High-definition 1920 x 1200-pixel live images can be displayed at 60 fps, enabling clear observation and real-time focusing with no image deterioration. In inspection applications, the DP74 camera renders clear images of microstructures, such as fine patterns on wafers or the surfaces of new materials. When using features such as multiple image alignment (MIA) to acquire panoramic images or extended focus imaging (EFI) to capture an all-in-focus image over multiple Z-levels, the camera’s high frame rate enables users to complete their imaging tasks quickly and efficiently.

Sample appearance can vary depending on quality of material, surface conditions, or illumination methods. One of a variety of observation methods made possible by the advanced digital technology of DP74, the Live HDR (High Dynamic Range) function, combines several images taken at different exposures to accurately correct brightness differences on the sample surface on-the-fly operation, delivering a more consistently accurate sample rendition. Live HDR provides high-fidelity images that show not only textures but also flaws and defects that were previously undetectable. Glare can also be reduced for more comfortable observation.

With the position navigator, users always know where in a sample they’re making their observations. The position navigator automatically creates a map in a separate window, so users can keep track of their observation position, even without a motorized or coded stage. The map is continually updated as you move through the sample, even after changing magnification. An image of the map can be saved along with the observation image, helping eliminate the time and effort required to locate a previously imaged location in a sample.

The 3-CMOS mode is a function that we’ve adapted our popular 3-CCD mode for use with the DP74 camera’s CMOS sensor. A 2.3-megapixel CMOS is combined with pixel-shifting technology, resulting in a 20.7-megapixel resolution. In addition to conventional 3 x 3 pixel shifting of one color per pixel, the DP74 camera’s 3-CMOS pixel shift mode enables three-color image resolution (RGB) within a single pixel to further enhance resolution.
