Please be advised that for very best results, mirrors should be used in conjunction with standard optical projection units.
With this traditional design of optical system, the projected image is reflected by the front surface mirror and only acheives a sharp focus on the viewing screen. Any minor marks, dust, etc. which might in time have been collected by the mirror in use, have little if any effect on the final image. This is because the rays of light at the surface of the mirror, the reflecting point, are 'incoherent'. In other words, no particular point of the mirror is responsible for any specific part ofthe final focused image.
Unfortunately modern 'laser' image projectors (see below) have some minor limitations. Because they send out the image in an ever expanding focused beam, in focus over some distance, any specific part of the reflecting mirror will relate to a particular part of the viewed image. In this way the laser ceases to be a projector, but an efficient monitor of the state of the reflecting mirror.
Please therefore be advised, that we cannot be responsible for possibly poorer than expected results when using our mirrors in conjunction with' laser' image projectors (LCD and DLP).
'Laser' image projectors
'Laser' image projectors refered to do not only use a lens to focus the image, but send out multiple parallel beams of light. The lens at the front of the system has some effect on the focus, but the critical problem is that the image is composed of a myriad of high intensity, individual, pixel sized beams (see photograph below).
This photograph was taken using an LCD projector, reflecting onto a screen via one of our standard Pilkington 6mm mirrors.
This shows the individual 'pixel' beams of light, used by the projector to make the image.
The slight colour distortion is caused by the lens in the optical system and not the mirror. Mirrors cannot introduce colour distortions.
This is highly magnified and represents only a few square inches/centimetres of the whole screen.
From a normal viewing distance the image looks continuous. However, the formation of the image, many parallel beams of light, is obvious.
