Custom Light Guide and Light Pipe Design
MENTOR’s standard range offers a diverse spectrum of ultra-high-quality standard light guides. It includes front-panel mounted designs as well as horizontal light guides or vertical PCB-mounted light guides, single and multiple light guides, bargraph indicators, different head shapes and varied lengths including miniaturised solutions and flexible light guide systems.

Despite this enormous range, custom light guides are occasionally the optimum solution. For example, when a specific radiating characteristic is required, the modification of a PCB or front panel is difficult to achieve or a totally new lighting design is needed, MENTOR is the obvious first port-of-call.
