Marktech announces multi-wavelength emitters, detectors and LEDs for wearables

Marktech Optoelectronics of Latham, NY, USA has launched its dedicated product range for wearables. The firm says that its standard and custom emitters and detectors – in both multi-wavelength and hybrid designs and in UV, visible, infrared and short-wavelength infrared (SWIR) ranges – are routinely specified within consumer- and hospital-grade flexible, stretchable and wearable devices. Some of the most common wearable applications supported include consumer-grade fitness trackers; high-end cardiac, oxygen and blood pressure monitors; audiological diagnostic devices for detecting inner ear abnormalities and damage; non-invasive optical chemical sensing; and indoor/outdoor UV-level detection.

For wearable designs requiring more advanced onboard monitoring and detection capabilities, Marktech offers multi-wavelength emitter-detector combinations that can be integrated into a single package along with a multi-wavelength range detector. In addition, Marktech’s silicon and indium gallium arsenide (InGaAs) photodetectors may be similarly combined with its gallium phosphide (GaP) Schottky UV photodiodes, creating an expanded spectral detection range of 150-1750nm. Optoelectronics assemblies are available in plastic, ceramic and glass-to-metal (hybrid) package types. 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 of 280-1720nm, with expanded wavelengths by special request. The LED emitters can be further optimized for low power consumption. Such optimizations can result in increased wearable device battery life, while still maintaining required output levels. Operating currents of 2mA or less are also possible. In applications requiring the incorporation of a white LED, an assortment of color temperatures and color rendering index (CRI) are available, as well as lower-profile direct-attach (DA)-type chip packages.

All design and testing of optoelectronics components and assemblies is conducted at Marktech’s worldwide R&D center in Latham (Albany), where it can design, develop and test optoelectronics components to customers’ standards.

Marktech says that each new wearables design draws on its own portfolio of related success stories and applies the acquired value-added expertise of lessons learned. Wearable optoelectronics components can be produced in almost any sized quantity, from prototype to OEM volumes. The firm 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.
