It is the only large format scanner in the market that can output 1000ppi resolution in 96-bit color scanning mode, and it is absolutely competent for high-precision digital scanning of precious documents.
Which is better, the middle view scanner or the thinking view scanner?
I think the scanner is better. As one of the representative products of professional hand-held 3D scanner, it has quasi-industrial scanning accuracy (the highest basic accuracy is 0. 1mm, the highest stitching accuracy is 0.3mm/m) and fineness (the highest resolution is 0.2mm), and comes standard with high-definition color scanning module, which can meet the scanning needs of most medium and large items and human bodies.
Seshu series scanners are famous for their ultra-high scanning accuracy. Due to the use of mature linear CCD sensors,
Its high-precision true color scanning lens can obtain a very high degree of color reproduction and perfectly reproduce the original.
All visible details. The ancient match scanner is the best in the whole series and should meet the requirements of the topic.

Matters needing attention in purchasing 3d scanner
Accuracy: Accuracy is very important, and it is a key resolution that everyone must make for the data information of 3D scanner. This is especially true in industrial production and application, and accuracy is usually the most important factor in this industry.
In order to achieve the best accuracy, the scanner must be calibrated. All 3D scanners are calibrated by the factory, and the factory will ensure the maximum accuracy of the equipment. Some 3D scanners are also suitable for temporary calibration. In other words, consumers can manually adjust the accuracy settings of 3D scanners at any time after purchasing equipment according to their own requirements, so as to consider the optimal specifications of manufacturers.
Resolution: Although accuracy is the key factor to consider when choosing a 3D scanner, there are other factors that must also be considered, such as the resolution of scanner equipment. Accuracy is an index value considering the front accuracy of scanner equipment, and resolution is an index value considering the shortest path between two points of three-dimensional solid model, generally in mm or μ m.
This is very important for quality management, reverse engineering, animation and virtual reality technology, cultural heritage protection, forensic identification, jewelry and many other scenes. The higher the resolution, the richer the key points of the three-dimensional solid model.
What scanner has high scanning accuracy?
You can look at Zhongjing's 9900XL scanner, which has excellent scanning performance. Three-wavelength (R.G.B) white LED light source, color, gray, black and white scanning mode.

Which scanner is better?
With the price reduction of scanners, in addition to printers, scanners have gradually entered offices and homes, becoming indispensable computer peripherals for users. At present, there are many brands of scanners, but I think the really good brands should be Canon, Zhongjing, Ziguang, Epson and BenQ BenQ, all of which are the top ten scanner brands bought on the top ten brand portals. If you buy them, you can rest assured.
What brand of scanner is good?
Well-known brands prefer Epson, followed by Canon. There are also the old brands of domestic MICROSCOPE and scanners, which are themselves producing optical instruments, so the scanning quality is not lost to Japanese brands at all.
In terms of price, in fact, everything around 300 yuan is ok. Because no matter how high-end, you need high-end scanning products of more than 1,000 yuan. Generally, in low-end products, the scanners of 500~600 yuan are not much different from those of 300 yuan. The scanner of 500~600 yuan is just a little more functional, and it's all chicken ribs that you may never use. For example, scanning one copy, sending one email after another, just this boring function, and then adding unnecessary prices to you.
More importantly, the technology of scanner products has long been fully mature, and there is not much technical difference between the same grade, different prices and different brands. So there is no need to spend more money for some external factors. For a scanner, good results are king, and the rest are just clouds.
Therefore, it is more important to buy one with good effect than one with many functions.
In terms of types, it is best to buy a scanner using CCD photosensitive components. CCD scanner is thicker and slightly larger, but it must have a good scanning effect, especially a fuller color.
Now it is generally recommended that you buy a CIS or LED scanner. The only advantage of this scanner is that it is relatively small and can be made very thin. But the scanning effect is not good.
Which brand of scanner is the best?
Canon Canon (world brand, leading brand, market share first, Japan 1937)
Zhongjing (domestic scanner flag inkstone brand, top ten scanner brands)
Ziguang (1988 Beijing, national key high-tech enterprise, top ten scanner brands)
Epson Epson (Nagano, Japan, global leader in digital imaging, 1942)
BenQ BenQ( 1984 was founded in Taiwan Province province, a world brand and one of the top ten scanner brands).
HP HP( 1939 California, USA, world brand, top ten scanner brands)
Hanwang Hardware (Beijing in 1998, national high-tech enterprise, top ten scanner brands)
Which type of scanner is more suitable for home use?
There are only a few hundred small household scanners on the market now. If you want to buy a cost-effective scanner to basically meet the demand, I bought a flat-panel scanner in Zhongjing.
What is the best scanner at present?
It is recommended that Ziguang or Canon brand stay longer, and the after-sales service is guaranteed. You can find it online in Shang Ya.
Which is better for purple scanner?
The well-known scanners on the market are all Canon HP Fujitsu Hong Guang Founder, which are all good, depending on the configuration.

Hello: Do you need a scanner in A4 format or A3 format? Can you say it briefly?
What scanning element is better for scanner?
I found this for you. I hope I can help you. Not really!
At present, all HP scanners sold in China adopt CCD(ChargedCoupledDevice) technology.
Usually, when people mention the scanner, they will pay more attention to its scan resolution, but they may not care about the photosensitive elements it uses. Many users will be confused whether to choose CCD scanner or CIS scanner. Which scanner is more suitable?
Simply put, the difference between the two scanners is the photosensitive device. CCD scanners use electronic coupling devices, while CIS scanners use contact image sensing devices. The working principles of these two photosensitive devices are completely different: CCD element itself is the core of the whole scanner imaging, but the light emitted by the light source must be reflected and focused by the lens, and the addition of these optical devices increases the cost of the whole scanner; The CIS scanner uses the light emitted by a tiny light source to be reflected by the scanned manuscript and then directly received by the photosensitive device. CIS photosensitive device itself is enough to complete the imaging task, without the participation of lens and lens, so the assembly of the product is very easy and the cost is very low. Because CIS scanner relies on directly receiving reflected light for imaging, its technical content is relatively low and its scanning depth of field performance is poor. Except for the difference in the photosensitive part, the working principles of other parts of the two scanners are basically the same, and they all convert optical signals into digital information.
Comparing the two scanner products, CCD scanner has obvious advantages, but CIS scanner is not without its merits.
The disadvantage of CCD scanner is that it needs a whole set of optical system, including illumination cold light source, polygon mirror and optical lens, to image on the surface of CCD sensor through complex optical path. Its components are complex, the cost is relatively high, and the processing of scanned image data is relatively complicated. Generally, the cold cathode tube is used as the light source, and it needs to be preheated for about 1 minute to stably emit light. CCD scanner needs to image through a series of lenses and mirrors, so it will produce color difference and optical aberration, and generally it needs color correction through scanning software.
The advantage of CIS scanner is modular design, which integrates scanning light source, sensor and amplifier, and its structure, principle and optical path are extremely simple. Theoretically, the image directly obtained by the sensor from the original surface will not produce color shift and aberration, and the image effect closest to the original can be obtained. The design and manufacturing costs can be reduced, the volume of the product can be designed thinner and smaller, and the CIS scanner has no obvious waiting time.
The disadvantage of CIS scanner is that it can't use the lens, but can only scan close to the original, and the scanning accuracy is low. In addition, its light source can only use LED, which has poor color and uniformity, narrower color gamut than CCD, less rich color and shorter service life.
In addition, because the traditional CCD scanner uses an optical lens to image on the CCD plane, it has a certain depth of field, and can get a clear scanning effect on the raised spine and even the object. CIS scanning head uses sensors to acquire images from the surface of the scanned object. The depth of field is short, and the scanning level is somewhat insufficient. It seems that it is impossible to scan uneven manuscripts and pictures. The object to be scanned must be placed on the scanner smoothly. The depth of field of CCD is at least 10 times that of CIS, which means that the CCD scanner scans 3D objects clearly and vividly in a certain range, while the output image of CIS scanner tends to be blurred and defocused when scanning slightly uneven objects.
High-quality CCD photosensitive element, the same quality can be used 10000 hours. However, the brightness of the light-emitting elements of the current CIS scanner is reduced by 30% on average after 500 hours of use, which means that the life of the light-emitting elements of the CIS scanner is very short.
