The Vermont Photonics AKD is a USB powered Electronic Autocollimator with standard or customized software.
The AKD replaces a display head with a laptop or desktop computer allowing greater flexibility in data collection and analysis.


The AKD can be fitted with any of the Möller-Wedel objective tubes for desired accuracy and range.  Image analysis
algorithms allow measurement of angle, wedge error, 90º and prism error, refractive index, and more. Software can
generate reports, log data, and display go/no go status, and can be fully customized to your needs.  Please call for
