Iridian offers both assembled multi-zone filter arrays and patterned multi-zone optical filters (sometimes referred to as multi-spectral filters (MSF)) to address these growing needs. Features of Iridian&#8217;s MZF offerings include:<\/p>\n<ul>\n<li>Filter types:\n<ul>\n<li>Long-pass or short-pass filters (LPFs\/SPFs)<\/li>\n<li>Bandpass filters (BPFs)<\/li>\n<li>Notch filters<\/li>\n<li>Black absorbing coatings<\/li>\n<li>Anti-reflection coatings (ARs)<\/li>\n<li>High-reflectors (HR)<\/li>\n<\/ul>\n<\/li>\n<li>Wavelength range:\n<ul>\n<li>UV (300nm) to the long-wave infrared (LWIR 10 um)<\/li>\n<\/ul>\n<\/li>\n<li>Customization for size, spectral performance, and lay-out (number and size of zones)<\/li>\n<\/ul>\n<p>Many diverse applications benefit from the functionality offered by multi-zone filters. Iridian&#8217;s MZF technology has been deployed in applications such as:<\/p>\n<ul>\n<li>Multi-spectral imaging: <em>Remote sensing (environmental analysis, <a title=\"Space, Satellite and Astronomy\" href=\"https:\/\/iridian.com.cn\/en\/application-areas\/space-satellite-and-astronomy\/\">space, defense and security<\/a>)<\/em><\/li>\n<li>Multi-zone filter wheels: <em><a title=\"3D Cinema\" href=\"https:\/\/iridian.com.cn\/en\/specialty-filters\/3d-cinema-optical-filters-glasses\/\"><em>3D cinema<\/em><\/a> projection (&#8220;right-eye&#8221; and &#8220;left-eye&#8221; images)<\/em><\/li>\n<li>Order sorting for spectrometers or CCDs<\/li>\n<\/ul>\n<p>Iridian\u2019s new capabilities leverage our leading-edge technology to meet and exceed expectations for reliability and optical performance using our proven hard-dielectric coating technology. Iridian&#8217;s MZF meet durability and reliability requirements for space use (standard MIL specs) as well as customer defined requirements.<\/p>\n<h4>Assemblies<\/h4>\n<p>Our multi-zone filter assembly approach addresses needs in multi-spectral imaging applications requiring many bands, complex filter coatings, or with constraints on cost. In this approach coatings are deposited on separate substrates that are subsequently attached together using robust assembly methods. These assemblies can achieve zone-to-zone transitions of &lt; 100 \u03bcm and have been manufactured with as many as ten different spectral bands, turning single detectors into multi-spectral imaging devices.<\/p>\n<div class='one_fourth'>\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-386\" src=\"https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-1.jpg\" alt=\"MZF-1\" width=\"187\" height=\"186\" srcset=\"https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-1.jpg 187w, https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-1-150x150.jpg 150w, https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-1-100x100.jpg 100w\" sizes=\"(max-width: 187px) 100vw, 187px\" \/>\n\t\t\t\t<\/div>\n<div class='three_fourth et_column_last'>\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-387\" src=\"https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-2.png\" alt=\"MZF-2\" width=\"923\" height=\"429\" srcset=\"https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-2.png 923w, https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-2-480x223.png 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 923px, 100vw\" \/>\n\t\t\t\t<\/div><div class='clear'><\/div>\n<p>The image above shows a MZF with ten bandpass filters between 3um and 13 um developed under a subcontract from ABB Canada for the Space Technology Development Program of the Canadian Space Agency.<\/p>\n<h4>Patterning<\/h4>\n<p>For applications requiring a small transition zone or patterns not possible to achieve by assembly, Iridian&#8217;s patterned multi-zone filters are the perfect choice.<\/p>\n<p>Iridian&#8217;s in-house photo-lithography lab is housed a Class 1000 clean room capable of patterning up to 150 mm diameter wafers.
