The manufacture of precise optical prisms is time-consuming and requires appropriate manufacturing and metrological expertise. During fine grinding, an appropriate basic angular accuracy of the prism must be achieved, as the material removal during polishing is much lower than during grinding. … [Read more...] about GONIOMAT Extension for Ground Prisms – Save Time and Cost in the Production Process.
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 … [Read more...] about An Engineer’s Job Is Never Done: Why We’re Developing A High-Accuracy Angle Generator With Our SBIR Grant
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 … [Read more...] about How To Measure the Focal Power of a Lens With Dioptometers & Dynameters
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 … [Read more...] about Measuring the Geometry of Prisms, Polygons & Wedges Using the GONIOMAT M Goniometer By Möller-Wedel Optical
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. … [Read more...] about Measuring Straightness and Parallelism with the ELCOMAT® 3000 Electronic Autocollimator
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 … [Read more...] about Möller-Wedel Optical Autocollimator Use Case: Duclos Lenses Autocollimator Bench for State-of-the-art Motion Picture Lens Calibration
