This new collection of innovative rear-mounted light guides is an exciting addition to MENTOR’s range of panel-mounted light guides. Conventional front-mounted light guides will by definition always have heads slightly larger than the enclosure’s hole, which results in not all of the head being directly illuminated by the LED. The advantage of mounting from the rear of the panel is that all of the light guide head is directly illuminated and this produces a markedly superior lighting effect. Mechanical fixing is achieved via the radial compression of slightly over-sized rings moulded into the light guide body. The minimum recommended thickness of the front panel is 1.5mm.

As well as the standard stocked part numbers, custom versions with different Dimensions A & B can be provided. Versions using a special diffusing material to produce a frosted effect are available, as is self-colouring of the light guides. The latter allows the potential illuminated colour to be shown even when the LED is in an "off" status. Multiple array versions of these light guides have also recently been introduced." target="new"> of these light guides have also recently been introduced.
