Never look at the sun, a bright light source, or laser beam through the camera. It can cause permanent damage to your eyes.
MAGUS high-speed HDMI cameras are designed to be paired with a digital microscope. Sony Starvis high-sensitivity sensor ensures perfect color reproduction and image quality even in low light conditions. You can install the camera software to view, save, and  edit captured images and videos. The rugged aluminum housing is designed for operation at low temperatures (–10°C).

CAMERA INSTALLATION

HDMI

1. Use an HDMI cable to connect the camera to an HDMI monitor (1).
2. Connect a USB mouse to the connector (2).
3. Insert the memory card into a memory card slot (5).
4. Connect the camera to the power supply (4). Turn the camera on (6).
5. Turn the monitor on and watch videos in the built-in program.
   Use your mouse to control the camera.

USB
CONNECT THE CAMERA TO A PC/LAPTOP

1. Install the MAGUS View software from the USB flash drive (included in the kit) on the PC.
2. Connect the camera to the power supply (4). Turn the camera on (6).
3. Connect the camera to a PC with a cable by inserting one plug into the connector (2) and the other plug into a USB port on the PC.
4. Open the MAGUS View program. The camera will be automatically recognized by the operating system.
   When the USB cable and the mouse are connected to the camera at the same time, the mouse will be unavailable. When the USB cable is disconnected from the camera, the mouse can be used normally.

CALIBRATION USING A CALIBRATION SLIDE

You should use a special stage micrometer (calibration slide) to determine the linear dimensions (in millimeters or microns).
The calibration slide is a transparent glass (of the same size as the specimen slide) thathas a micrometer scale with a scale division of 0.01mm etched on the surface.
The calibration slide (stage micrometer) is used to calibrate the image analysis software for measurements in actual units. In the calibration mode, you should capturean image of the micrometer scale with every objective magnification and indicate the known  distance. That lets you establish a scale of the image in actual units (micrometermillimeter, etc.).

Calibration:

1. Place the calibration slide on the microscope stage.
2. Select the required objective and set the maximum camera resolution.
3. Get a contrast image of the scale on the monitor screen and capture the image.
4. Select the ”Calibrate” function in the software you are using.
5. Double-click on the maximum visible distance and enter the value in actual units.
6. Enter the calibration setting and check the result. The program will save the calibration factor.
7. You can select any measurement unit later, and all the results will be re-calculated in accordance with this selection.

CONTROL PANEL

To open the Camera control panel, move the mouse cursor to the left of the window. The control panel will automatically pop up.

| Snap| Captures the image and saves it to the SD card.
Record| Records a video and saves it to the SD card.
Auto Exposure| Automatically adjusts the exposure time and gain according to
the exposure compensation value.
Exposure Compensation| Available when Auto Exposure is selected. Adjusts the
exposure compensation according to the current video
brightness to achieve the proper brightness value.
Exposure Time| Available when Auto Exposure is not selected. Adjusts the
time of exposure and thus adjusts the brightness of the video.
Gain| Adjusts the brightness of the video. The Noise will be adjusted
accordingly.
Red| Adjusts the proportion of the red color in RGB in the video.
Green| Adjusts the proportion of the green color in RGB in the video.
Blue| Adjusts the proportion of the blue color in RGB in the video.
Auto White Balance| Adjusts the White Balance of the video continuously.
Manual White Balance| Adjusts the Red color or Blue color parameters to set the White Balance of the  video.  White balance is adjusted to obtain a natural ratio of cold and warm colors  on the image with regard to the light source type. Move the corresponding sliders to adjust the values.
ROI White Balance| Adjusts the white balance of the Region of Interest when the Region of Interest  content is changed.
Sharpness| Adjusts the Sharpness level of the video.
Denoise| Removes the noise from the video.
Saturation| Adjusts the Saturation level of the video.
Gamma| Allows you to adjust the midtone values of the image. The higher the Gamma value  is, the darker the image will be.
Contrast| Adjusts the Contrast level of the video.
DC (Direct current)| Allows you to use a light source without light flickering.
AC(50HZ)
(Alternative current)| Eliminates light flickering when a 50Hz light source is used.
AC(60HZ)
(Alternative current)| Eliminates light flickering when a 60Hz light source is used.
Default| Restores the default settings.
