ROHM Optical Sensors

ROHM's optical sensors include high sensitivity, high reliability phototransistors, infrared light emitting diodes, transmission type photointerruptors and reflective type photointerruptors.

›Optical Proximity Sensors and Ambient Light Sensors

This module includes optical proximity sensor, ambient light sensor, and infrared LED. It enables lowering current consumption and/or improving the screen visibility under the bright environment.

›Reflective Type Photosensors

This is the type for judging existence or absence of an object by detecting the reflection from such object with casted light.

›Photo Diode

ROHM photodiodes have been adopted in a variety of compact precision equipment. Both side view and top view types are available.

›4 Direction Detector

This is a surface-mount optical type 4-directional sensor based on the new concept ”Optical” solution. This device get less influences from vibration than the mechanical type device and is also free from magnetic influence unlike the magnetic type device: so that this device detects up/down in four directions accurately.

›Transmission Type Photointerrupters

Optical switches which detect existence/absence of object(s) by intercepting of light, suitable for various applications like sensing of position or speed of rotation, etc.

›Infrared Light Emitting Diodes

Infrared LED suitable for the remote-controller & optical communication equipment.

›Phototransistors

High reliability/sensitivity photo-transistor to be used with infrared LED in pairs popularly used in compact precision instruments.

›Ambient Light Sensor ICs

ROHM ambient light sensors feature optical characteristics close to the human eye, enabling automatic backlight adjustment in displays for lower power consumption and optimum visibility.
