Providing a small and adjustable light source via a fibre optic cable, terminating in a ceramic ferule illuminated by a super-efficient and high intensity LED, the Picostar Plus can provide an equivalent magnitude sweep of 8 magnitudes in brightness. This light source is varied and controlled by the top-mounted graduated control knob. Suggested testing distances for differing apertures of instruments are printed on the top of the Picostar for handy reference. These measurements are based on the Rayleigh test criterion, which provides a very accurate strict test for optics. Those who are unable to adhere to these recommendations, due to limits on space, will happily still be able to use the Picostar to adequately test their instruments, however.
Powered by a standard and commonly available single PP3 9V cell, the Revelation Picostar Plus will provide 16 hours of illumination at greatest brightness per battery.
