Product Family Description

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 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.
