This is caused by the reflection of a laser at two black planar glass mirrors which are offset by a small angle of a few minutes. The laser, mirrors and the optical projector are all mounted on a metal base. One mirror is fixed and the other is adjustable to change the angle of inclination. A projection screen, a ground glass screen with scaled crosshairs and a battery box are also included.\u003cbr\u003e\u003cbr\u003eSpecifications:\u003cbr\u003eDiode Laser: class II\u003cbr\u003eOutput power: \u0026lt; 1 mW\u003cbr\u003eWavelength: 635 nm\u003cbr\u003eOperating voltage: 3 V DC\u003cbr\u003eBattery-box: requires 2x 1.5 V LR6 (MN1500, AA) batteries (batteries not included)\u003cbr\u003e\u003cbr\u003eDimensions:\u003cbr\u003eMetal base: 400 x 75 x 85 mm³\u003cbr\u003eScreens: 150 x 90 x 30 mm³\u003cbr\u003e\u003cbr\u003eAdditionally required:\u003cbr\u003eU17309-230 Power Supply for U17308 (230 V, 50\/60 Hz)\u003cbr\u003eU17309-115 Power Supply for U17308 (115 V, 50\/60 Hz)","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419089248533,"sku":"3BS1003059","price":617.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U17308_01_1200_1200_Fresnel-Mirror-Experimental-Set.jpg?v=1761023977","url":"https:\/\/unitedsupplycorp.com\/products\/fresnel-mirror-experimental-set-366-00","provider":"United Supply Corp.","version":"1.0","type":"link"}
