Compared with liquid crystal polymers, UV Fused Silica (UVFS) features low absorption and a high damage threshold. Thanks to the freely designable inner and outer diameters of the ring and the high uniformity of energy distribution on the ring, this element operates at 1080 nm with a 8.8 μm inner \/ 130 μm outer ring-shaped light spot at the standard 650mm focal length.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUVFS material, more suitable for high-power laser applications\u003c\/li\u003e\n  \u003cli\u003eCan be used to generate annular beams\u003c\/li\u003e\n  \u003cli\u003eDesign Wavelength 1080 nm\u003c\/li\u003e\n  \u003cli\u003eInner and outer diameters can be customized freely\u003c\/li\u003e\n  \u003cli\u003ewavelength range: 1080 nm\u003c\/li\u003e\n  \u003cli\u003eGaussian-to-annular energy conversion\u003c\/li\u003e\n  \u003cli\u003ePure UV Fused Silica (UVFS), High damage threshold\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThe High Power Ring-Shaping DOE has significant application potential in \u003cstrong\u003e3D printing\u003c\/strong\u003e, \u003cstrong\u003elaser welding\u003c\/strong\u003e, and \u003cstrong\u003elaser drilling\u003c\/strong\u003e scenarios.

It shapes the incident TEM00 Gaussian beam into an annular spot. The product is supplied without mechanical housings and can be used with optional compatible mechanical housings; the Ø25.4 mm×0.5 mm optical component size is compatible with standard 1-inch optical component mounting frames. Standard specifications are based on a focal length of 650mm — in actual use it can be adapted to focusing lenses with different focal lengths, and the annular spot size scales linearly with the focal length. This model delivers \u0026gt;90% diffraction efficiency and \u0026gt;98% transmittance at the center wavelength, with \u0026lt;10% non-uniformity on the ring.
