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.

Cost effectivity

The modular design allows highest cost effectiveness due to identical basic components in each configuration.

Flexibility

Unlimited flexibility in test setups with basic components to cover current and future applications. The basic components are interchangeable and compatible with each other.

Diversity

TRIOPTICS offers autocollimators, collimators and telescopes with different focal lengths and objective tube diameters. In addition, there is a large selection of reticles, which can also be custom-made if required.

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

Request OptiTest® Autocollimators

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

Focusable Collimator

Collimators with variable focus setting

The reticle nozzle of the focusable 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

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)

Focusable 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 focusable 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)

There are reticles for collimators and reticles for telescopes (Eyepiece-Reticle). For both types you have to distinguish between reticles for standard field of view and large field of view corresponding to the instrument you have chosen.

For telescopes: Telescopes are used to observe objects that are imaged onto the eyepiece-reticle. For this reason it is recommended to use a positive eyepiece reticle.
For collimators: Collimators image the structure imprinted on the reticle at some distance. Generally every reticle can be selected, but if fine structures are imaged it is recommended to use a negative reticle.
For autocollimators: For autocollimators the right combination of reticles is important. RET-32 / RET-12 means RET-12 is the collimator-reticle and RET-32 is the eyepiece-reticle.

Upgrades & Accessories

In addition to the OptiTest^® collimators, telescopes and autocollimators, TRIOPTICS offers a large range of opto-mechanical accessories, often required for certain standard applications.
