Achromatic Triplet Lenses

Posted by Ningliu on May 4th, 2017

A triplet lens is a compound lens consisting of three single lenses. The triplet design is the simplest to give the required number of degrees of freedom to allow the lens designer to overcome all Seidel aberrations.

• 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.

For extremely precision sensitive system requirement, please contact us for further information of optical materials, our engineers are more than happy to evaluate your design and have our experiences of manufacturing input help to define the most appropriate tolerances.
