DuncanTech Camera Technologies Crystal Clear Optics Acquisition of crisp, high quality images requires careful optical design. DuncanTech's patented compensating optics enable our 3-CCD cameras to operate over a broad spectral range while minimizing chromatic and spherical aberrations.
Special features eliminate stray light and deliver excellent color quality.
Lenses designed for use with 35 mm SLR cameras are frequently used on industrial and scientific cameras because of the high quality optics, low cost, and large image area. These lenses work very well on 1-CCD cameras. They were never designed for use with a color separating prism. The presence of a color separating prism introduces aberrations that degrade the image quality, particularly near the edges of the image, unless something is done to counteract the aberrations. To evaluate the effect a color separating prism has on image quality, an SLR lens is modeled as an ideal lens and the color separating prism is modeled by a section of glass identical in thickness to the prism.
