Rapid Multi Region Scanner

The Rapid Multi Region Scanner increases the imaging rate of microscopes by subdividing the field of view into multiple regions of interest. It combines the flexibility of two galvos with the rapidity of a resonant scanner, forming an integrated and compact device. This design allows the scanner to be compatible with several commercial and DIY 2P microscopes, such as the Thorlabs BScope and Sutter MOM.

The scanner's key benefits include:

• Increased imaging rate by focusing on multiple regions of interest, eliminating time wasted on unneeded areas.
• Arbitrary line scanning for sampling individual neurons along predefined paths efficiently.
• Photostimulation capability to quickly stimulate neurons in sequence.

This product features a module that surpasses ordinary resonant-galvo configurations by enabling focused raster scanning within small regions of interest. Users can then maneuver this scanning coverage in both X and Y axes, improving time resolution without scanning unnecessary field areas.

The scanner employs integrated resonant and dual galvo mirrors, which support various mounting options. Key specifications include a Cambridge resonant mirror operating at 8kHz, a field of view of 20 degrees optical, and compatibility with laser beam diameters up to 4mm. It accommodates a wavelength range from 800nm to 1100nm.

The unit includes a controller box with input voltage options ranging from 90-132 V (AC) and consumes a maximum power of 1050 W. It's designed for minimal group delay dispersion, less than 1000fs², and offers a resonant scan angle of up to ±13 degrees optical.

The Rapid Multi Region Scanner provides enhanced imaging capabilities for neuroscientists and researchers, allowing them to achieve high-speed scanning and precise photostimulation in various experimental settings.
