The phase profile is written into UV fused silica by surface-relief processing and is calculated point-to-point from the incident beam, the 100 mm effective focal length and the target output geometry. The element measures 16×16 mm, installed in a Ø25.4×4 mm mechanical housing and operates at 532 nm with a 6 mm incident spot (M2\u0026lt;1.3), giving a 15×15 mm clear aperture, \u0026gt;98 % transmittance and \u0026gt;90 % diffraction efficiency (FWHM).\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLaser medical and aesthetic systems\u003c\/li\u003e\n  \u003cli\u003eLaser material processing and micromachining\u003c\/li\u003e\n  \u003cli\u003eLaser surface treatment and cleaning\u003c\/li\u003e\n  \u003cli\u003eFlat-top illumination and beam homogenization\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConstruction \u0026amp; Performance\u003c\/h3\u003e\n\u003cp\u003eUV-grade fused silica keeps absorption low and the damage threshold high, so the element tolerates the high average and peak powers typical of industrial and ultraviolet lasers. Because the surface relief is deterministic rather than scattering, the output keeps its rectangular shape with sharp edges, \u0026lt;10 % unevenness (RMS) and an edge roll-off of 6.02 μm. Alignment tolerances are ±0.3 mm (±5% of the input beam diameter) eccentricity and ±5 ° tilt.

Blow off loose particles before any contact cleaning, then use optical-grade solvent with lens tissue. Observe the orientation of the structured face when mounting, respect the specified incident spot size and beam quality, and store the element in its original container in a clean, dry environment away from direct sunlight.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":48994348925082,"sku":"DOE25Q-532-FTR6733-6-UP","price":4086.62,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/high-power-homogenizing-doe-532-rectangle-product_28b5bf80-affd-4dbc-868c-0ca9d2e066e5.jpg?v=1786413044","url":"https:\/\/waveqvanta.com\/products\/high-power-homogenizing-doe-doe25q-532-ftr6733-6-up","provider":"WaveQuanta","version":"1.0","type":"link"}
