How can we help?
For red-green visual impairment:
The advantage of ONYX and BW Picture tubes with their "black/white“ Image representation consists in the fact that people with red-green visual impairment can perceive the image better than with a green (P22) or green-yellow (P43) tube with the same performance parameters. This is not an advantage for people with normal vision, but the image is often perceived as more natural and is therefore becoming increasingly popular with "normal-sighted people".
Of course, all devices offered as new have brand new picture tubes installed. They are also protected against lightning and shock. A data sheet with the original measured values from Photonis is supplied with each device.
