The ability to offer spatially varying spectral performance on a single substrate can have many advantages for optical designers. 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\u2019s MZF offerings include:<\/p>\n
Many diverse applications benefit from the functionality offered by multi-zone filters. Iridian\u2019s MZF technology has been deployed in applications such as:<\/p>\n
Iridian\u2019s MZF capabilities leverage our leading-edge technology to meet and exceed expectations for reliability and optical performance using our proven hard-dielectric coating technology. Iridian\u2019s MZF meet durability and reliability requirements for space use (standard MIL specs) as well as customer defined requirements.<\/p>\n

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 < 100 \u03bcm and have been manufactured with as many as ten different spectral bands, turning single detectors into multi-spectral imaging devices.<\/p>\n
Assembled MZF\u2019s can include a patterned black coating<\/a><\/strong> to define the desired clear apertures of the individual zones and reduce scatter and stray light along the seams between zones and at the outer edges of the arrays.<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-1.jpg” title_text=”MZF-1″ align=”center” admin_label=”image 2″ _builder_version=”4.4.6″ width=”75%” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.4.8″ global_colors_info=”{}”]<\/p>\n 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 For applications requiring a small transition zone or patterns not possible to achieve by assembly, Iridian\u2019s patterned multi-zone filters are the perfect choice.<\/p>\n Iridian\u2019s in-house photo-lithography lab is housed in a Class 1000 clean room capable of patterning up to 150 mm diameter wafers. Multi-step patterning can be performed creating MZF\u2019s with as many as five different zones and zone-to-zone transitions of as little as 20 \u03bcm.<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/iridian.com.cn\/wp-content\/uploads\/2014\/10\/MZF-3.jpg” align=”center” _builder_version=”4.4.3″ global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.4.8″ global_colors_info=”{}”]<\/p>\n Patterned MZF\u2019s can include black coating transition zones to isolate the separate spectral bands, reducing the potential for cross-talk at the detector.<\/p>\n [\/et_pb_text][et_pb_text disabled_on=”on|on|on” _builder_version=”4.4.3″ disabled=”on” global_colors_info=”{}”]<\/p>\n Some Applications for our Multi-Zone Filters include:\u00a0<\/strong><\/p>\n <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ disabled_on=”on|on|on” _builder_version=”4.3.4″ custom_margin=”||75px||false|false” disabled=”on” global_colors_info=”{}”][et_pb_row column_structure=”1_4,3_4″ _builder_version=”4.3.4″ global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.3.4″ global_colors_info=”{}”][\/et_pb_column][et_pb_column type=”3_4″ _builder_version=”4.3.4″ global_colors_info=”{}”][et_pb_button button_url=”\/rfq\/” url_new_window=”on” button_text=”@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF90aXRsZSIsInNldHRpbmdzIjp7ImJlZm9yZSI6IkNvbnRhY3QgVXMgZm9yIFlvdXIgIiwiYWZ0ZXIiOiIgUmVxdWlyZW1lbnRzIn19@” button_alignment=”left” admin_label=”CTA button- Contact us” _builder_version=”4.3.4″ _dynamic_attributes=”button_text” global_colors_info=”{}”][\/et_pb_button][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" \u00a0 The ability to offer spatially varying spectral performance on a single substrate can have many advantages for optical designers.
