Multi-wavelength Emitters, Detectors & LEDs Outfit Wearables

Marktech Optoelectronics unveils its dedicated offerings for wearables that consist of standard and custom emitters and detectors, in both multi-wavelength and hybrid designs and in UV, visible, infrared, and SWIR ranges. Some of the most common wearable applications supported by the components 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, the company offers several multi-wavelength emitter-detector combinations. These can be seamlessly integrated into a single package along with a multi-wavelength range detector.

Additionally, silicon and InGaAs photodetectors may be similarly combined with GaP Schottky UV photodiodes, creating an expanded spectral detection range of approximately 150 nm to 1,750 nm. Optoelectronics assemblies are available in plastic, ceramic, and glass-to-metal (hybrid) package types. Several options are also available to effectively address specialty requirements for hermetic sealing, temperature extremes, and humid or moisture-rich environments.

 

Marktech’s high-brightness LEDs and LED emitters can be 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 emitters can be further optimized for low power consumption. 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.
