Collimated light source for characterizing stray light (flare)

The Imatest Stray Light LED Source (V2) is specifically designed for characterization and testing of stray light (flare) in cameras. It projects an image of a small point-like source as a uniform, collimated beam of light. When imaged by a camera, the saturated image of the source produces stray light that can be visually inspected or analyzed using Imatest stray light analysis software

This hardware is compatible with the Imatest Benchtop Test Stand.

Description

Imatest Stray Light LED Source Features

  • Small source angular size for high resolution stray light measurements and detailed characterization of stray light, including diffraction spikes, ghosting, and veiling glare
  • Spatially uniform collimated beam benefits repeatability of measurements
  • Designed for low internal reflections (e.g., no halo) by intentionally underfilling the collimating lens with light
  • Adjustable intensity/brightness
  • Adjustable lens focus, allowing for both collimated or diverging beams
  • Includes programmable power supply for powering LED; TEC and fan powered by AC adapters

Notable Improvements Over Previous Generation

We’ve redesigned out Stray Light LED Source to bring significant improvements in technical performance and capability:

  • Smaller source size reveals higher frequency stray light artifacts, providing higher resolution images of stray light in the camera
  • Improved collimation and significantly improved spatial uniformity of the output beam, providing better test repeatability and control
  • Introduced brighter white LED and new options for NIR LEDs (850nm and 940nm)

Specifications Details
Angular Diameter The projected point image has an angular diameter of 0.11°
Beam Diameter The uniform area of the beam has a diameter of 20-25 mm within 1 meter when collimated, with the ability to achieve larger beam diameter by adjusting the lens focus to output a diverging beam. At max divergence, the uniform area has a diameter of 50 mm at 1 meter away.  
Beam Divergence Adjustable collimation/focus with theoretical minimum half divergence angle of 0.055°
