Introduction: | Long Pass Filters are useful for isolating wavelengths from different regions of the spectrum, allowing high transmission above the cut-on wavelength (in the pass band), and high reflection below the cut-on wavelength (in the blocking band). The durable dielectric coating of Long Pass Filters makes them instrumental in many industrial and Research & Development applications, due to the rejection band optical density of 3.0 and >85% transmission above the cut-on wavelength.
Long Pass Filters characteristics may be customized upon customers' request |
