With 400W or 500W lasers, the lens barrel may overheat—thus not recommended for high-power applications. The lens features a highly reflective coating optimized for wavelengths between 900–1000 nm, ideal for common laser wavelengths such as 915, 974, and 976 nm. It is also designed to support coaxial red and green light, significantly improving transmission efficiency.  \u003c\/p\u003e\n\u003cp\u003eLens base specifications: M22×0.75 (central aperture diameter 5mm; mounting screw hole with horizontal slot suitable for 2mm screws).  \u003c\/p\u003e\n\u003cp\u003eNote: The markings on the lens do not represent exact distances but serve as reference marks to remember approximate focusing positions during adjustment. Since each laser source has different beam divergence characteristics, these marks help ensure consistent alignment. When equipped with coaxial red or green light, adjusting spot size becomes much easier.\u003c\/p\u003e","brand":"Gearlair","offers":[{"title":"Default Title","offer_id":49993119891679,"sku":null,"price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0803\/3632\/2783\/files\/IMG_8862.jpg?v=1780540307","url":"https:\/\/gearlair.com\/products\/laser-pumped-telescopic-pull-out-lens-10x-laser-beam-expander-nbsp","provider":"Gearlair","version":"1.0","type":"link"}
