To measure straightness of a beam with the use of Auto-Collimator. – To identify the principle of Auto-Collimator device. – To be able to draw conclusions about. Auto-collimator is an optical instrument used for measuring small angular differences. Relevant for: Autocollimator The autocollimator combines both optical tools, the collimator and the telescope into Operating principle of the autocollimator.

Typically, people can resolve from 3 to 5 arc-seconds. Optical autocollimatir Optical metrology Measuring instruments. The autocollimator is than adjusted to coincide with the laser direction by using its built in mechanical adjustment.

The magnification of the telescope is given by the ratio of the objective focal length and the eyepiece focal length. Illuminating Products CES In an electronic autocollimator the eyepiece is replaced by an electronic camera with discrete sensor pixels e.

In combination with a telescope, the collimator can also be used for aligning machine elements along the line of sight. Applications News Features Enlightening Applications. Attaching a draw out tube to the reticle adapter to move autocollimattor reticle out of the focal of the objective lens, the standard telescope becomes a focusing telescope.

Autoco,limator operating principle is explained in the following. The bore sighting procedure is performed in two stages. This set up in is known as infinity setting.


In a second application the basic requirement is to bring the laser and its sight to be aligned with a mechanical mounting interface. Due to the collimated beam infinity adjustment the measurement results are independent from the distance to the object under test. Latest from the trade show floor. The shift of the autocollimation image from the center of reticule in both x and y directions is proportional to autocollimztor mirror’s t ilt angle. They prlnciple typically used to align components and measure deflections in optical or mechanical systems.

Optical Angle Measurement – TRIOPTICS

First step, aligning of Autocollimator to the laser using the periscope. Modern technologies are characterized by extreme complexity, and by the fact autocollimztor one system is built by fusing several technologies together. This page was last edited on 12 Octoberat The development and implementation of state-of-the-art measuring instrumentation that combine laser analyzing and traditional optics allow for a significant advancement in the area princiole target-less bore-sighting and accurate alignment.

Micro-Radian autocollimators are available in both analog or digital “servo” versions suitable for providing high speed, real-time angular monitoring in OEM servo-feedback and servo-feedforward systems.

Optical Angle Measurement

The operator views the reflected pinhole image s through an eyepiece. Please contact us to discuss your particular application. New approaches to alignment and lasers combined with diamond machining of intricate optical assemblies will lead to proper assembly of mechanics, lasers and optics. Visual Autocollimators Digital Autocollimators Digital autocollimators use an electronic photodetector to detect the reflected beam. Critical Link, a provider of embedded electronics solutions, This point is also located at a finite distance.

In some distance, the collimated beam is reflected back from a mirrored surface.


A small angular offset between the two can also can be easily achieved. Angle comparisons by aperture sharing.

Visual autocollimators can also be equipped with an eyepiece reticle for aid in lining up test optics to a master reference. Written by Oren Aharon 21 July Micro-Radian is the only company that manufactures autocollimators with laser light sources.

Micro-Radian Autocollimator Principles of Operation

The autocollimator projects a beam of collimated light. Focusing Collimator Aktocollimator distance setting Virtual image. Click here for a selection of Micro-Radian bench top digital autocollimators or click here to view the PC-based digital autocollimators. The autocollimator is a very sensitive angle measuring device and is thus used for the precise angular adjustment of optical or machine components.

The collimator is often used as a test chart projector for the inspection of infinity corrected objective lenses, e. The autocollimation effect and name is derived from the fact that the same telescopic lens is used to project the image and collect its back reflection from a mirror element. The alignment effect is achieved by a specially designed instrument called the Alingmeter.

This procedure will bring the sight to be perfectly aligned to the laser direction. The new RSL safety laser scanner with detailed measurement value
