The CP-500 serves optometry practices and ophthalmology clinics that test distance vision in a refraction lane. A white LED projects bright, even charts at 2 to 7 m, and adjustable brightness lets the examiner match the projection to the room, from a darkened lane to a brighter consulting room.
The chart library covers the routine tests. Landolt, Snellen, Letter and Children charts support acuity testing, while Stereo, Coincidence (H/V) and Schober charts support balance and binocular vision work. Horizontal line, vertical line, and single-letter masks isolate parts of a chart so that the examiner can direct the patient to one line or one letter at a time.
Two user programs speed up the routine. Each stores up to 50 charts or masks, and the remote controller recalls them with a program switch and Next and Back buttons. A chart or mask changes in 0.3 seconds, and the rotating chart disk runs quietly, keeping the consultation calm. The examiner can move from one test to the next without breaking the patient's concentration, and the routine stays consistent from the first appointment of the day to the last.
The CP-500 integrates fully with the Rexxam DR-900 digital refractor, so the chart and refractor work together. Linear polarisation supports polarised tests, a ±10-degree tilt aligns the image, and an automatic power-off after 5 minutes switches the unit off when idle. Practices that want a bright, programmable, well-integrated chart projector will find the CP-500 a steady part of the refraction lane, with the included projection screen, dust cover, remote controller, and spare fuse ready for use.
