Overview

Customized Znse conical Axicon lenses for infrared and CO2 laser applications

PRODUCT DESCRIPTION
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
Features
* · Transform a Collimated Beam into a Ring
* · Five Physical Angles Available: 0.1°, 0.2°, 0.5°, 1.0°, and 2.0°
* · Broadband AR Coating with Ravg <1% from 7 to 12 µm

Application
for mid-infrared laser applications and for use with CO2 laser applications, like materials processing
