Dhyana 400A

To meet the challenges of ultra-low light detection, high dynamic range and high speed imaging applications, Tucsen has released the newest Scientific CMOS (sCMOS) camera: Dhyana 400A, which represents the most advanced imaging technology in the world. Compared to the traditional cooled CCDs, The Dhyana 400A has advantages of lower noise, higher sensitivity, wider dynamic range, faster read speed and so on, as shown in the table below. The Dhyana 400A is ideally suited for life science, physics, astronomy, etc, where ultra high performance is required. The release of Dhyana 400A brings a new breakthrough in the field of digital imaging.


Low readnoise

High SNR

Ultra-high Sensitivity

High Dynamic Range

High Frame Speed

Ultra-high quantum efficiency



1. Use the 12V8A power supply. 2.Use USB3.0 cable to connect the camera to the PC .Use ISCapture software to control it.


1. Start the software and get the camera recognized, but the preview is all black.

Check whether the anti-dust cap on the camera C-mount is removed. If already removed and attach the camera to the microscope, check whether the lighting path toggle switch to the camera. Then try to extend exposure time and Gain to get brighter images.

2. The imaging scene from the eyepiece is in focus but the live images from the camera are still out of focus.

This is because the camera and the eyepiece are in different focal planes. Can consider to use adjustable adapter to connect camera to the microscope trinocular, the adjust the adapter to make the live image in focus.

3. There are some shadows on the image and the shadows always stay in the same position even the sample is moved.

Possible reasons: 1. The anti-dust film on the camera C-mount is not removed. -- Remove the anti-dust film. 2. Check whether any dirt on the objective. -- Clean the objective. 3. Some dust on the surface of the camera IR filter. -- Clean the camera optical port.

4. Camera frame rate is extremely slow

Possible reasons: 1. Preview resolution is too high. -- Try lower resolution and check the change of the frame rate. 2. Exposure time is too long. -- If need exposure time longer than 200ms, try to use higher gain to get brighter images. 3. Computer issue. -- Computer is very old or the motherboard chipset is Intel 8 Series \ C220 series.

5. Start the software and get the error message: can not recognize the camera or No camera.

Possible reasons: 1. The camera USB cable is not well connected. -- Reconnect the camera again. 2. Check whether the camera is connect to the USB port on the front of the mainframe. If so, then connect it to the USB port on the back of the mainframe. -- The USB ports on the front of the mainframe are the extended ports from the motherboard which can not provide stable voltage and current for cameras. 3. The camera itself needs extra power supply but does not switch on the power. -- TrueChrome is required to switch on power, attach to the PC and then start the software. TCC-6.1ICE is required to plug in power to be recognized by PC. 4. The camera driver is not installed or failed to install. -- Go to the ‘Device Manager’--> ‘Imaging Devices’ and check whether the camera is listed WITH YELLOW FLAG. Then re-install the driver again. If still fail to install driver, please contact camera technical support for help.

6. How to do quick White Balance?

White Balance while attach camera to stereomicroscope: Use a white paper to replace the sample --> Click on ‘White Balance’ to correct the image color --> Remove the white paper and put back the sample. White Balance while attach the camera to the biological microscope: Move the sample slide to the blank area --> Click on ‘White Balance’ --> move back the sample.

7. Whether there is another way to take a picture and record except manual?

When the software is update to V3.6.6 ISCapture or above versions, press F9 key is to take pictures, press F10 is to record. If it is on manual recording mode, press F11 to end the video.

8. In the preview image, the screen appears a lot of interference fringes.

It is because that the frequency between outside of a light source and the sensor is not consistent. You can improve it by increasing the exposure time, reducing the gain, or close the light source such as incandescent lamp, fluorescent lamp.
