The 1293.5001 is a 1-fold Spherical Light Guide for front panel and is the optimum solution when a design calls for a light guide that is not physically attached to the PCB. They push-fit into a hole in the front panel and their light-inject face floats in close proximity to the SMD LED without actually making contact. Such an arrangement provides engineers with multiple design options. Light guides form a key function in the human interface with a product, so their appearance and optical quality have a huge influence on aesthetics and overall perceptions. The options spherical head provide design engineers with ultimate flexibility. MENTOR light guides are visibly superior, premium-quality precision optics that will enhance the appearance of any electronic device.
