{"product_id":"1x-3x","title":"LBTEK High Precision Zoom Beam Expander 1X-3X UVFS Galilean 355\/532\/1064nm","description":"\u003cp\u003eLBTEK high precision zoom beam expanders mainly consist of 3 groups of UVFS lenses integrated in a mechanical housing with a Galilean design. The relative displacement of lens groups 1 and 2 changes the magnification, while the relative displacement of lens groups 2 and 3 changes the divergence. The input end is marked with position indicators for each magnification, and the output end is marked with position and distance indicators. For collimated incident light, when the input and output ends are rotated so that the position indicators match, a collimated expanded beam at the corresponding magnification is obtained. Standard LBTEK high precision zoom beam expanders offer magnifications of 1-3X, 1-4X and 2-10X, and wavelengths of 355 nm, 532 nm and 1064 nm. They are designed for diffraction-limited performance with no internal focus, making them ideal for high-power laser processing. In addition, LBTEK supports customization of different wavelengths and magnifications. Please contact LBTEK technical support for details.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eOptical Glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisible Light Transmittance\u003c\/th\u003e\n\u003ctd\u003e90%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFilter Size\u003c\/th\u003e\n\u003ctd\u003e25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"LBTEK","offers":[{"title":"Default Title","offer_id":46735096938682,"sku":"1X-3X","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/1123\/6538\/files\/708b24666323949350ca0a6b6b28886a.jpg?v=1789986252","url":"https:\/\/opticssupplypro.com\/products\/1x-3x","provider":"LUMINA Optics","version":"1.0","type":"link"}
