Edmund Optics Inc. 400nm CWL, 50mm Dia. Hard Coated Bandpass Interference Filter NT84-793

High Transmission, Deep Blocking Broad Bandwidths Ideal for Imaging Applications Available in Visible and NIR Center Wavelengths Hard Coated Broadband Bandpass Interference Filters are ideal for eliminating unwanted background noise and enhancing the signal to noise ratio for a range of imaging applications including machine vision inspection, fluorescence microscopy, and a variety of biotech instrumentation. Unlike traditional filters, which require multiple substrates and coatings, these hard coated filters are fabricated using only a single substrate. The hard coated, single substrate fabrication offers deeper blocking, higher transmission, and steeper slopes than traditional coated filters.
