The image sensor of ARTIXSCAN series scanner adopts 8000-point CCD with high signal to noise ratio, and its performance is excellent. The optical resolution of ARTIXSCAN 1010 is 1000DPI×2000DPI, and the optical resolution of ARTIXSCAN 2020 is 2000DPI×2000DPI. The color depth is 36 bits. Whether it is scanning 35MM film or A4 format reflections, it can capture dynamic colors with density up to 3.4D (1010) or 3.2D (2020), and more importantly it adopts the latest patented technology of MICROTEK EDIT and is equipped with Scan color separation software COLORQUARTET which can obtain the scanning quality of the fulcrum scanner.
First, using the latest technology ARTIXSCAN series scanners use MICROTEK patented direct optical image technology (EDIT - Emulsion Direct Imaging Technology), which uses a dual light source, dual-platform patented technology. When scanning transparencies, the light source shines directly on the film, replacing the traditional scanner plus the transmission adapter method, so that the scanning light path does not need to pass through two layers of glass, so that the CCD light sensing unit can directly read the film information and thus reach high Quality, fuller, more accurate color values.
1, dual light source system (1) ARTIXSCAN 1010 dual light source system ARTIXSCAN 1010 scanner escape and unique system design, the reflection light source uses two cold cathode lamps, transmission light source uses a cold cathode lamp. The reflective light path and the transmitted light path are organically combined by five mirrors and one transmission mirror.
The optical path of the ARTIXSCAN 1010 scanner when scanning reflections is shown in Figure 1.
When scanning a reflection document, the scanning document is placed on the glass surface, and the rotating mirror is positioned at a position so that the reflected light path is not blocked by it. When the light emitted by the light source shines through the glass, the light is reflected and then reflected by four mirrors (shown by dotted lines) successively, and then the light is focused on the CCD through the transmission mirror. The light source uses two cold-cathode lamps to make the light source shine stronger, the scanned image quality is better, the image is clearer, saturated, and the levels are more abundant.
When the ARTIXSCAN 1010 scanner scans the transparency, the transparency is placed in a film holder. The film holder is placed on the underside of the scanner glass and the rotating mirror is rotated to a position above it so that light passes through it. When the light is directly irradiated on the original, the original is transmitted through the four mirrors (shown by broken lines) after being transmitted through the original, and then the light is focused on the CCD through the transmission mirror. Since there is no glass between the original and the prism, the loss of distortion of the optical path is reduced and no Newton ring is generated, so the scanned image quality can be comparable to a transparence scanner.
The optical path of the ARTIXSCAN 1010 scanner when scanning the transmitted document is shown in Figure 2.
(2) ARTIXSCAN 2020 dual-lens, dual light source system ARTIXSCAN 2020 uses dual-lens scanning module design and patented rotating lens group technology. According to the scanning transmission or reflection draft and the setting of resolution, the group of lenses is rotated on demand by the reflection, so that the beam forms different paths, and the same scanning group completes the setting of the multiple scanning mode. The rotary twin-lens design fundamentally solves the problem of edge distortion that occurs when a conventional zoom lens scans.
When the optical resolution is 666 DPI, the light valve blocks the 2000 DPI transmission lens and selects the 666 DPI transmission lens. Place the rotating mirrors 5 and 9 in the horizontal direction, and rotate the rotating mirror 4 by a certain angle or level according to whether the original is reflective or translucent....
When scanning the reflection draft, the optical path is shown in Figure 3. The light emitted by the light source passes through the glass and shines on the reflector. The light is reflected by the mirrors 1, 2, 3 and 4 (shown in dashed lines) and the transmission mirror (666 DPI) and then focused on the CCD by the reflector (from the transmission mirror. The top view of the light path to the CCD is shown in Figure 5.)
When scanning the transmitted document, the optical path is shown in Figure 4. The transmitted document is placed on the glass holder of the scanner and the light source is directly illuminated on the document. At this time, the mirror 4 is rotated into a horizontal direction. After the light is transmitted through the document, it is transmitted through the mirrors 7, 10, 8, 6 and 666 DPI. The mirror is then focused on the CCD by a mirror (a top view of the optical path from the transmission mirror to the CCD is shown in Figure 5).
When the optical resolution is 2000 DPI, the light valve blocks the lens of the 666 DPI transmission mirror and selects the lens of the 2000 DPI transmission lens. The rotating mirrors 5 and 9 are rotated by a certain angle, and the rotating mirror 4 is rotated by a certain angle or horizontally according to whether the original is a reflection document or a translucent document, and the optical path at this time is as shown in FIGS. 6 and 7 .
When scanning the reflection draft, the optical path is shown in Figure 6. When the light emitted by the light source passes through the glass and shines on the reflector, the light is reflected by the mirrors 5, 3, and 4 (shown by dotted lines) and the 2000DPI transmission mirror, and then focused on the CCD through the reflector (from the transmission mirror to The top view of the CCD's light path is shown in Figure 8.)
When looking for a transmissive document, the optical path is shown in Figure 7. Place the transmitted document on the glass holder of the scanner. The light source sweeps directly onto the original and rotates the mirror 4 into a horizontal direction. After the light is transmitted through the original, it passes through the mirrors 9, 8, 6 and the 2000DPI transmission mirror, and then The mirror is focused on the CCD (a top view of the optical path from the transmission mirror to the CCD is shown in Figure 8).
Because the ARTIX SCAN 2020 scanner does not have glass between the original and the prism, the loss of distortion of the optical path is reduced, so the quality of the scanned image can be comparable to that of a transparencies scanner. (To be continued)
The ARTIXSCAN 1010 and 2020 scanners are two platform scanners launched by ARTIXSCAN, a US subsidiary of MICROTEK in the United States, for professional users of graphic design, magazines, and small and medium-sized platemaking centers in 1998. After nearly two years of practice, they prove: Not only the scanner's performance is excellent, but also the scanned image quality is superior, especially the ARTIXSCAN 2020 scanner. With the advantages of dual-platform, dual-lens, large-size, high-resolution, etc., it becomes the only one in the market that can achieve the "four-machine integration." Functional image processing equipment, its high-quality scanning can be compared with the traditional drum scanner.
