Choosing the right Digital Camera for your Microscope.
There are many different types of cameras on the market, not all are suitable for microscopy.
Dedicated microscope digital cameras typically cost more for less resolution than typical consumer cameras, but they have the advantage of being directly controlled by a computer. They typically provide a better preview image, often with focusing aids, and the ability to acquire the image directly into various imaging software packages. They also have better control over exposure settings.
Even within the range of digital microscopy cameras, there are options to consider depending the type of microscopy you are doing.
There are two main types of sensors for the cameras. CMOS and CCD. CMOS cameras are typically lower in cost than CCD cameras with similarly sized sensors. However, CCD sensors perform much better in lower light situations ( eg. fluorescence ).

There is also the size of the sensor to consider. The main ones are 1/3", 1/2", 2/3" and 1". The larger sized sensors generally cost more, but will give you better quality images since more light will fall onto the sensor. The other advantage of larger sensors, is that it will give you a bigger field of view. The sensor under 1", will typically need additional optics in the microscope coupler, in order to get a similar field of view. The additional optics are never perfect, and sometimes cause vignetting/shading around the edges.
