-transmission, steep-edge, deep-OD thin-film coatings deliver exceptional signal-to-noise for microscopy, flow cytometry, and PCR systems, supporting simultaneous multi-fluorophore imaging with fewer components. Complementing these, our ODiate^® Raman Longpass Filters provide outstanding sensitivity for low-wavenumber Raman detection, featuring high transmission, ≥OD6 Rayleigh blocking, and ultra-sharp edge transitions. Designed with durable hard-coated thin films for long-term stability and laser-damage resistance, they are ideal for confocal microscopy, portable Raman instruments, industrial probes, and OEM spectrographs, supporting key Raman laser lines from 488–785 nm while enabling clearer spectra and simplified optical design.
