Visual Autocollimators

Visual autocollimators measure the angle of optically flat (1/4 wave or better), reflective surfaces in arc seconds by viewing a graduated reticle through an eyepiece.

The longer the focal length of the visual autocollimator, the greater the angular resolution and the smaller the field of view. These autocollimators are fixed-focus at infinity, however we have Möller-Wedel adjustable focus autocollimators available as well. Eyepieces can be replaced by analog or digital cameras with for monitor screen viewing or software image analysis. Various adapting lenses provide different magnifications for use with cameras. A complete line of autocollimator mounts, mirrors, pentaprisms, and achromats are available for specific applications.

I want to thank you and your team for doing an incredible job from the start… I, literally, could not have been more pleased both with your professionalism, technical expertise, and patience/support during these various contractual events.

-Lead ASTS Electro-Optical Systems Engineer, Boeing

Vermont Photonics is the first company that the audit team has ever seen to have a policy for the components considered in uncertainty calculations.

Noteworthy Practice from Quality Audit Report, Los Alamos National Laboratory

Dealing with suppliers such as you certainly makes my job easier. The equipment purchased enabled us to further our relationship with our customer, who is a very well-known and highly respected global automotive OEM.

-Automated lens alignment equipment manufacturer

Customer focus is really appreciated, and unfortunately too rare. I loved dealing with your company… The collimator worked flawlessly out-of-box, as compared to the previous one from another company that I never could get comfortable with in 18 years!

-Civilian contractor for the US military

I returned the demo equipment today, sadly. It is a really quality instrument and worked beyond my expectations. Thanks for being so easy to work with on this. I really appreciate it.

-Roylnn Serati, Boulder Nonlinear Systems

It is a pleasure to deal with suppliers that take ownership and deliver a great product.

-Global eye care device manufacturer

The modifications were very nicely done and we are now able to measure to the center of an eight inch plate, which we’ve long wanted to do. The new software and user interface is great. It’s very easy to learn and operate and our work gets done much faster than before.

-Optical filter manufacturer

My recent experience with Vermont Photonics and Möller-Wedel products has been nothing short of exceptional.

-Designer of firearms and rescue illumination systems

I was VERY happy with the communication and general ‘on the ball’ status of your company… Cal service turnaround was something like a week, stupendous by any standard.

-Major interferometer manufacturer

Service from you and your office has always been excellent – especially the quick responses to any requests or questions.
