The CP-690 is a leading automated chart projector that could have a better thought-out remote control and better contrast.

Overview

NIDEK’s previous generation, the CP-690 automated acuity projector does pretty much everything the brand new CP-770 does, however without the compact design, the LED illumination and the crazy-good line isolation features. We do however find it to be a competent projector, coming with 33 different charts standard, decent isolation/masking options, and duochrome capability (red/green over any chart). Its biggest drawback starts with mediocre contrast when compared with modern projectors and LCD screens. Doctors alike should still have no problem refracting with the light on or off, however, depending on room size and your set-up, it may be best to lower ambient light. The CP-690’s wireless remote is well thought out, however is rather large, and may be difficult to keep in the hand throughout the refraction.
