- This new emitter design promises an increased brightness of up to 30 per cent in applications such as Virtual Reality(VR) based goggles
- The device is based on the implementation of ‘ SurfLight surface emitter chip technology ‘ in IR emitters
- IR emitters and receivers are used in electronic devices as wireless communication modules. These emitters are also used in the development of VR based visual devices. The current VR industry uses this technology for creating eye-tracking systems. These systems help in determining the user’s direction of gaze and eye movements.The emitters radiate light in an omnidirectional path. As the receiver is fixed, the intensity of the received signal is generally low.
Vishay Intertechnology, Inc. recently extended its optoelectronics portfolio with the release of new high-speed infrared (IR) emitter. The company claims that these VSMY series transmitters are capable of radiating all of its light and power out from the top of the chip. Hence, they can increase the intensity of the recieved IR signal at the receiver.
- Comes in a small surface-mounted device (SMD) package
The company told that the device has a size form factor of 2 mm× 1.25mm × 0.8-mm. It is fabricated in a 0805 surface mount package. The device features opaque sidewalls for minimising transmission losses during light transmissions. This eliminates the need for external sensor-holding barriers in VR devices.
Delivers an increased radiation intensity of up to 30 per cent to the IR receivers
It is stated by the company that the device delivers a higher radiant intensity of up to 30 per cent than previous-generation devices. Also, the device can provide a wide operating temperature range of up to 110° Celcius.
According to the company, the device features a ±60° angle of half intensity. It provides a rising and falling time of seven nanoseconds which reduces the response time of a developed system. The device can even work on low forward voltages of up to 1.6 Volts. The current consumption is less than 100 milliampere when working on low voltage modes.
The device is said to fulfil AEC-Q101 guidelines. This makes the device favourable for use in automotive applications. It is also said to be a halogen-free and RoHS-compliant device.
The small size and higher accuracy of the device is one of the key features of the device. The use of this device can benefit applications related to the development of visual aid systems and Virtual reality applications.
