The new Zeiss DMC 26 follows the tradition of the DMC 25 of using latest technology to ensure as exact measurements as possible and still offering a maximum of operating convenience. The DMC 26 is a computer‐controlled double‐beam reflectance photometer with the computer not only being used for data evaluation and presentation but also for controlling and checking the photometer functions. The high performance of the DMC 26 is based on the programmed interaction between photometer, computer and output units state the manufacturer. For example, the computer controls the stepping motor which sets the measuring wavelength at the double monochromator accurately to within 0.1 nm. The spectral working range for standardised colour measurement is 380 nm to 740 nm. In this range straylight always remains below 0.1%. A switch on the monochromator permits a band width of 10, 5 or 1 nm to be selected. The basic instrument is also capable of performing measurements beyond the limits of the above range without difficulty it is claimed.
