Photon Spectroscopes
Designed for science
Cortivision PHOTON is the main family of Cortivision spectroscopes. They are mobile, wireless, resistant to external interference and can be easily integrated with other technologies.
Photon Cap
Cortivision PHOTON CAP is a wireless near infrared spectroscope (NIRS) for the functional measurement of the hemodynamic response of the brain. Our device enables non-invasive monitoring of the activity of selected areas of the cerebral cortex, thanks to a set of high-quality emitters and detectors.
Cortivision PHOTON CAP is the first fully integrated environment to combine NIRS technology with Virtual Reality (VR) for scientific research and training applications. The use of virtual reality allows for unprecedented control of the content that we provide to the test subject. For this reason, PHOTON CAP is a perfect tool for scientists and professionals in the field of UX / UI and ergonomics. The system provides easy integration with any stimulus presentation software, as well as convenient signal export to the most popular recording formats (including .nirs).
The built-in IMU (inertial measurement unit) module allows you to easily read the movement parameters during the test based on the indications of the accelerometer and gyroscope.

Photon CAP light
The first step to the adventure with fNIRS
We believe that Light version of Photon Cap is a very good start with fNIRS for any researcher who doesn’t feel very strong in NIR spectroscopy. Easy, uncomplicated montage options, simple research paradigms and ease in organisaing space on the head makes it perfect to start.
As a part of a journey this device can be later extended to a full Cap C20. It means that purchasing Light version leaves the door still open for a more comprehensive version of the system in the future.
