This shows relative R/G/B throughput comparing right eye to left eye for the top of the line Mark V versus the affordable Maxbright binoviewers.

The Mark V has noticably superb balance in both overall throughput and color balance.

The Maxbright shows a dimmer image in one eye (as all three R/G/B curves are shifted left), as well as color balance differences (seen in the altered positions of the RGB curves relative to each other and the altered magnitude of the curves.)
