Avoiding Multi-Shadows

Multi-shadowing is directly related to the selection and layout of LEDs on a board, plus how the emitted light is diffused as part of the total light engine design.  In the image below you can see how the Dazor Stretchview magnifier uses 80 wide-angled LEDs densely populated on one board while competing magnifiers use significantly fewer LEDs spaced much further apart.

Avoiding Multi-Shadows

The Result

The lack of LEDs and poor design of most competing magnifiers leads to this multi-shadowing effect.  This is a big problem when light is used for close proximity inspection viewing as the multi-shadowing is a major viewing distraction.  It can potentially cause defects to be overlooked, reduce productivity and even cause eye fatigue.
