405nm Bandpass Optical Filter

405nm Bandpass Optical Filter Designed for applications demanding stringent spectral control, our 405 nm Bandpass Filter delivers high transmission (≥45%) along with deep out-of-band blocking (OD≥5), enabling effective isolation of specific wavelengths in biochemical analysis, fluorescence detection, and laser systems. This filter is specifically engineered to eliminate interference from ultraviolet (UV) and infrared (IR) radiation, thereby preserving signal integrity in sensitive optical environments.Key Features & Technical Specifications Central Wavelength: 405 nm ±2 nm, suitable for violet laser or LED cleanup, as well as narrowband detection in fluorescence microscopy and enzymatic assays. Bandwidth: 10 nm FWHM, providing sharp spectral edges that minimize crosstalk and improve resolution. Blocking Performance: OD≥5 suppression across 200–1100 nm, ensuring effective isolation of the 405 nm band from ambient light and harmonic interference. Substrate: High-performance optical…
