Edmund Optics® (EO), the premier provider of optical components, announces a new line of Laser Grade Aspheric Lenses with a λ/40 RMS aspheric surface tolerance, making them ideal for high precision laser focusing applications.
TECHSPEC® λ/40 Laser Grade Aspheric Lenses feature ultra-precision and aberration-free aspheric surfaces with a surface tolerance of λ/40 RMS. They are precision polished using magnetorheological finishing (MRF), a process which selectively removes material in a highly repeatable and controlled manner. The polishing method used for these aspheric lenses enables diffraction-limited performance and a guaranteed exceptional Strehl ratio > 0,8 at their Nd:YAG design wavelengths.
TECHSPEC λ/40 Laser Grade Aspheric Lenses maximize throughput with high-performance Laser Line V-Coatings for < 0,25% reflection at their design wavelengths. These laser grade aspheres feature fused silica substrates and are available in standard imperial sizes with f/2 designs.
