4 ports RFMC - GCaMP


Ordering Code:

  • The 4 ports Rotary Fluorescence Mini Cube (RFMC) supports Isosbestic & Functional GCaMP excitations and recordings of respective fluorescences. It is an add-on to the rotor of a dedicated version of our 24-channel Assisted Electrical Rotary Joint. Replacing an optical rotary joint with an electrical one increases collection efficiency and reduces motion-related signal variation.

    • This RFMC has two built-in LED light sources set to low excitation power.
    • The integrated detector has an amplified photodiode circuit similar to that of the Doric Fluorescence Detector.
    • An LED Driver and a Fluorescence Detector Amplifier connect to Rotary FMC via the Assisted Electrical Rotary Joint's stationary part.
    • The RFMC's are easily attached to or removed from a rotary joint. They can be ordered separately or added to an existing system.
