Diffusion lighting element "Fresnel lens"
Output to the irradiation surface as uniform light! Solve the issue of irradiation unevenness with various combinations of elements!
The "Fly Eye Lens" is an imaging element that arranges the same single lens in both vertical and horizontal directions. By passing light output from a fiber laser through this product, it is possible to create the same conditions as a multi-point light source, enabling uniform illumination. Additionally, each lens is joined using a unique technique after being polished. Coatings with high transmittance and durability in the ultraviolet range are also available. It is mainly used in the illumination systems of semiconductor exposure equipment. 【Processing Specifications】 ■Outer Diameter: Up to 420mm ■Number of Elements: Up to 200 ■Material: BK7, Quartz Glass ■Lens Shapes: Plano-convex Lens, Biconvex Lens, Drum Lens ■Adhesion Method: Frit Adhesion, UV Adhesion *For more details, please refer to the PDF document or feel free to contact us.
