Zeiss Axiocam HR Series

Axiocam HR series


The high-resolution camera for digital documentation

Using our highest-performance camera you can for instance analyze processes in the fields of pathology and developmental biology. You can document your results with the best color reproduction and with every detail retained. Two switchable read-out speeds satisfy every requirement on the scale between high resolution and speed. They considerably expand the possible applications of this camera.

Complete color information at every pixel

A moving sensor evaluates every detail in the red, green and blue channels. Color fringes at fine structures and edges, which occur when using cameras with a fixed sensor, are therefore avoided. Tissue discolorations can be interpreted quickly and reliably with 42 bit RGB color depth and a dynamic range of up to 1: 2500.

All details with up to 13 megapixels

With nine different resolutions you can generate images of the finest cell structures for meaningful presentation.

Fluorescence – Maximum sensitivity on a wide range

The monochrome AxioCam HRm does not need a light-reducing filter mask and allows exposure times of several minutes. It features a resolution noise of less than 7.7 e and allows you to detect even the weakest fluorescence. With the large 2/3“ CCD it is even possible to capture fluorescence with intensities that cannot be perceived by the human eye.

The AxioCam HR patent – Complete color information for all details

A digital 1-chip color camera normally uses a sensor with a color mask. When acquiring a single image with this camera, each pixel only receives the color information for red, green or blue in one place. Missing color information has to be determined by means of interpolation from the neighboring pixels. This leads to images with disruptive color fringes and distorted colors at fine structures.

The patented color co-site sampling technique of the AxioCam HR always supplies complete color information for every pixel. In combination with the resolution-enhancing microscanning process, this allows you to acquire brilliantly sharp color images in extremely high resolution.
