The LBTEK Polymer Annular Shaping DOE is fabricated using UVFS substrates and Liquid Crystal Polymer (LCP) materials, featuring a sandwich structure that converts incident TEM00 Gaussian beams into intensity distributions with central holes.
The Polymer Annular Shaping DOE is specially optimized for industrial applications with enhanced material durability. It offers high efficiency, stability, ease of operation, and a high damage threshold, with excellent temperature stability and a wide range of incident angles.
Key Features
- Liquid Crystal Polymer/UVFS Window Sheet substrate, sandwich flat structure
- Applicable for generating annular (ring-shaped) beams
- Highly efficient and stable, easy to operate, large incident angle, high damage threshold
- Design wavelength: 532 nm, 1064 nm; annular order m: 1, 2, 4 available
- Flexible customization of parameter specifications available
m=4 Series
The LBTEK m=4 Polymer Annular Shaping DOE is suitable for incident light with diameters ranging from Ø1.0 mm to Ø21.5 mm, with a conversion efficiency of ≥99.5%. The DOE converts TEM00 Gaussian beams into annular intensity distributions with a central hole corresponding to topological order m=4.
