Longpass Filter |
|
Feature
|
|
|
Longpass filters are designed to have a sharp transition from reflection to transmission, making them ideal for various applications. Available in a variety of cut-on wavelengths, these filters are designed for fluorescence and order sorting applications. Eliminate stray light by creating custom bandpass filters when combined with Shortpass Filters. A single layer AR coating on the back surface enhances the overall efficiency of each filter. High performance longpass filter (cut-off slope <1%, rejection OD ≥4, transmission in pass band ≥90%) is available upon request. |
