1000nm, 12.5mm Diameter, Dichroic Longpass Filter

Product Details Ideal for Fluorescence or Multispectral Imaging Sharp Cut-On Wavelength Broad Transmission and Reflection Ranges Our TECHSPEC Dichroic Longpass Filters are designed for a 45° angle of incidence. The rejected light is reflected at 90°, making these filters ideal for use in fluorescence applications or as spectral beamsplitters . These hard coated filters feature low polarization dependence, broad spectral ranges, and a precision fused silica substrate. Reflection and transmission curves are available to easily integrate TECHSPEC Dichroic Longpass Filters into any application. Note: The chevron on the edge of the filter points towards surface S1 with the primary filter coating on which the light should be incident. Hard coatings are used to increase durability while maintaining performance. The hard coating provides Dichroic Longpass Filters with high resistance to humidity, temperature, and abrasion, while also reducing the risk of damage when being handled.
