Scanning + Photostimulation

Vector™ RS+ hybrid scanner combines the speed of resonant scanning with the flexibility of dual galvanometers.


Rapid switching between 30 fps full-frame resonant scanning and spiral or spot photostimulation.


Pulse-triggered digitization ensures maximum signal collection by syncing acquisition to laser output.

Core components

Computer generated holography

with Phasor

Optogenetic photostimulation and uncaging with the highest available temporal resolution and simultaneous illumination of non-adjacent regions.


Spatial light modulator (SLM) creates a holographic illumination pattern via shapes, hand-drawn regions, and diffraction-limited spots.


Capable of simultaneous stimulation in multiple 3D locations above and below the plane of focus.


Choose from a combination of up to 7 visible wavelengths or a high power fixed-wavelength femtosecond laser for near-IR stimulation and uncaging.


Optional Temporal Focusing for Phasor 2-Photon confines the axial thickness of large illumination regions to < 20 µm.

Rapid 4D imaging

Dynamic, continuous beam diameter and laser power adjustments for optimal signal collection.


Piezo objective collar eliminates delay between frames with continuous, synchronized Z movement.


SlideBook algorithms track the sample in X, Y and Z to maintain focus and alignment.


2P Time Correlated Single Photon Counting (TCSPC)


Fluorescence Lifetime Imaging Microscopy (FLIM)


SlideBook module. Utilizes standard GaAsP detectors or optional hybrid PMT / APD detectors.

Temporal focusing
for 2P Phasor

Disperses laser illumination above and below

unwanted fluorescence excitation and ensuring
Phasor illumination of larger regions or cells deep
in scattering tissue are still axially confined to
the desired target.

Widefield imaging
