Multi-Wavelength Fiber Photometry System
"With multi-fiber photometry, the Multi-Wavelength Photometry System builds on the technology of the legacy single wavelength photometry system and incorporates new features based on customer feedback. This camera based system includes three built in LEDs for excitation and two optical sensors which allow for detection of green and red fluorescence simultaneously and a branching patch cable provides the user with the ability to record from multiple brain regions or multiple animals. The system interleaves the 410 nm and 465 nm LEDS and the camera detecting green fluorescence captures light for each of these wavelengths independently, which allows the user to identify the calcium-dependent fluorescence (isosbestic control)."
