Description
The telescope is an optical tool that images an object at a far distance – usually preset to infinity – 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 telescope is given by the ratio of the objective focal length and the eyepiece focal length.
When the incoming beam is parallel, the image observed through the telescope is located at infinity i.e at a long distance. This set up in is known as infinity setting.
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
Industrial Telescope:
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.
Focusable Test Telescopes:
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.
Large Field Telescopes:
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.
