Multiphoton microscope OptoVolt

opticalinspectionfor micro-imaging applications

Bruker's OptoVolt™ Module for Ultima 2Pplus multiphoton microscopes delivers unprecedented kilohertz imaging rates to enable voltage imaging neural research. It provides a significant improvement over standard imaging techniques by capturing electrical dynamics at up to 1,000 frames per second and providing software-selectable multiplication modes. These accelerated imaging speeds allow neuroscientists to capture millisecond dynamics of cell-to-cell neural communication, and with the emergence of fluorescent voltage indicators, it is even possible to measure neural activity with higher temporal resolution than fluorescent calcium indicators have allowed. Multiplication Optics Enhance Speed and Resolution OptoVolt contains multiplication optics that re-route the resonant scanning beam for customized aspheric microlens arrays. It also leverages large detection optics for collecting scarce photons, in vivo and deep into tissue. This module multiplies up the scan speed with the microlens array and the resulting multiplication factor is based on the number of microlenses scanned across. It is seamlessly integrated with the 2Pplus, and is selectable as a scanning mode for ease-of-use. This gives researchers fast and flexible imaging for a range of novel experiments, including single-cell electrophysiology and wide-field calcium imaging. Researchers can build upon their existing microscope system as their research develops. Without the voltage imaging module, it scans one line every time it sweeps.So, it sweeps one line, and then this is repeated for however many lines are wanted to create an image. With the scan multiplier technology,
