Sub-aperture stitching interferometer expands optical fabrication and testing services by increasing interferometric capabilities, providing radius of curvature and surface figure measurements
Janos Technology, a supplier of advanced optical assemblies and precision infrared (IR) optics, announces the addition of the QED sub-aperture stitching interferometer (SSI).
The SSI will greatly expand Janos's current range of optical fabrication and testing services by increasing interferometric capabilities, providing radius of curvature and surface figure measurements for both high numerical aperture (NA) and large aperture optics.
The automated SSI work station features a five-axis CNC machine base integrated with a Zygo VeriFire AT phase-shifting interferometer capable of measuring lenses up to 280mm diameter and (NA) of 1.
The SSI automatically acquires and stitches sub-aperture data, calculates and compensates for reference wave-front errors thus achieving better than lambda/100 P-V accuracies (@632.8nm).
Erik Stover, director of research and development for Janos Technology, notes: "The new sub-aperture stitching interferometer will enhance the precision metrology that is available from Janos Technology.
"We're pleased to offer this extraordinary capability to our customers who require precision metrology of high NA and large aperture optical components".
Janos Technology offers custom precision optics, optical assemblies, and a family of thermal imaging lenses, ideal for multi-spectral applications in military and defense, industrial, commercial OEM, R and D, aerospace and astronomy.
The company's online store also features a large selection of off-the-shelf optical components.
