Objective Changer

Simultaneously image and photostimulate hundreds of individual cells in 3D, with precise targeting of cells across large areas of the brain. Introducing the HoloStim-3D.

Objective Changer

The Objective Changer allows a seamless way to change objectives, enabling easy switching between high and low magnification.

It is ideal for use in electrophysiology experiments, where a low magnification objective is required for gross positioning of the pipette and a larger magnification is required when approaching a cell.

Compatible with the Scientifica SliceScopeMDU (Multiphoton Detection Unit) and LASU (Laser Applied Stimulation and Uncaging) system. It is suitable for use with air and water immersion objectives. 

Objective Changer
Keep your sample in focus

Parcentricity is maintained when switching objectives, ensuring structures remain in the field of view.

Smooth switching of objectives

Seamless transition between two objectives, ideal for electrophysiology experiments.

Small profile

The small profile increases experimental space, allowing placement of other equipment around your sample.

Compatible with all contrast techniques

Including Differential Interference Contrast (DIC), Dodt Gradient Contrast, Oblique contrast and Phase contrast.
