ROHM Semiconductor Optoelectronics

LEDs

ROHM Semiconductor LEDs feature chip LEDs (mono-color type and multi-color type), LED lamps (mono-color type), and infrared light-emitting diodes. This lineup includes a wide range of product groups for any user's needs.

The CSL1104WB High-Intensity Reflector Type White LED is a white LED that achieves a high luminous intensity of 2.0cd in an ultra-compact 0603 size. This ultra-compact product contributes to the space-saving of applications. Since high-density mounting is possible, it also improves the design, such as enabling blackout expression of panels. The SMLP14WBCN1W High Brightness White Chip LED is 1006 (0402) size ultra-compact white LED. Original device technology allows high brightness.

Laser Diodes

ROHM Semiconductor Laser Diodes offer rectilinearity, monochromaticity, coherence, condensation, and pulse response characteristics of laser light that allow the diodes to be used in optical discs (optical pickups: OPU), laser printers, multi-function equipment, and more. The broad lineup of laser diodes are optimized for a wide range of applications.

The RLD63NPC5 is 635nm single mode laser diode for sensor, bar-code scanner, leveling, ranging. The RLD90QZW8 Invisible Pulsed Laser Diode realizes a longer detection distance and improved sensing accuracy due to its narrow emission width. The RLD94SAQ6 Infrared VCSEL is characterized by having a monomodal beam shape with excellent coupling with fibers and lenses. The RLD94SAQ8 VCSEL is a product with small PCE change over temperature and the beam spread angle can be selected from several types of lineup. The RLD90QZW3 (75W, 225μm), RLD90QZW5 (25W, 70μm), RLD90QZW6 (25W, 50μm) Invisible Pulsed Laser Diodes realize a longer detection distance and improved sensing accuracy due to its narrow emission width.
