Leading companies today produce and provide advanced digital cameras that are meant specifically for the microscope. Full HD image resolution, elimination of distortion, noise reduction, grain sensitivity, and positional navigation are only some of the advanced features that you may find in the microscope digital cameras being sold online.
A complete kit
When you buy a digital microscope camera you not only are offered advanced camera but also get a complete kit that has many different accessories associated with the camera. These include the microscope camera USB port, a cable through which you can attach the camera to a laptop or computer, and a camera stand, among others.
The different categories of digital microscopic cameras
While the basic technology involved in all the digital microscopic cameras (a lens projecting the image on a pixel array, which is recorded) is the same, there are different categories of digital microscopic cameras present. These include:
CCD: a mature technology, the CCD (charge coupled device) cameras involve reading of all the pixels through a singular output. While this technology works well for the brightly lit images, it may not provide the desired results in dim light. Hence the camera does not suit the fluorescent conditions and applications. Fortunately, some new options are quite fast and work at much faster frame rates while using large amounts of data.
cMOS: cMOS or (Complementary Metal Oxide Conductor) technology ensures that there are many different data outputs present. While the data is itself transferred slowly the multiple points, it enables it to be transferred at a much faster rate. This culminates into a reduction of noise.
EMCCD: Electron multiplication CCD or EMCCD technology involves amplification of signals and even the single photons can be easily detected. A camera can heat itself and the sensor may judge this heat as a signal thereby causing dark signals. The technology provides for preventing of dark signal. Cameras with this technology should be used for the fluorescent applications with low light.
Compatibility
The compatibility of the digital camera with your existing microscope is also very important as you would not like to suffer from deviations. While the new cameras can be easily adjusted with a range of microscopes and provide for easing recording and transmittance of data to your computer screen, you still need to read the product description carefully. Picture clarity is another very important aspect that you should keep in mind and the adaptable camera should provide to you clear images of your specimen that can be easily analysed and probed. The cameras may also come with the illumination capabilities but you need to know more about this by asking the supplier.
Cost involved
The CCD digital cameras may start at a cost of around USD 3000 and upwards. The other technological cameras usually cost more. You can browse through a few online websites and try to know which ones are offering a greater discount. You can also contact the supplier for bulk orders and these orders are usually provided with more discount.
It is important to know the purpose for which you are going to buy a digital camera and a USB digital microscope if you want to make a value-for-money purchase. Different cameras may have different capabilities towards handling the fluorescence and heavy light conditions, and some may offer you the best of both worlds.
I am not great with cameras!
