CVI offers a full line of Holographic Notch Filters. These filters are different from conventional interference
filters because they are manufactured by capturing interference patterns formed by two mutually coherent
laser beams. This technique creates a filter with very high rejection at the center wavelength and a very
narrow bandwidth. These Holographic Notch Filters have a high damage threshold and may just be the
perfect choice for your imaging applications. We offer many standard options in center wavelength and
size. For custom wavelengths and sizes please call CVI for more information. |  |
