In Raman spectroscopy, this allows observation of Stokes (long wavelengths) and Anti-Stokes (short wavelengths) scattered light while blocking the laser line. High transmittance in the passband and deep blocking at the excitation laser line (OD &gt; 6) provides more signal with less background. We offer notch filters with a CWL from 442nm to 1550nm and beyond.<\/p>\n<p>Iridian specializes in providing custom notch filter solutions for a wide range of applications. Our in house design software, multiple process options and 20 years\u2019 experience dealing with a wide range of applications allow you to optimize notch filter performance and cost for your needs. Our filters are all deposited using energetic sputtering, ensuring a hard durable, environmentally stable coating. The resulting filters also have exceptionally high transmittance levels and blocking from the visible to the MWIR (300nm to 10um). We partner with you from prototype to volume production to support you and the success of your business.<\/p>\n<\/div>\n<\/div>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/iridian.jp\/wp-content\/uploads\/2020\/04\/633nm-Notch.png&#8221; title_text=&#8221;633nm Notch&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.20.2&#8243; _module_preset=&#8221;default&#8221; hover_enabled=&#8221;0&#8243; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<p>Iridian\u2019s superior notch filters provide:<\/p>\n<ul>\n<li>Steep roll-off<\/li>\n<li>High transmission (&gt; 90%) and high blocking (&gt; OD6)<\/li>\n<li>Narrow notch width 10-70 nm FWHM<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>Applications for our notch filters include:<\/p>\n<p><u><a href=\"https:\/\/iridian.jp\/en\/product-category\/raman-filters\/raman-notch-filters\/\"><strong>Raman Spectroscopy<\/strong><\/a><\/u><\/p>\n<ul>\n<li><strong><em>Your application <\/em><\/strong><strong>\u2013 OEM and custom<\/strong><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>We also offer a wide range of standard filters available for immediate <a href=\"https:\/\/iridian.jp\/en\/products\/\">purchase online<\/a>.<\/p>\n<p><a href=\"https:\/\/iridian.jp\/en\/products\/\"><strong>View our online catalog<\/strong><\/a><\/p>\n<p><a href=\"https:\/\/iridian.jp\/en\/company-facts\/contact-us\/\"><strong>Contact us<\/strong> <\/a>for your notch filter requirements.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Notch filters are used to block a narrow range of wavelengths.
