{"id":276,"count":61,"description":"Explore our precision-engineered longpass filters, designed to provide exceptional spectral control by transmitting long-wavelength light while effectively blocking shorter wavelengths. Built on advanced multi-layer dielectric coating technology, our longpass filters feature remarkably steep transition edges, ensuring a rapid and highly accurate shift from the blocking region to the high-transmission passband. We guarantee absolute out-of-band blocking depths, with Optical Density (OD) values representing true absolute measurements for superior background noise rejection. Coupled with exceptionally high peak transmission rates, our filters maximize signal throughput and enhance the signal-to-noise ratio in your optical systems. These high-performance components are widely utilized across a diverse range of cutting-edge applications, including fluorescence microscopy, Raman spectroscopy, machine vision, LIDAR, laser line separation, and advanced scientific research. Whether you require standard configurations or customized spectral solutions, our longpass filters deliver the uncompromising reliability and optical clarity necessary to drive your most critical experiments and industrial applications forward.","link":"https:\/\/www.signoraoptics.com\/?product_cat=longpass-filters","name":"Longpass Filters","slug":"longpass-filters","taxonomy":"product_cat","parent":18,"meta":[],"_links":{"self":[{"href":"https:\/\/www.signoraoptics.com\/index.php?rest_route=\/wp\/v2\/product_cat\/276","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.signoraoptics.com\/index.php?rest_route=\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/www.signoraoptics.com\/index.php?rest_route=\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/www.signoraoptics.com\/index.php?rest_route=\/wp\/v2\/product_cat\/18"}],"wp:post_type":[{"href":"https:\/\/www.signoraoptics.com\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct&product_cat=276"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
