White phosphor screens are a newer type of phosphor screen and they are becoming increasingly popular. These screens are made from a phosphor material that emits a white light when it is struck by a photon of light. The white light emitted is then intensified by the image intensifier, producing an image that appears in shades of grey.
The main advantage of the white phosphor screens is that they offer the user a better level of detail. This makes it easier to distinguish between objects in the dark. The colour of the image also makes it easier to identify objects in the dark, as the shades of grey can be easier to distinguish than the shades of green.
Advantages and Disadvantages
Both green and white phosphor screens have their advantages and disadvantages. Green phosphor screens offer better contrast and depth perception, while white phosphor screens offer better detail and object identification. Ultimately, the choice of which type of phosphor screen to use depends on the user’s needs and preferences.
