Digital Cameras
Our digital cameras for microscopic applications are available in a variety of styles for cell imaging, industrial, and engineering applications. We carry low-end and high-end cameras that all come with a 1-year warranty.
Select from a huge range of low price, digital microscope cameras, USB 2.0 or 3.0 colourful / monochrome microscopy or telescope camera with CCD, CMOS, scientific CMOS, high-definition or HD, small or large sensors from 1/3″ to 1″ and even 2-in. These are ideal for capturing images or video or displaying video on a monitor in microscopy applications.
Comparison: CCD vs. CMOS Technology
On a CMOS-chip (ComplementaryMetalOxideSemiconductor)eachPixelofthesensorhasit ́s own electronics next to the light sensitive element, which converts the electrons into the digital number.
The CMOS sensor digitizes the electrons of each pixel next to the pixel and supplies the digital value.
On a CCD-chip (Charge-coupled devices) the light sensitiv arey of each pixel next to each other. Transfer and digitazation of the electrons created throug light is done via shifting the electrons through one electronic path.
The CCD shifts one whole row at a time into the readout register. The readout register then shifts one pixel at a time to the output amplifier.
Because of this different architechture the following features come out:
|

CCD |
CMOS |
|
Sensitivity |
Higher fill factor means higher light sensitivity. The light sensitive elements are in the surface of the sensor.
Electronic shutters reduce the aperture only slightly. |
Lower fill factor means lower light sensitivity, because circuits are integrated in between the pixels.
The required transistors for global shutters reduce the aperture. |
|
Image Quality |
Better uniformity as the same electronic generates the value for each pixel. Only a few transistors are involved and generate lower noise. | Each circuit has its own characteristics, which generates fixed pattern noise in the image. Several transistors with individual differences generate higher noise. |
|
Windowing |
Always the whole sensor needs to be read out. | Single pixels can be addressed. |
|
Speed |
Higher read out clock reduce image quality of a CCD chip. Image processing is done outside the chip. | Clocking and digitization is done in the CMOS-chip, image processing can be done also inside. |
|
System design |
Good electronics around the CCD is necessary to get good images. Electronic affects the image quality directly. | Digitization is done in the CMOS-chip itself. You need less and easier components around. Image quality is mainly influenced by the chip. |
–> CCD sensors provide higher image quality
–> CCD sensors are more light sensitive
