When there is a problem of the choice of a chamber for shooting in the light field (blood dab, a histologic preparation, a native preparation), increases on which shooting will be made can be absolutely different. Specification of the image on each increase will also be various, so, permission of a matrix of a chamber in each case has to provide the maximum specification.
All of us got used that in our mobile phones cameras 5-12 Mpiks are mounted, but for microscopy the principle "the more - the better" does not work.
According to Nyquist's criterion, for ensuring the best specification, not less than 2 pixels on a chamber matrix have to fall on each pixel of the image. The more increase, the is less field of vision. So, on a lens 4x, for due specification, the chamber has to have permission not less than 3 Mpiks, and at a lens 100x - no more than 1,4 Mpiks.
We can use a chamber of higher resolution for shooting on big increase. Specification from it will not increase, and here the size of the image and time of shooting will increase. For example, the USB chamber with the resolution of 10 Mpiks gives 4-5 frames per second in the live image that slows down our work in difference from camera 1.4 Mpiks with a frequency of personnel of 25 frames per second.
There is a lot of different tasks and we always want to have the universal camera "for all tasks".
Use of a chamber with the resolution of 3.1 Mpiks and with a frequency of personnel of 12 fps will be the optimal solution. Resolution of the camera can be reduced for more high-speed work without loss of quality of the image.
The exact color rendition is important advantage of this chamber for account 24 of bit depth of color. At interpretation of result of specific coloring the exact photo of a preparation will play a key role directed by the diagnosis.
Also on the basis of this chamber the complex for the analysis of Videozavr Sperm sperm works. This chamber successfully removes mobility and morphology of spermatozoa in a native preparation, allowing to carry out the analysis to any convenient irrespective of sample life time.
