New Multi-wavelength Emitters, Detectors and LEDs for Wearables

Posted Dec 05, 2018 by Marktech Optoelectronics

Leading developer of standard and custom optoelectronics components and assemblies, Marktech Optoelectronics has released new offerings for wearables. Marktech’s standard and custom emitters and detectors, in both multi-wavelength and hybrid designs and in UV, visible, infrared, and SWIR ranges, are routinely specified within consumer- and hospital-grade flexible, stretchable and wearable devices. Some of the most common wearable applications supported by the company include consumer-grade fitness trackers; high-end cardiac, oxygen, and blood pressure monitors; audiological diagnostic devices; non-invasive optical chemical sensing; and indoor/outdoor UV-level detection.

For wearable designs requiring more advanced onboard monitoring and detection capabilities, Marktech is now offering a number of multi-wavelength emitter-detector combinations. These combinations may be seamlessly integrated into a single package along with a multi-wavelength range detector. In addition, the company’s Silicon and InGaAs photodetectors may be similarly combined with its GaP Schottky UV photodiodes, creating an expanded spectral detection range of approximately 150 nm to 1750 nm. Optoelectronics assemblies are available in plastic, ceramic, and glass-to-metal (hybrid) package types. A number of options are also available to effectively address specialty requirements for hermetic sealing, temperature extremes, and humid or moisture-rich environments.

In addition, Marktech high-brightness LEDs and LED emitters are routinely specified for wearable displays and remote physiological monitoring requirements. Standard LED emitters are offered in wavelengths from 280 nm to 1720 nm, with expanded wavelengths by special request. The new Marktech LED emitters can be further optimized for low power consumption resulting in increased wearable device battery life, while still maintaining required output levels. The achievement of operating currents of 2 mA or less is also possible. In applications requiring the incorporation of a white LED, an assortment of color temperature and CRI are available, as well as lower-profile direct-attach (DA) type chip packages.

All design and testing of Marktech optoelectronics components and assemblies is conducted from the company’s worldwide R&D center in Latham (Albany), New York, USA. There, it is able to design, develop and test optoelectronics components to customer exacting standards. Each new wearables design draws upon its own vast portfolio of related success stories and applies the acquired value-added expertise of lessons learned.

Wearable optoelectronics components from Marktech may be produced in virtually any sized quantity, from prototype to OEM volumes, with competitive lead times. The company also has the necessary full in-house capabilities to perform complete electrical and optical characteristics testing, from die-level to finished product designs, as well as complete end-to-end examinations of related components and assemblies. Wearables-specific applications engineering support is also available.
