With new advances in field of view, sensitivity, wavelength, and sample accommodation, the Ultima 2Pplus delivers an ideal combination of flexibility, resolution, imaging depth and speed, allowing users to perform simultaneous imaging, stimulation and electrophysiology protocols with greater efficiency and effectivity. The system is designed specifically for intravital imaging, with fully motorized control of the objective X-Y-Z position, as well as two axes of rotation for precise imaging orientation. A second scan path enables simultaneous imaging and photoactivation. The system’s optimized optical train confers exceptional performance to the very edges of the large field.
The Ultima 2Pplus field of view is over 50% larger to facilitate modern optogenetics experiments, which require simultaneous imaging and photostimulation of distant regions in a sample. A new, custom optical design preserves spatial and temporal resolution throughout the entire field, which is essential for researchers to be able to continue their work without changing experimental designs.
The Ultima 2Pplus light collection path ensures detection of almost all photons scattered from dim, thick and opaque biological samples. The superior collection efficiency is provided with 2-inch or larger optics
throughout the emission path up to the sensitive close-proximity detectors. As two-photon microscopy has become well adopted, emerging three-photon microscopy offers the potential to image even deeper into
samples. Since further infrared wavelengths are scattered even less, three-photon excitation has the promise to be able to image several millimeters into the brain. Ultima 2Pplus already uniquely incorporates this capability to take your research to new levels of potential.
The Ultima 2Pplus empowers sophisticated optogenetics experiments with Bruker's new Neuralight 3D Ultra Spatial Light Modulator option. Large populations of targets can be stimulated simultaneously in multiple focal planes with computer-generated holograms. During 3D holographic experiments, targets at different depths are imaged with a custom-designed, optically-corrected ETL focusing module that allows for independent Z-positioning of the imaging plane relative to photostimulation.

We have the 2Pplus - the scope is well-designed and the software easy to use. Their scopes are very flexible in design if you wanted to add additional optics, components, or software functionality. Bruker shines with respect to customer service… they have several great service experts who usually respond within a day or two with insightful solutions. Further, the support is highly personalized; not before long after purchasing the microscope, we were paired with specialists who intimately familiarized themselves with our applications.
We appreciate the modular nature of the Ultima hardware and software. The systems now available range from basic imaging systems to the dual-laser photo-stimulation multi-mode imaging workstation. We have continued updating many of our 14 machines, including our ten year old systems. The Team Viewer connection and support is a huge asset for novice owners and for significant software changes.
