Système de microscope multiphotonique
Robust multiphoton system tailored for in vivo applications
Nikon’s multiphoton confocal microscopes, which clearly visualize fine structures deep within living organisms, have evolved even further. The AX R MP, equipped with a high speed high resolution resonant scanner, can capture dynamics that span a wide area with superior spatial and temporal resolution. In addition, a greatly expanded sample area provides the flexibility needed to observe biological samples in their natural positions and accommodates additional equipment often required for in vivo imaging.
The AX R MP maximizes image size, as well as spatial and temporal resolution, providing a uniquely powerful solution for any multiphoton experiment.

Bigger pictures. Fast.
Featuring a 22mm field-of-view for both resonant and galvano scanners, the AX R MP captures more data in every frame at any magnification. This means less time spent imaging large specimens and more information in every frame.
See more at high magnification
Use the AX R MP field of view and Nikon's world-class objective lenses to capture large specimens in one image. With resolutions up to 8K x 8K, these images can be captured without sacrificing a single detail.
Redesigned optics maximize performance over a large area and deliver seamless image stitching at much higher speeds. These improvements save time during acquisition and minimize post-processing.
High-speed imaging that captures the dynamics of life
The 2K x 2K resonant scanner featured on the AX R MP provides fast (up to 720 fps), gentle and high resolution imaging. This means samples live longer and stay healthier all while much higher-quality data is being collected. Alternatively, the resonant scanner can be applied to large fixed samples to dramatically improve the speed of large volume acquistions, with no loss of image integrity.
Bright, high-definition imaging of deep structures
Utilizing high-resolution resonant scanning, extremely low-noise detectors and efficient multiphoton excitation, the AX R MP collects fluorescence from deep within any specimen for bright, high-definition results.

The AX R MP maximizes signal collection by placing detectors as close to the sample as possible. Sensitivity is improved by utilizing the latest electrical and detector designs to drastically reduce noise that normally obscures dim signals. Detector configurations are flexible allowing the system to be tailored to any experimental needs.
Space to expand
The AX-FN series of microscopes prioritizes flexibility and free space under the objective. This means experimental design is limited only by the users’ imagination, rather than the body of the microscope.
The motorized upright microscope dedicated for AX R MP provides up to 40 cm under the objective in two unique configurations. Both stands provide a large amount of free space around the sample improving positioning, flexibility and accessibility.
A system built for intravital microscopy
The AX R MP is designed from top to bottom to deliver maximum performance and flexibility for intravital imaging. Built to be fast, without sacrificing image quality, this system delivers reliable data in even the most difficult conditions. With unique AX-FN microscope stands, space is prioritized allowing access to new experimental designs and samples. Auto-alignment brings day-to-day reliability that is absolutely essential when precious intravital data is being collected.
Accommodate any sample
Experiments are best performed with minimal disturbance to the sample. Utilizing Nikon's new CFI75 tilting nosepiece, the objective can be oriented to image samples in their natural positions, minimizing stress and uncontrolled variables. This nosepiece is compatible with Piezo Z, maximizing 3D image speed in these challenging samples.
Support for visible light imaging
The AX R MP supports observation not only at infrared wavelengths, but also at visible wavelengths. It enables both multiphoton imaging and confocal imaging with a single microscope. It also enables simultaneous photostimulation and imaging using two different wavelengths.
Opti-Microscan photostimulator (optional)
Photostimulation using wavelengths* of 400 to 700 nm enables simultaneous visible light stimulation and IR imaging. Stimulation modes include simultaneous, sequential, and manual stimulation.
* Limited by the specifications of the filter cube used.
DUX-VB high-sensitivity visible light detector unit
The transmission wavelength band of the LVF (Linear Variable Filter) employed in the DUX-VB gradually changes depending on its location, enabling continuous tuning of the wavelength detection setting within a range of 400 nm to 750 nm. From 2 to 4 channels can be selected, and high sensitivity GaAsP PMT can be used for all channels.
