Optical Design

MinebeaMitsumi’s optical design team develops technology for LED backlights and lenses. Simulation-bases design and ultra-precision machining technology are used to for development and product manufacturing.

Optical guide plates require uniform light emission across a thin-plate surface. Minebea combines light guide design with advanced, highly complex injection molding technology to produce the world’s thinnest optical guide plates.

MinebeaMitusmi’s experts create lens designs for specific lens applications. Detailed simulation of light behavior makes it possible to design ultra-thin optical guide plates and the LED lighting lenses.

Micro-optical element design is critical to efficiently control light with a thin lens. Elements such as light collection, dispersion, reflection and refraction are evaluated using optical simulation technology.
