OptiTest®
Visual optical measurement instruments
The optical testing usually requires a wide range of configurations specific to the application or the parameters to be measured.
The large variety of the set-ups is, however, a combination of basic optical instruments known as collimator, industrial telescope, diopter telescope, dynameter, autocollimator as well as mechanical hardware for positioning of the basic optical instruments. Reticle and filter changers are optionally available.
To cover all conceivable testing set-ups required by fast changing applications, the components of OptiTest® line are designed as a modular system.
Autocollimators
The Autocollimator is a single instrument combining the functions of a collimator and a telescope. It detects small angular displacements of a mirror by means of its own collimated light. TRIOPTICS offers autocollimators with different focal lengths depending on the application. You can choose between a fixed focus setting with infinite setting and a variable focus setting with finite distance setting. Both versions are available with straight or 90° view.
Autocollimator
Autocollimators with fixed focus setting
The two reticles of an autocollimator with fixed focus setting are positioned in the focal plane of the corrected objective lens, so that the emerging beam is parallel. This usual configuration is known as infinity setting, i.e the autocollimators are focused at infinity.
- Fixed focus setting with infinite setting
- Dual micrometer screw for shifting the reticle (optionally with digital display) available
Focusing Autocollimator
Autocollimators with variable focus setting
The reticles of a focusing Autocollimator (focusing Autocollimation telescope) can be moved out of the focal plane of the objective lens so that the autocollimator can be focused at finite distances.
- Variable focus adjustment with finite distance setting
- Dual micrometer screw for shifting the reticle (optionally with digital display) available
Large Field Autocollimator
Large Field Autocollimators with fixed focus setting
To meet customer requirements for testing optical instruments with large field of view, TRIOPTICS developed a unique line of autocollimators.
- 50 to 100% larger field of view in comparison to standard autocollimators
- Fixed focus setting with infinite setting
- Dual micrometer screw for shifting the reticle (optionally with digital display) available
Focusable Large Field Autocollimator
Large Field Autocollimators with variable focus setting
The reticles of a focusing autocollimator can be moved out of the focal plane of the objective lens so that the autocollimator can be focused at finite distances.
- 50 to 100% larger field of view in comparison to standard autocollimators
- Variable focus adjustment with finite distance setting
- Dual micrometer screw for shifting the reticle (optionally with digital display) available
Collimators
TRIOPTICS offers different collimators depending on the measurement task. As a standard the collimators are set up in infinity setting meaning that they project the image of a reticle to infinity. TRIOPTICS offers collimators with different focal lengths depending on the application. You can choose between a fixed and a variable focus setting. Both versions are also available with a very large field of view.
Collimator
Collimators with fixed focus setting
The Collimator is an optical instrument consisting of a well corrected objective lens with an illuminated reticle at its focal plane.
The emerging beam is parallel (collimated beam), so that the image of the reticle is projected at infinity.
- The image of the reticle is projected into infinity at a wavelength of 546 nm (other wavelengths also available on request)
- The distance between reticle and objective lens is fixed
- Dual micrometer screw for shifting the reticle (optionally with digital display) available
Focusing Collimator
Collimators with variable focus setting
The reticle nozzle of the focusing collimator (finite distance setting) is mounted on an extendable tube to allow the focal point to be adjusted. This makes it possible to achieve finite and infinite distance settings.
- The focal point setting is variable and both a finite and infinite distance setting are possible
- Dual micrometer screw for shifting the reticle (optionally with digital display) available
Large Field Collimator
Large field collimators with fixed focus setting
To meet customer requirements for testing optical instruments with large field of view, TRIOPTICS developed a unique line of collimators providing a significant increase of field of view.
- 50 to 100% larger field of view in comparison to standardCollimators
- The image of the reticle is projected to infinity
- Dual micrometer screw for shifting the reticle (optionally with digital display) available
Focusing Large Field Collimator
Large field collimators with variable focus setting
The focal point setting is variable and both a finite and infinite distance setting is possible.
- 50 to 100% larger field of view in comparison to standard collimators
- Dual micrometer screw for shifting the reticle (optionally with digital display) available
Telescopes
TRIOPTICS offers different telescopes depending on the measurement task. As a standard the Industrial Telescopes are set up in infinity setting meaning that they image an object at a far distance into the image plane of the objective lens. TRIOPTICS offers industrial telescopes with different focal lengths depending on the application. They are available for straight or 90° angled viewing
Telescope
Industrial Telescope with fixed focus setting
The Industrial Telescope is preset to infinity and images an object at a far distance into the image plane of the objective lens. The image is then magnified and visually inspected by an eyepiece. For measurement purposes usually a graduated reticle is located in the image plane. The magnification of the Industrial Telescope is given by the ratio of the objective focal length and the eyepiece focal length.
- The image is at an infinite or very large distance
- Optionally the industrial telescopes can be equipped with dual micrometers
- Optionally with reticle changer (RC)
Focusing Telescope
Telescope with variable focus setting
Attaching a draw out tube to the reticle adapter to move the reticle out of the focal of the objective lens, the standard telescope becomes a focusing telescope. Depending on the location of the reticle relatively to the focal plane, it results a real or a virtual image at a finite distance.
- The focal point setting is variable and both a finite and infinite distance setting are possible
- Optionally the test telescopes can be equipped with dual micrometers for measuring image angles in two different directions.
- Optionally with reticle changer (RC)
Large Field Telescope
Large field Telescope with fixed focus setting
To meet the demands that customers are placing on the testing of optical instruments with a large field of view, TRIOPTICS has developed a new and unique range of test telescopes that are characterized by a significantly larger field of view.
- 50 to 100% larger field of view in comparison to standard test telescopes
- Optionally the test telescopes can be equipped with dual micrometers
- Optionally with reticle changer (RC)
Dynameter
Dynameter
Measurement of magnification of telescopes
The Dynameter is used in optical testing for:
- Measuring of the diameter of exit pupil
- Checking the distance between eyepiece and exit pupil
- Measurement of magnification of telescopes
Diopter Telescopes
Diopter Telescope
Focusing telescope
The Diopter telescope or dioptometer is a focusing telescope measuring the power of lenses in diopters. The results of the measurement can be read off on a graduated scale.
- Dioptometer can be attached to customer individual holders
- Nearly all TRIOPTICS Dioptometers have large graduations and permit easy readin
- Eyepieces are interchangeable and can be adapted to custom needs
