A modified two-lens system (TLS) improves laser collimation testing for optical experiments. This new setup is more compact and yields better results than conventional methods.

Area of Science:

  • Optics and Photonics
  • Experimental Physics

Background:

  • Laser collimation is critical for various optical systems.
  • Existing two-lens systems (TLS) are used for collimation testing.
  • A need exists for more compact and efficient collimation testing devices.

Purpose of the Study:

  • To propose a modified two-lens system (TLS) for laser collimation testing.
  • To enhance the performance and reduce the size of conventional collimation testing setups.
  • To validate the proposed method through theoretical modeling and experimental results.

Main Methods:

  • A modified two-lens system (TLS) approach was developed.
  • The second TLS component was repositioned between two gratings.
  • Theoretical modeling, simulations, and experimental validation were performed.
