Marktech Optoelectronics Announces Multi-wavelength Emitters, Detectors and LEDs for Wearables
For wearable designs requiring more advanced onboard monitoring and detection capabilities, Marktech announces a number of multi-wavelength emitter-detector combinations. These combinations may be integrated into a single package along with a multi-wavelength range detector. In addition, Marktech’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. These Marktech LED emitters can be further optimised for low power consumption and increasing 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 colour temperature and CRI are available, as well as lower-profile direct-attach (DA) type chip packages.
