The sensor&#8217;s compact design enables long-term stable adjustment and placement, even in confined spaces. The interferometer&#8217;s basic principle is based on the SP 5000 DI series, and enables sub-nanometer length resolutions. Measurements over several meters are easily possible thanks to the use of SP series reflectors.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<div class=\"ctadiv\"><a class=\"cta\" href=\"https:\/\/www.trioptics.fr\/en\/contact\/\">Contact us for a quote<\/a><\/div>\n<div class=\"tlchgmt\">\n<p class=\"titdoc\"><Span class=\"tittel\">Download data sheet<\/span><\/p>\n<p><a class=\"doctel\" href=\"https:\/\/www.trioptics.fr\/wp-content\/uploads\/2024\/10\/BROCHURE-SIOS.pdf\" target=\"_blank\" rel=\"noopener\"><span class=\"nomtel\">BROCHURE SIOS.pdf<\/span><\/a><\/p>\n<p><a class=\"doctel\" href=\"https:\/\/www.trioptics.fr\/wp-content\/uploads\/2024\/09\/datasheet-differential-interferometer-SP-DI-1-1.pdf\" target=\"_blank\" rel=\"noopener\">Download datasheet <span class=\"nomtel\">SP 5000 DI\/F_engl_kl.pdf<\/span><\/a><\/p>\n<p><a class=\"doctel\" href=\"https:\/\/www.trioptics.fr\/wp-content\/uploads\/2024\/09\/differential-interferometer-SP-DI-engl-flyer.pdf\" target=\"_blank\" rel=\"noopener\">Flyer <span class=\"nomtel\">SP 5000 DI\/F_engl_kl.pdf<\/span><\/a><\/p>\n<p><a class=\"doctel\" href=\"https:\/\/www.trioptics.fr\/wp-content\/uploads\/2024\/09\/masskizze-SP-5000-DI-F-A035977-beam-spacing-14mm.pdf\" target=\"_blank\" rel=\"noopener\">Product dimensions <span class=\"nomtel\">SP 5000 DI\/F_engl_kl.pdf<\/span><\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Differential interferometer for servo loops<\/p>\n","protected":false},"featured_media":39722,"template":"","meta":{"rs_blank_template":"","rs_page_bg_color":"","slide_template_v7":""},"product_brand":[],"product_cat":[1576],"product_tag":[],"class_list":["post-41322","product","type-product","status-publish","has-post-thumbnail","product_cat-length-measurement-systems","first","instock","shipping-taxable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>SP 5000 DI\/F Differential Laser Interferometer<\/title>\n<meta name=\"description\" content=\"TRIOPTICS distributes high-precision optical equipment for industry and research, including SP 5000 DI\/F Differential Laser Interferometer.
