Why choose a line scan camera with 20 µm x 20 µm pixels?– Here are 6 good reasons:
Reason #1:With larger pixels you can scan with less scene light:The Sweep SW-2000M can collect four times as many photons from a given scene than a camera with only 10 µm pixels, (provided that the field of view and lens aperture are the same), giving better image quality with less light intensity. This means that you can scale down the investment in expensive light solutions in your 2K line scan inspection systems.Reason #2:With larger pixels you can obtain faster scan rates:When the amount of light is limited, the Sweep camera can capture an acceptable exposure at double the line rate of a camera having only 14 µm x 14 µm pixels, and 4 times the speed of a camera with 10-micron pixels. Reason #3:With larger pixels you get better signal/noise ratios:The SW-2000M-CL has a larger pixel area to collect photons (20 µm x 20 µm = 400 µm2). This is, for example, 4 times the photo-sensitive area compared to a camera with only 10 µm pixel size. (10 µm x 10 µm = 100 µm2). The larger photon collection area is typically also associated with a larger quantum well capacity compared to a camera with smaller pixels. A large photon collection area combined with a larger quantum well capacity in Sweep, provides a better signal/noise level maximizing the image quality.
Reason #4:With larger pixels you can lower the requirements to lens quality:Because of the large pixels, the camera sets lower requirements to the “Modulation Transfer Function - MTF” performance specifications of the lens. In other words SW-2000M has a higher tolerance to “lens blur” and is less dependent on high quality lenses with high spatial resolution to obtain good image quality. Therefore you can choose a less costly lens without compromising on image quality or get even sharper images when a high quality lens is applied. Reason #5:With larger pixels it is possible to minimize the physical dimension of the vision system:A 2048-pixel camera with 20 µm pixels can be moved closer to the inspected object (keeping the same Field-of-View) than a 2048 pixel camera with only 10 µm size pixels using the same focal length lens. This means the physical dimension of the vision system can be minimized. Moving closer to the objects being scanned also means that less scene light is needed. This means that the inspection systems can be designed with less advanced light thereby lowering the illumination costs.Reason #6:With Sweep SP-2000M you get an exceptionally good price/performance ratio:Besides the above advantages, SW-2000M has a good price/performance ratio, so you can stretch your camera budget further, getting more cameras for the same investment. This will further improve the competitive edge of your line scan inspection system.Applications: The Sweep 2000M line scan camera offers a new competitive camera component to system integrators and OEM companies developing line scan inspection systems to be used in the following areas:
