Thermal Imaging

Introduction

As part of our manufacturing process for polished and coated finished optics we are able to offer generated blanks with tight tolerances for thermal imaging applications. The majority of our lenses, for all applications, are made from ZnSe and ZnS. They are manufactured to the highest industry standards, backed up by the most modern metrology available.  Diameters in the range of 15mm to 150mm are within our capabilities.

ZnSe Generated Blanks

ZnSe is the preferred material for a broad range of optics due to its visible transmission and its low absorption at infrared wavelengths.  In high-power applications, it’s essential to carefully control the internal defect structure and the bulk absorption, as well as employing minimum-damage polishing and the highest quality coatings.  ULO Optics verify material absorption using CO2 laser calorimetry in atmospheric environments on each and every component, and can provide testing certification upon request.
