The Flat Box Field Generators from Artesky provide a fully-illuminated, color-neutral, pure white LED field for the highest quality flat field calibrations. These also work extremely well with color cameras. 

The image is absolutely flicker-free, meaning very short exposure times are possible with this. One major advantage this product has over other, commonly-used flat field boxes is the precise dimmer located on the backside of the box. This 10:1 dimmer allows for exact brightness adjustment.
