Collimating a white light beam

Click For Summary
SUMMARY

The discussion focuses on the need to collimate a white light beam from a Xenon (Xe) arc source coupled to a monochromator. The user requires a circular collimated light beam with a diameter of 1-2 mm, currently utilizing a 1.2 mm rectangular slit in the monochromator. A suggested solution involves using a large multi-mode optical fiber to collimate the output from the monochromator, although this method may result in significant light loss.

PREREQUISITES
  • Understanding of optical fiber technology
  • Familiarity with monochromator operation
  • Knowledge of collimation techniques
  • Basic principles of light sources, specifically Xenon arc sources
NEXT STEPS
  • Research optical fiber collimation techniques
  • Explore different types of monochromators and their configurations
  • Investigate methods to minimize light loss in optical systems
  • Learn about the properties and applications of Xenon arc light sources
USEFUL FOR

Optical engineers, physicists, and researchers working with light sources and monochromators, particularly those involved in applications requiring precise light collimation.

Dear all
I need collimating light from a Xe arc source.
More in details, the white light source is coupled to a monochromator. In fact I need a circular collimate light beam from the monochromator with a diameter of 1-2 mm.
At the moment I am using a (rectangular) slit in the monochromator of 1.2 mm.
Can you suggest me a possible solution?
Thank you

You are trying to collimate the monochromator output? That can be tricky. One possible solution is to launch the output into an optical fiber- a large multi-mode one should be fine- and collimate the fiber output. It's going to be very lossy, tho.

What is your application?
