The Battery Pack will
provide complete portability for your PR-640, PR-650, PR-705 or
PR-880. It is a lead acid battery with charging circuitry in a rugged
enclosure with a carrying handle.
Photo Research Camera Kit provides an easy method for remotely
monitoring the field of view of your Photo Research photometer or
spectroradiometer. The adapter component of the system easily marries
the "lipstick" CCD camera to the instrument eyepiece.
