High-definition macro to micro confocal imaging
With high-definition wide field of view images larger than 1cm with unprecedentedly high S/N ratios, the AZ-C2+ allows for imaging of whole-mount specimens, such as embryos, in a single shot. It offers a combination of low and high magnification objective lenses, optical zoom and a confocal scanning zoom function, enabling continuous imaging from macro to micro. Moreover, the AZ-C2+ allows deep imaging of in vivowhole specimens.
High-definition macro to micro confocal imaging
The AZ-C2+ enables high-definition confocal imaging during macro observation as well as micro observation.
Sharp wide field of view images with unprecedentedly high S/N ratios allow for imaging of whole-mount specimens such as embryos and large tissue slices that are commonly used in developmental biology andsystems biology studies.
Moreover, the AZ-C2+ offers a combination of low and high magnification objective lenses and a scanning zoom function, enabling continuous imaging from macro to micro with a single microscope.
The macro in vivo imaging capabilities allow for the capture of confocal images that were previously not possible with traditional stereoscopic microscopes.

One-shot whole specimen macro confocal imaging
High NA objectives for macro observation enable fast, high-resolution, single-image capture of a wide specimen area. Because the objectives cover a field of view larger than 1 cm, imaging of embryos during late stages of development and the dynamics of cell populations in whole organs are possible.
[Note] When Plan Apochromat 1x and AZ100 optical zoom 4x are used, the diagonal diameter of the real field of view is 5.3 mm.

The AZ-C2+ can capture wide-field, optical sections at high resolution in a single scan. With a conventional confocal microscope, image stitching is necessary because the field of view that can be captured in a single scan is small.

The AZ-C2+ allows time-lapse observation of the dynamic behavior of cell populations.
Continuous imaging from low magnification to high magnification
With five different objective lenses, optical zoom and confocal scan zoom, the AZ-C2+ makes imaging possible from very low magnification to high magnification. Macro imaging, such as whole-section imaging, and micro imaging, including imaging of a single cell, can be done using a single microscope.
| High magnification imaging offers clear and sharp images of single cells.

Deep imaging of whole specimens
The AZ-C2+ allows imaging deep into the specimen–difficult to achieve with conventional confocal microscopes. The AZ-C2+ efficiently captures fluorescence signals from deep within a specimen in macro and in vivo imaging.
Nerve cells (red) 2 mm beneath the surface of the embryo can be imaged clearly.

Confocal laser microscope system C2+/C2si+ Ready/C2si
The Nikon C2+ series offers the optimum confocal system to meet both your research and your budgetary needs.
C2+: Standard model boasts high resolution, high sensitivity, and high contrast. Suited for single laboratories or large research groups.
C2si+ Ready: Upgrade to C2si+ is possible by adding a spectral detector.
C2si+: Spectral confocal system featuring a 32-ch multianode spectral detector. A spectral bandwidth of 320 nm can be captured in a single scan.

Configuration with spectral confocal system C2si+
[Note] Upgrade to the macro confocal microscope system is through a combination of the C2+ series and the AZ100 microscope. The AZ100M andA1+ series are not compatible.
