308nm Notch Optical Filter
The 308nm Notch Optical Filter is engineered for precision applications requiring targeted UV light suppression. With >90% transmittance across 250-1200nm and OD>6 blocking at 308nm±5nm, it excels in medical excimer laser systems (e.g., 308nm XeCl lasers for psoriasis and vitiligo therapy) by isolating therapeutic wavelengths while protecting sensitive detectors .Ideal for Raman spectroscopy and industrial UV-sensitive instruments, its hard-coated dielectric layers withstand high-power laser exposure (up to 1J/cm²).Customizable bandwidths (±5nm-±20nm) and fused silica substrates ensure compatibility with diverse optical configurations.
