Overview

The ”optical multimeter” for probing brain circuits allows you:

  • optogenetic stimulation
  • and fluorescence measurement
  • via the same fiber

The applications are:

  • Localized measurement of physiological fluorescence signals (e.g. Ca2+signals) from multiple sites in stimulation of physiological signals in disease model animals and drug testing freely behaving animals including primates
  • Multi-color optogeneticstimulation
  • Near simultaneous optical measurement of cellular activity and optogenetic stimulation
  • Chronic monitoringof physiological signals in disease model animals and drug testing
  • Enhanced localized photodetection for deep-tissue multiphoton imaging
  • Combined fluorescence recording with fMRI imaging

NEW! Now also available with 2 detectors for dual fluorescence detection as well as a desktop version!!

Features

Features:

  • Dual-band excitation: 
    450 – 490 nm (OGB1, GCamP, ChR2)
    550 – 590 nm (ArchT)
    Fluorescence recording in 500 – 540 nm band
  • short pulses at high power (optogenetics) on top of
  • constant low power illumination (fluorescence)
  • Ultrafast photodetector:
    hight robustness against high-dose irradiation detecting fluorescence signal immediately after optogenetic stimulation with high sensitivity
  • can also be used as supplemental photodetector channel for multiphoton microscopy
  • compatible with multi-mode SMA fibers incl. non magnetic fibers for fMRI
