| Chart Projector |
 |
| An automatic optotype projector with halogen bulb which, tanks to its high resolution lens and top quality optotype (produced with the sophisticated DIADUR method), provides completely clear images with even the smallest optotypes and allow projection to take place undernormal lighting conditions. The octotypes are sealed in a hermetic chamber thus ensuring high definition and precise contrast that remain unaltered in time. |
The projector is controlled by an infrared remote control, according to two methods: the selection of individual tests by pressing the corresponding button or the programming of a sequence of tests. Two independent programmes can be memorised and programming is possible for all the tests.
The use of step by step motors, controlled by a microprocessor makes it possible to pass immediately from any one test to another. The high quality of the motors ensures speed and precision in the presentation of the tests without any vibration.
An automatic setting device, provided with an exposure metre on one side of the projector that reads the light reflected on the screen, and a contrast stabiliser, controlled by a microprocessor, ensures a precise calibration of the effective contrast.
