The future of fNIRS.
Available now.
What is LUMO?
LUMO is a high density functional near-infrared spectroscopy (fNIRS) system, capable of diffuse optical tomography (DOT). LUMO provides continuous, high-density multi-distance sampling, reducing false positives with its inherent short-separation channels.
Lightweight and wearable, LUMO requires no optical fibres and is suitable for all ages and environments.
The flexible configuration allows you to instantly switch between different caps and arrays, whilst the unique scalable design allows you to upgrade your LUMO as your research needs change.
TILES
How does LUMO work?
LUMO’s ground-breaking modular design consists of independent hexagonal sensor tiles that can be easily connected into any cap at any location to form a high-density array.

SOFTWARE
Docks are secured to the cap in your chosen array, and connected together using an innovative flexible printed circuit design. Tiles are designed to be inserted into any dock, enabling quick setup.
Light guides are inserted into the base of the docks, helping to comb through hair and make contact with the scalp. All light guides can easily be removed for cleaning or disinfecting and are completely interchangeable.
Each LUMO cap is made from flexible, high-quality neoprene and is designed to ensure maximum subject comfort without sacrificing durability.
Bespoke caps with custom array designs are made to order, exactly to your specifications. Available in all sizes from infant to adult, with cortical coverage ranging from specific regions of interest up to whole head.

LUMO: beyond fNIRS
By allowing measurement channels to be formed from a wide range of source-detector distances across multiple tiles, LUMO provides consistent, even coverage of the brain. With LUMO you can be confident that you will not miss an area of the cortex because of sparse, uneven sampling.
Left: a typical low density optical fibre array consisting of 10 source and 10 detector locations arranged in a square grid design. This provides only 30 fNIRS channels, all with the same source-detector separation of 30 mm.
Right: the 12-tile high density LUMO prefrontal array provides more than 400 fNIRS channels with source-detector separations ranging from 10 mm all the way up to 70 mm. LUMO provides an average cortical sensitivity 100x that of traditional fNIRS.
High-density sampling has been extensively demonstrated to provide more reliable measurements of brain function than traditional fNIRS approaches. Systems that only measure at one distance (e.g. 30 mm) are highly susceptible to signal contamination arising from the scalp.
LUMO provides multiple short-separation channels for every source and detector, which allows the scalp signal to be detected, isolated, and removed. Only with high-density sampling can users be confident that the signal they record is truly from the brain.
Why choose LUMO?
fNIRS has been gaining traction among neuroscientists, doctors, and psychologists as a promising brain imaging technology. However, the application of fNIRS technology has been limited by low image resolution, uneven brain sensitivity, and the need to apply bulky optical fibres to the scalp of every subject.
LUMO changes this.
