Oxymon

A user-friendly, robust and flexible fNIRS system.

Oxymon

Measure oxy-, deoxy-, and total hemoglobin concentration changes, optionally absolute concentrations and tissue saturation index in both brain and muscle tissue.

FEATURES

The OxyMon Mk III is a user-friendly and very flexible near infrared spectroscopy system. The system monitors a subject’s local tissue oxygenation non-invasively by utilising the technique of near infrared spectroscopy. 

Highlights

• Stable, versatile and highly sensitive
• Possible to measure on both brain and muscle tissue
• Numerous configurations, from 1 to 100+ channels
• Fast data collection at 50 Hz as standard - up to 250 Hz possible, for any amount of channels
• No need to screen against ambient light
• Unlimited data storage
• The light detector cannot be damaged by ambient light
• Raw data (optical densities) easily accessible
• Up to 4 wavelengths per channel

The technique

Near infrared spectroscopy, (NIRS), the technique on which the OxyMon is based, relies mainly on two characteristics of human tissue. Firstly, the relative transparency of tissue for light in the NIR range, and secondly on the oxygenation dependent light absorbance of hemoglobin.
