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.

Key Features

  • The focal point setting is variable and both a finite and infinite distance setting are possible
  • 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 for measuring image angles in two different directions.
  • Optionally with reticle changer (RC)
