Edmund Optics Inc. 1100nm OD 2 Shortpass Filter 25mm Diameter NT47-592

Sharp Cut-off Wavelength High Transmission / Rejection Efficiency Precision Fused Silica Substrate Our TECHSPEC® Shortpass filters are designed to have a very sharp transition from transmission to reflection, making them extremely useful in a number of applications. Available in a variety of cut-off wavelengths, they are ideal for fluorescence applications, separating spectral orders, and creating custom, efficient bandpass filters when combined with our longpass filters. With an average transmission of 85% and a blocking optical density of 2.0, excellent contrast can be achieved in machine vision and gauging applications. A single layer AR coating on the back surface enhances the overall efficiency of each filter.Our shortpass filters are available in a number of kit configurations. Visible filter kits are available in 25nm increments (featuring 14 filters), or 50nm increments (featuring 7 filters). NIR Kits are available in 50nm increments (featuring 8 filters). All filter kits are available in 12.5, 25, and 50mm diameters.
