Miniscope V4 - Complete set of components
Founding developer Daniel Aharoni
$1,790.00 USD
e V4 is a leap forward in miniscope technology. It will serve as the platform for a new generation of miniscopes for years to come. This high-end solution will help to advance and disseminate miniature microscopy to the fast increasing open-source neuroscience community.
Significant contributors to the V4 were also the Cai and Shuman labs at Mount Sinai, and the Blair lab at UCLA. It builds on the Golshani, Silva, and Khakh UCLA labs' initiative coordinated by Daniel Aharoni of making Mark Schnitzer's pioneering invention (Nature Methods 2011) open source.
Miniscope V4 uses wide-field fluorescence imaging to record neural activity in awake, freely moving mice. The 'Miniscope V4 - Complete set of components' is an Assembly Kit that includes all the necessary components for those enthusiasts who wish to build a Miniscope V4 unit themselves.
LabMaker also offers a fully-assembled unit, tested, and ready to use. Click here to make your purchase.
It is compatible with the Data Acquisition System (DAQ) with V4 firmware.
KEY FEATURES
- >1mm diameter field of view
- ~1mm working distance
- with electronic focal adjustment of +/-200um with electrowetting lens; no more mechanical sliding in order to focus
- all high resolution achromatic optics (no internal GRIN lens)
- 2.6 grams, 22 mm tall
- absolute head orientation sensor
- requires ~1/5th the excitation power of previous systems
- still uses only a single coaxial cable (down to 0.3mm in diameter) for power, communication, and data.
