Vixar announces 850nm and 680nm VCSEL Arrays
Suitable for 3D scanning, gesture recognition sensors, security systems and medical scanning
Vixar, a US supplier of red and near IR VCSEL devices and subassemblies, has announced a family of high power VCSEL arrays for consumer, medical, industrial and automotive applications.
The arrays are available for 850nm and 680nm wavelengths and optimised for output power ranging from 50mW to 10W.
Applications include 3D scanning, gesture recognition sensors, IR illumination for security systems, medical scanning and medical low light laser therapy.
According to the company, the VCSEL arrays combine high power, high-energy efficiency, narrow spectral width, narrow beam divergence, low speckle, and high reliability characteristics into a single miniaturised light source.
Advantages includes high modulation speed for time of flight sensors, high efficiency for mobile devices, simultaneous narrow spectrum and low speckle for noise reduction in illumination sources. Custom die layout, packaging, and integration with optical elements such as diffusers or lenses can be tailored to the customer's application.
"In parallel with the product design we have established a production capability and supply chain that allows us to ship several million units per month of these high power arrays," said Klein Johnson, CTO and co-founder of Vixar.
