When measuring uniformity, in order to minimize cosine falloff in imaging systems with wider field of view lenses, it is important to have a light source that produces uniform illumination across the entire field of view.  The equipment listed below can be deployed to produce uniform images that fit the spectral requirements and field of view of your imaging system:

Field of View

Visual and/or Narrow Band 

Broad Spectrum VIS+IR / SWIR

<= (80°, ~110°)

Imatest Lightbox

Gamma Scientific RS-7-1 (80°)

<= 180°

 

Gamma Scientific RS-7-6 (180°)

<= 300°

Colorspace LB2
