An Engineer’s Job Is Never Done: Why We’re Developing A High-Accuracy Angle Generator With Our SBIR Grant

Accuracy is everything in the metrology world, and Vermont Photonics already supplies the highest accuracy measurement instruments in the United States. Could that bar be raised even higher? A Small Business Innovation Research (SBIR) Phase I grant from the National Institute of Standards and Technology (NIST) is making it possible to find out just how accurate we can go […]

How To Measure the Focal Power of a Lens With Dioptometers & Dynameters

When it comes to matters of the eye, accurate focus and magnification are the name of the game. Luckily, Vermont Photonics has devices known as dioptometers and dynameters, which can be used to measure and calibrate the focal power of a lens and measure the range of both focus and magnification. If you use an instrument or optic with […]

Measuring the Geometry of Prisms, Polygons & Wedges Using the GONIOMAT M Goniometer By Möller-Wedel Optical

When it comes to measuring geometry of your prisms, polygons, wedges, and other parts, precision and accuracy are key. Originally a tool used for surveying, goniometers used for metrology have taken significant steps in recent years. The introduction of the GONIOMAT line of automatic goniometers marks a new era allowing for the precise measurement of prisms. In this video, […]

Measuring Straightness and Parallelism with the ELCOMAT 3000 Electronic Autocollimator

When a fraction of an inch is the difference between a precision machine and scrap metal, you don’t want to take chances when it comes to straightness and parallelism measurements. Luckily, Vermont Photonics has an electronic autocollimator that can measure straightness easily and accurately. Measure straightness and parallelism better with the help of the ELCOMAT 3000 Electronic Autocollimator from Möller-Wedel Optical.

First […]

Möller-Wedel Optical Autocollimator Use Case: Duclos Lenses Autocollimator Bench for State-of-the-art Motion Picture Lens Calibration

The Problem: Ensuring Lens Performance
In the motion picture business, an assistant camera operator must be absolutely confident that the focal length markings on each lens are accurate; that the chosen lens for a shot will produce a perfect, predictable image by 21st-century standards. Because he/she is unable to access the primary operator’s visual reference monitor during a shoot, a […]

Small Angles and Autocollimators

Precision angle measurement is a critical component in the construction of many modern electro-optical assemblies. Laser-based interferometers and autocollimators are among the most common optical tools for non-contact angle measurement. All of these systems direct an optical signal at a reflective surface and derive angle information either from interference effects of the reflected signal with a reference signal or […]
