Shortpass dichroic mirrors transmit light beams below the cut-off wavelength while reflecting those above the cut-off wavelength with high transmission and high reflection characteristics. Our dichroic mirrors offer 14 cut-off wavelength options: 425 nm, 490 nm, 505 nm, 550 nm, 605 nm, 638 nm, 650 nm, 780 nm, 805 nm, 950 nm, 1000 nm, 1180 nm, 1500 nm, and 1800 nm, with average transmission and reflection rates exceeding 90% within the specified wavelength ranges. LBTEK provides four size options: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm, and 36.0 mm × 25.0 mm. A dichroic mirror has a filter coating on one surface and an antireflection coating on the other. The arrow points to the filter-coated surface. LBTEK also offers longpass dichroic  mirrors, which transmit light above the cut-on wavelength while reflecting light below it. In addition to standard dichroic mirrors, LBTEK also offers a variety of custom dichroic mirrors. Please contact LBTEK Technical Support for special requirements.\u003c\/p\u003e\n\u003ch3\u003eShort-pass dichroic mirror, elliptical\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSubstrate Material: UVFS\u003c\/li\u003e\n\u003cli\u003eElliptical\u003c\/li\u003e\n\u003cli\u003eApplication: Filtering and Beam Splitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eLBTEK dichroic mirrors can separate light beams based on wavelength. Shortpass dichroic mirrors transmit light beams below the cutoff wavelength while reflecting those above it, featuring high transmission and high reflection characteristics. Currently, the elliptical dichroic mirror has a cutoff wavelength of 550 nm, achieving over 90% transmittance in the specified band range (390-533 nm) and over 90% reflectance in the range (565-800 nm). One surface of the dichroic mirror is coated with a filter film, and the other side is coated with an anti-reflection film. It is recommended to have the light incident from the filter film side (the side arrow points to the filter film-coated surface).\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47517740007578,"sku":"DME38×57-550SP-SP","price":690.78,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/DME38_C3_9757-550SP-SP-FmTMgUUyLyxjNOcW15Yh6yV0OnuG.jpg?v=1772666436","url":"https:\/\/waveqvanta.com\/products\/shortpass-dichroic-mirrors-dme38-57-550sp-sp","provider":"WaveQuanta","version":"1.0","type":"link"}
