Axicon lens element LZAX series

conicalglassvisible

Axicon focus lenses have one conical surface and are used to produce a ring focus beam. Typically, axicon focus lenses have a second flat surface and are used in combination with a focusing lens. Our high-grade ZnSe Axicon lenses are made from a manufacturing process suited to the axicon angle and the accuracy required. For small angle, high accuracy lenses, the manufacturing process involves diamond-machining. Standard Axicon lens – Axicon cone angle equal to 180°-2α (+/-0.01 deg): α (°) Cone Angle 140°: 20° Cone Angle 160°: 10° Cone Angle 165°: 7.5° Cone Angle 170°: 5° Cone Angle 175°: 2.5° Cone Angle 179.5°: 0.25°= 15'
