1175nm CWL, 25mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter

Product Details High Transmission, Deep Blocking Broad Bandwidths Ideal for Imaging Applications Available in VIS and IR Center Wavelengths Hard Coated OD 4.0 10nm and 25nm Bandpass Filters Also Available TECHSPEC Hard Coated OD 4.0 50nm Bandpass Filters are ideal for imaging applications, including machine vision inspection, fluorescence microscopy, and a variety of biotech instrumentation. These bandpass filters eliminate unwanted background noise and enhance the signal-to-noise ratio within imaging applications. Unlike traditional filters, these hard coated filters are fabricated using only a single substrate. TECHSPEC Hard Coated OD 4.0 50nm Bandpass Filters offer deeper blocking, higher transmission, and steeper slopes than traditional coated filters. Hard Coated OD 4.0 10nm and 25nm are also available. Note: These filters are optimized for high spectral performance rather than high Laser Induced Damage Thresholds (LIDT). A typical LIDT for these filters is 1 J/cm 2 @ 532nm, 10ns. Please contact us if you require a filter with a higher LIDT value.
