This objective lens is designed for the Mirau style of white light interferometers and maintains a high level of temperature tolerance. The optimized NA of 0.8 provides improved light gathering, with a working distance of 0.7 mm.
White Light Interferometry Objective lens WLI100XMRTC
Objective lens designed specifically for integration with white light interferometers.
Each lens can be adjusted to compensate for thermal drift using the built in correction ring.
