disco4 is an innovative technology platform for discrete spectroscopy. It brings flexibility to any application requiring extreme dynamic range of measurement using multiple LED sources and receivers; especially suitable for small variations in signal with ambient light interference.

Engineer your own solution with disco4 or consult with Dialog Devices to determine the optimum configuration. disco4 is supplied with example optoelectronics (4 multicolour LEDs and PiN diode receiver). If you require data acquisition, we can supply a suitable PC card and custom software.

Applications:

Biomedical	Process Monitoring
Pulse Oximetry – up to four wavelengths allows more accuracy. Low perfusion & motion artefact compensation also possible.	Multi-Wavelength Turbidity – Monitoring and Quality Control of Water, Wine, edible Oil etc
Hepatic Function Testing – Remote detection of Indo-Cyanine Green dye absorption by the Liver.	On-Line Process Control – Control of Filtration Systems pre and post filter.
Venous Occlusion Plethysmography – Venous Insufficiency Assessment & reflux monitoring applications.	On-line Liquid Characterisation - Contamination & Colour Assessment such as Dye Industry
Blood Volume Pulse – Multi Channels allows Peripheral Circulation Assessment in Multiple sites.	In-Situ powder Characterisation – Pharmaceutical Powders, Pulmonary Drug Delivery Assessment.
Venous Oximetry – Novel technique for Assessment of Venous Oxygen Saturation.	Particle Counting – Dust Monitoring, Air Quality Control such as Clean Room.
Arterial Stiffness Assessment - pulse transit time, pulse contour analysis, arterial flow indexing	Discrete Source Colour Sensing – Such as the Textile and Paints Industry.
Anomalies in Flow Channels – Detection of unwanted media in tubing, for example air bubbles.	Fluid Particulate Monitoring - Such as Contamination of machine Cooling or Lubricating Oil.
