The Polaris Digital Exposure Meter is a compact flash and ambient light meter that has many features of the more expensive flash meters. A unique multi-flash feature makes it simple to calculate how many times the flash must be fired to achieve a desired f-stop. The Polaris's large LCD display shows both the shutter speed and f-stop in 1/10 stop increments.
The Polaris Flat Diffuser is used to measure the lighting ratio between main and auxilliary lights, to determine luminance values and to take exposure readings of flat subjects such as paintings or copying documents.
