{"id":68,"count":45,"description":"Edge pass filters are use to isolate one band of wavelengths from another by either reflecting or transmitting one band while transmitting or reflecting the second band.  In the case of Raman spectroscopy, edge pass filters are used to separate the excitation source wavelength from the emission wavelengths.\r\n\r\nIridian supplies both short and long pass filters for Raman Spectroscopy which are ultra-steep (have a sharper transition) compared to standard edge pass filters.  \r\n\r\nIridian also offers customized spectroscopic edge pass filters for a range of wavelengths (UV, visible and SWIR \u2013 400 to 1400 nm) and for various angles of incidence (AoI).  Extra wide wavelength blocking is also possible.\r\n\r\nFor further information on the Iridian\u2019s Raman filters, please click on the following:\r\n\r\n\u00a0\r\n\r\n[nice-button link=\"\/technical-resources\/optical-filter-tutorials\/edge-filters-raman-spectroscopy\/\"]Raman Spectroscopy Tutorial[\/nice-button]","link":"https:\/\/iridian.jp\/en\/product-category\/spectroscopic\/edge-pass-filters\/","name":"Edge Filters","slug":"edge-pass-filters","taxonomy":"product_cat","parent":40,"meta":[],"menu_order":13,"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.7 (Yoast SEO v28.7) -
