Mention a microscopic imaging camera top, we will think of first is Olympus, Leica, Zeiss, Nikon, four microscope family 12 megapixel high-definition camera. In order to balance between high pixel and fast preview, the four top of the family of the top of the same 1400000 pixel camera with the use of micro displacement and image mosaic technology. 1.4 million pixels, to ensure the preview time of high-speed and micro displacement and image stitching and compensate for the millions of pixels only when defects of microscopic details of the shooting, so as to achieve the microscope to take a peak.
But the high price and the need of displacement mosaic speed has been affecting the perfect use of the camera. With the continuous progress of semiconductor production technology, Tucson the China's own microscope camera company also began to expose the brilliance in the field. From the beginning we know the low-end CMOS camera to 140 million pixel CCD camera, to microscope developed 330 million camera. Today eight million camera Tucsen and placed in the our evaluation platform.
According to Tucson engineers, Tucson in entering the field of microscope imaging, listen to the views of various agents, and with the German and American professional microscope with in-depth exchanges, from hardware to software do the various aspects of the update. On the understanding that the microscope is, high-speed preview (convenient we use when focusing), high definition of filming, specially developed this section for bright field microscopy with high resolution camera, and due to his actual pixel for 800 million pixels, rather than the micro displacement technology, fine degree higher.
Product features: 8000000 high pixel, high precision
Professional CCD camera, color more natural
High frame rate 18fps, more rapid focusing
Recommended by the manufacturer: high resolution, high definition and clear field microscope
The camera manufacturer can provide a standard adapter for the full platform microscope, since the chip size is 1/1.8 inch, so it is recommended that the 0.5X adapter. The camera is an all aluminum housing, the manufacturer's promotional page provides a red and blue two kinds of shell, provided in our hands is a red shell of the camera.
The interface part of the camera is the standard C interface, so the same as the C interface adapter can also be used in the factory of the various microscopes. Camera supporting the CD of a Tucson, compared to many domestic manufacturers of the microscope camera supporting CD-ROM undoubtedly Tucson spent a lot of effort, black bottom disc, among many microscope photograph picture, from the author's point of view, and is similar to the camera by equally obvious micro photo gallery of photos is not as great, and should be taken by their own, the breath of professional pavement and.
8000000 camera parameter details
Chip size: 1/1.8 inch
Interface: Standard C interface
The maximum frame rate: 18 frames (640X480) resolution
A/D bit depth: 12bit
USB length 2.5 meters
The biggest highlight of the camera from the parameters of the camera is the resolution of the 3280X2460, and the other is the resolution of 640 x 480 18fps high-speed preview. As we all know, in general, the preview speed of 25 frames, eyes will be rapid transformation of the screen as a continuous picture, there will not be a pause. So the faster frame rate to us for the more favorable focusing microscope.
It is also for this consideration four manufacturers have used the micro displacement microscope technology to achieve high pixel. But that is the use of micro displacement technology, they are how the frame rate:
OLYMPUS 15fps DP72
Leica DFC500 did not provide
AxioCam HR 12fps Zeiss
R1i: 19fps Nikon
Thus Tucsen to 18fps's high preview speed than OLYMPUS and Zeiss, ranked second.
From the practical perspective, the camera focusing time sensitive reaction, basically do not feel tailing, broke through the high pixel camera tail sense.
Installation details and evaluation of 800W camera
We used the microscope to be Primo Star Zeiss Ming field microscope, with the original 0.63X digital pick tube. It should be said that the installation process is very simple, the first connecting tube connected directly to the camera lens and microscope.
Computer: open the CD after the corresponding drive and Tucsen microscope software TSView. sequentially installed, it is worth mentioning is Tucsen provided by the driving is an EXE file, after installing vista system, we directly in camera, camera automatically recognized directly can use, completely eliminating the need for positioning themselves to trouble the driver files, simple and convenient.
But when installed on the computer appears a small episode, I began the microscope connected to the top of a USB hub driver installation completely normal, but the open supporting TSView software shows can not find the hardware. After consulting our engineer, originally they consider to USB hub often do not good shielding and anti-interference ability, the image quality, specially in the software to do the such considerations, prevent users in the hub of unqualified influence on images. However, as end users are used here, as we tend to feel the need to solve the problem of the problem, we suggest that the tsview software on the corresponding tips.
After changing to the computer on the USB interface, the use of normal, we have to start testing.
Evaluation platform and method:
Taking into account that we are mainly taking pictures of the Ming and the manufacturers recommended, so we use a bright field microscope. Be considered now occasionally take fluorescence images, we will put microscope lights off and adjusted to the minimum light (primo star is led can be adjusted to very dark), to see whether there is a possible fluorescence of shooting.
Microscope: Star 0.63X, Primo digital tube
From the screenshot above can see Tsview shooting of the function is good, the interval for a period of time for automatic shooting, video recording function, after the shooting pictures directly displayed in the lower right corner, very convenient.
From the set up, you can set options more from color, white balance, camera out of the style, more options to take pictures of the ideal picture. By setting the color, we took photos of different colors, is actual shooting look accurate color reproduction, the discrimination is good and enhanced color options, can also be a photograph of a variety of effects. At the same time, we also found that the CCD camera is more than the CMOS camera to get more color details.
Detail effect test:
Attached: Tucsen800 megapixel camera CCD details, myocardial cell cross striations clearly visible.
Color effect test:
Attached: the low price of the CMOS camera and Tucsen800 million pixel CCD camera color contrast, CCD can get more color information.
Dark field photography test:
But we were shooting dark photos of the basic test failed, the camera with the longest exposure time more than 500 ms, less than a second, and from a practical point of view because of the high pixel, the sensitivity of the chip is not high, the same exposure time, the brightness of the photo far as Zeiss AxioCam hr.
So as Tucsen recommended this is a suitable for bright field, phase contrast, high resolution camera and metallographic field. Can shoot the visible light.
Other real shot pictures:
From the first three million pixel CCD microscope camera, to now 8 million pixel CCD microscope camera. Tucsen microscope industry to create the most suitable microscope camera not with spare capacity, from which we can see their way over to, in three years time, hardware in the CCD launched the 1.4m. 3 million, 6 million, eight million four types, the old model also for the update performance do a lot to improve. The software is upgraded many times, more and more convenient for the user to use.
In the middle we see a user oriented service mentality. Believe they can do better in the future, we can also from the price of their very high performance and civilians, break the Dachang high, taking pictures of more precise and professional.
