Neurescence -Model Quartet -Miniature Fluorescence Microscope
Quartet is a miniature fluorescence microscope and data collection software package optimized for neuronal calcium imaging.

After connecting the fiber to the lens, the user manually finds the best focus using a key that we provide with Quartet. The design of the connector is such that even when the fiber probe is disconnected the initially set focus remains the same. This ensures the same plane of neurons is imaged as days go by, ensuring any observed changes come from the changes in the neuronal micro-circuitry and not from focusing on a different plane of neurons. This is a capability essential for answering R&D questions about brain and spinal cord neuronal micro-circuitries.
We currently offer two types of GRIN lenses for imaging different areas of the central nervous system. In the picture below, the lens that is in the connector on the top, held by the scientist, is 0.7mm in diameter and more than 8mm long to reach any area of the brain in rodents or larger animals. The lens in the connector near the ruler is 1mm in diameter and can reach areas in the brain which are up to 2.5mm deep.
