The new MetaBright diffuse square light is a combination of three different
lighting methods all incorporated into one compact package. Having the
blended characteristics of a diffused front light, off-axis ring light and
edge illuminated backlight its in a category by itself. Like a diffused
front light the output is uniform and distributed equally from side to side.
Like off-axis lightings this light is designed to enhance edges and recesses
in material surfaces, but unlike its off-axis counterpart it provides a high aspect
ratio of diffusion and a tall beam shaping. Like a backlight the optical
elements are comprised of trans-illuminated light pipes.
This lights characteristics and its square form factor makes it
ideal for illuminating four-sided areas of interest as opposed to the round
form factor of the traditional off-axis ring lights.
The Diffuse Square Light is a special light and its applications are very limited. Before specifying, we highly recommend that your application be evaluated by one of the lighting specialists of METAPHASE, who may suggest something else.
