OPTICAL TESTING INSTRUMENTS

Tools for Optical Workshops

 

Vermont Photonics offers the  Möller-Wedel line of specialized instruments used for a variety of measuring and testing applications in optical component production environments.

Tools such as dioptometers and dynameters are used in the calibration and measurement of magnification and optical power of lenses and eyepieces found in instruments such as telescopes, binoculars, cameras, microscopes and other similar items.

Dioptometers (Diopter Telescopes)

 

Dioptometers (diopter telescopes) are adjustable focus telescopes that measure the optical power of lenses in diopters. The measuring result can be directly read from the diopter graduation.

Dioptometers are most often used to calibrate or measure the diopter adjustment of eyepieces found on telescopes, binoculars, cameras, microscopes, and endoscopes. Dioptometers can be adapted to other applications as well, and can even be used as a short focal length collimator by replacing the eyepiece with illumination. Dioptometers are available with different measurement ranges and magnifications.

Application Examples:

 

  • Fast testing of optical power

  • Testing the diopter graduation and infinity adjustment of eyepieces

  • For additional enlargement on telescopes, o.g. when adjusting reticles

  • As reading telescopes in the negative distance range

Ordering Note:

 

  • The diopter telescope is equipped with an eyepiece f=14.7 mm but can be equipped with eyepieces f=25 mm or f=10 mm on request.

Double Adjustment Telescope

 

The double adjustment telesope is an instrument for testing and adjustment of binoculars for:

  • Parallelism of optical axes

  • Image erection

  • A stabile reliable pecision instrument in connection with a distant target (< 3 km)

  • It is easy to handle and therefore the right instrument for use in laboratory, production control and repair workshop.
