We developed tilted null screens to test off-axis conic surfaces. This method offers adjustable sensitivity and screen size for precise optical testing, demonstrated on a parabolic mirror.

Area of Science:

  • Optical Engineering
  • Metrology
  • Surface Testing

Background:

  • Testing off-axis optical surfaces is crucial for advanced optical systems.
  • Traditional null tests can be complex and limited in flexibility.
  • Conic surfaces present unique challenges in optical metrology.

Purpose of the Study:

  • To introduce a novel design for tilted null screens.
  • To enable controlled testing of off-axis conic surface segments.
  • To enhance the flexibility and sensitivity of optical surface tests.

Main Methods:

  • Design and theoretical analysis of tilted null screens.
  • Investigating the effect of tilt angle on screen size and test sensitivity.
  • Experimental validation using a fast off-axis concave parabolic mirror with an elliptical aperture.

Main Results:

  • Tilted null screens offer adjustable control over test sensitivity and screen size.
  • Positive tilt angles increase sensitivity and reduce screen size in the sagittal caustic region.
  • Preliminary experimental results confirm the design's efficacy on a specific parabolic mirror configuration.

Conclusions:

  • Tilted null screens provide a versatile and effective method for testing off-axis conic surfaces.
  • The design allows for optimization of optical testing parameters.
