They redistribute the optical power of a Ø0.8 mm (1\/e²) Gaussian collimated beam at 633 nm into a uniform line profile. Within the central 80% of the generated laser line, the non-uniformity is less than 30%.\n    Compared to cylindrical lenses, Powell lenses eliminate the central hot spot and fading edges typical of Gaussian beam profiles, resulting in a more uniform line intensity.\n    LBTEK offers Powell lenses with multiple fan angles and supports customization based on specific laser module requirements to achieve optimal line uniformity.

It can be mounted to a rotation adjustment frame via the TAD-09 adapter to adjust the direction of the outgoing laser line. When used with a He-Ne laser HNL-2-RP, the 400 nm-1100 nm circular Powell prism achieves optimal laser line uniformity. Using other wavelengths or beam diameters may result in suboptimal performance.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47518232215706,"sku":"PWPD9-45-AB","price":242.84,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/1-1_E9_B2_8D_E5_A8_81_E5_B0_94_E6_A3_B1_E9_95_9C_EF_BC_8C400_20nm-1100_20nm-Ft2fxvhFeQQVc6t9mBCDYeTW46cU_1732f9eb-14d1-4e56-b5d3-87cd217b27ba.jpg?v=1772678208","url":"https:\/\/waveqvanta.com\/products\/powell-lenses-pwpd9-45-ab","provider":"WaveQuanta","version":"1.0","type":"link"}
