ROHM optical components

ROHM SMD LED

ROHM's LED (Light Emitting Diode) is divided into red to blue LED, with a wide variety of colors available. ROHM LED has many characteristics, such as miniaturization technology and high heat dissipation, high heat resistance PKG deployment, and promotion of internal manufacturing of LED components. Surface mount LED (monochrome type): ROHM's surface mount LED has a rich lineup of small, high-power, side emitting, and back mounted types. Surface mounted LED (multi-color type): ROHM's multi-color surface mounted LED has a rich lineup of small, high-power, side emitting, and back mounted types. LED lights (monochrome type): ROHM's LED lights have a wide range of product types, including 3 * 5 * types, used for high brightness and high reliability outdoor displays. Phototransistor: commonly used in small precision instruments with high reliability and sensitivity, it is a phototransistor paired with infrared light-emitting diodes.

ROHM LED display

ROHM produces a variety of LED displays with excellent visual recognizability and reliability, including high brightness LED digital displays and LED dot matrix units. LED digital display: LED digital display is a digital display module specifically designed to display digital information. The shape of the displayed numbers is equipped with light-emitting diodes, so the visibility is very good.

ROHM laser diode

ROHM Semiconductor has a wide range of laser products, which can be widely used in devices such as optical discs, printers, sensors, etc. High output semiconductor laser diode: a high output infrared laser diode characterized by high peak output using pulse lighting. Can be used as a light source for distance measurement. Maximizing the direct and focused characteristics of laser diodes has the potential to expand into automotive fields such as LiDAR (Light Detection and Ranging). VCSEL： Vertical resonator surface emitting laser diode. The vertical cavity surface emitting laser resonator is formed in the vertical direction of the semiconductor component circuit board, thus having the characteristic of emitting laser light perpendicular to the circuit board. Red frequency band laser: The production of semiconductor laser products with a Rom wavelength of 780nm is abundant. It can not only be used for playing CDs, but also widely used in sensors and other devices.

Red/infrared dual wavelength laser tube: ROHM's dual wavelength semiconductor laser products have abundant production. We have a product lineup for playing CD/DVD. Red band laser: The production of semiconductor laser products with a ROHM wavelength of 660nm is abundant. It can not only be used to play DVDs, but also widely used in devices such as sensors and barcode readers. Multi beam laser: The production of multi beam semiconductor laser products for ROHM printers is abundant. ROHM has mass-produced dual beam laser products with a wavelength of 780nm, and is currently developing 780nm 4-beam and 660nm 2/4-beam laser products.

ROHM optical sensor

ROHM's light sensors include multiple varieties such as high sensitivity and high reliability phototransistors, infrared light-emitting diodes, etc. Illumination proximity integrated sensor: It is a module that integrates proximity sensors, infrared LEDs, and illumination sensors into one chip, which can improve the overall power saving performance and image visibility of the machine. Transmission type optical chopper: It is an optical switch that detects the presence or absence of objects by blocking light, and can be widely used in fields such as position detection and rotation detection. Reflective optical sensor (optical mirror): a form of detecting the presence or absence of an object based on the reflection of light by the object being detected. Infrared light-emitting diode: It is an infrared light-emitting diode suitable for various devices such as remote control transmitters and optical communication. Photodiode: ROHM's photodiodes are used in small precision instruments and are available in surface mount form (side view, top view).

Phototransistor: commonly used in small precision instruments with high reliability and sensitivity, it is a phototransistor paired with infrared light-emitting diodes. 4-way detection sensor: It is an optical 4-way surface mount detection sensor conceived according to new thinking. Because it is an optical type, it is less affected by vibration compared to a mechanical type; Compared with the magnetic type, it is not affected by magnetic fields, so it can accurately detect four directions: up, down, left, and right. Illuminance sensor IC: The ROHM illuminance sensor IC has optical characteristics similar to human vision. It achieves low power consumption (environmentally friendly design) and improves visibility (recognizability) through the automatic dimming function of the display backlight.
