Managing Near Infrared (NIR) Light Using Visible Opaque Materials

NIR illumination and detection electronics often incorporate a protective cover or lens that appears black or visibly opaque.  The black cover on the end of a TV remote or a dome around a night vision security camera are examples of visible opaque, NIR transmitting materials.  They obscure electronics and reduce heat from Solar’s visual spectrum while efficiently transmitting NIR portion of light.  They also expand design options and minimize the appearance of welds created by NIR lasers in part joining operations.
