283nm Notch Optical Filter

The 283nm Notch Optical Filter is a high-performance band-rejection filter designed to block 283nm ultraviolet light with ultra-high precision. Featuring an optical density (OD) of >6 at the notch wavelength, it ensures >90% transmission across a broad spectrum (250-1200nm), minimizing energy loss. Ideal for laser-based Raman spectroscopy, fluorescence imaging, and UV-sensitive medical systems, this filter employs hard-coated multilayer dielectric technology for durability and high laser damage threshold (up to 1J/cm²). Customizable bandwidth (±5nm to ±20nm) and substrate options (fused silica/glass) are available for specialized applications.
