MAGUS CBF70 Digital Camera

USB 3.0, 21MP, 4/3'', color

MAGUS CBF70 is a science camera with 21MP resolution and 4/3" sensor for the brightfield microscopy technique.
The camera delivers a realistic image at a 5280x3954 pix resolution. The camera is recommended for use with 4x, 10x, 20x, and 40x objectives. When working with low magnification objectives, the camera will allow you to see finer details.
At maximum resolution, video is captured at 17fps. It is enough for adjusting the focusing of the microscope.
When the resolution is reduced, the rate increases to 56, 67, and 192fps. Transitions between frames become softer, the camera catches the slightest movement of the sample. These modes are suitable for classroom demonstrations, recording video of fast-moving processes, and observing samples that are moving.
The camera is equipped with a USB 3.0 interface. The data transfer speed is 10 times faster than USB 2.0 cameras. The high-speed camera is recommended for professional laboratories, research, or university training.

The camera is equipped with a SONY Exmor backlit color CMOS sensor. This technology increases light sensitivity and improves camera performance in low-light conditions.
Large sensor – 4/3''. The physical size of the sensor affects the image quality: The larger it is, the cleaner the image will be, and the greater the color depth and the wider the field of view. The 3.3x3.3µm pixel size provides a light sensitivity of 399mV at 1/30s. To maximize the field of view without distortion, we recommend using a 1x magnification adapter.

Software features
The camera uses software to display images on an external display, take photographs, record video, edit images, and measure linear and angular dimensions of objects and their structures. Before taking measurements, the software must be calibrated for each objective with a calibration slide.

The camera is mounted on the microscope in the trinocular tube or side camera port using the C-mount adapter (included). To mount the camera in an eyepiece tube instead of an eyepiece, you will need a special C-mount adapter and adapters to fit the tube diameter (not included).
