UV-to-NIR Corrected Triplet Lenses


  • Calcium Fluoride and UV Fused Silica Elements
  • Broadband Color-Corrected Design from 193nm to 1000nm
  • Ideal for Fluorescence and Spectroscopy Applications

Designed with broadband applications in mind, our UV-to-NIR corrected lenses provide a consistent focal length (see chromatic shift information below) for wavelengths ranging from 193nm to 1000nm. Manufactured with premier grades of Calcium Fluoride and Fused Silica, these infinite-conjugate triplets are perfect for imaging applications utilizing a wide spectrum of wavelengths. Typical uses include fluorescence research in which the emitted light is in the visible and near infrared regions of the spectrum or in dual-pass systems in which the same lens is used to illuminate the excitation material as well as collect the emissions from it. Elements are uncoated and mounted in a 30mm diameter aluminum housing. Antireflection coatings available, however a minimum order quantity will apply.

Full prescription information available.
