Macro Confocal Microscope System

Large field of view macro confocal imaging system.

The AZ-C2+ enables high-definition confocal imaging during macro observation as well as micro observation. Sharp, wide field of view images with incredibly high S/N ratios allow for imaging of whole-mount specimens such as embryos and large tissue slices that are commonly used in developmental and systems 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.

Key Features

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 capturing 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.

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+ efficiently captures fluorescence signals from deep within a specimen enabling deep imaging for both macro and in vivo imaging.

Cancer 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.

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.

Spectral confocal system featuring a 32-ch multianode spectral detector. A spectral bandwidth of 320 nm can be captured in a single scan.

[Note] Upgrade to the macro confocal microscope system is through a combination of the C2+ series and the AZ100 microscope. The AZ100M and A1+ series are not compatible.
