Collection of light

The collection of light is the first step in making a quantitative optical measurement.

Here are some ways to collect light:

• Apertures
  • Simple aperture to collect collimated laser beam
  • Simple aperture to collect restricted solid angle of light
  • Aperture of an integrating sphere
  
  
• Optical fiber
  
  
• Isotropic collector
