Brightness comparison between VL-CB-CL and VL-CB.
Even though the luminance (lux) of VL-CB type is higher than VL-CB-CL, actual image brightness of VL-CB-CL is much brighter than VL-CB as shown in the image. (left side image is CB-CL, right side is VL-CB.)
Sharpness
Better parallelism light provides better image for measurement application. At the edge of the object, there is some reflection in case of standard back light. However, VL-CB-CL image has better contrast at the same point due to the parallelism difference.
