Emitters, Detectors and LEDs for Wearables.

Marktech the designer and manufacturer of standard and custom optoelectronics components and assemblies, including UV, visible, near-infrared (NIR), and short wavelength infrared (SWIR) emitters, detectors, InP epiwafers and other materials, has announced its dedicated offerings for wearables.

Their 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 Marktech include consumer-grade fitness trackers; high-end cardiac, oxygen, and blood pressure monitors; audiological diagnostic devices, used to detect 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 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, their 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, their 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 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. The achievement of operating currents of 2 mA or less are 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.
