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.
Key Features:
- 50 to 100% larger field of view in comparison to standard test telescopes
- TRIOPTICS offers test telescopes with different focal lengths depending on the application
- Available with straight or 90° angled viewing position
- Optionally the test telescopes can be equipped with dual micrometers
- Optionally with reticle changer (RC)
Applications:
In combination with a telescope, the following measurements can be performed:
- Angle measurement
- Measurement of optical parameters (e.g. effective focal length, centration errors)
- Testing the infinite setting of optical systems
