Nikon Instruments has announced the addition of the DS-Fi1 digital camera head and DS-L2 and DS-U2 control units to its Digital Sight Series of cameras. An accelerated frame rate for the DS-Fi1 makes positioning and focusing easier, and its interline CCD solid-state image sensor provides a resolution of 5.0 million pixels to produces quality brightfield, darkfield, phase contrast, DIC and fluorescence images. The Nikon DS-Fi1 incorporates an IR filter on the camera head to improve red color reproduction. Two new control units give the user a choice of a simple-to-use stand-alone system, or a hub controller for connection to a PC which facilitates more complex image analysis. Live images can be comfortably captured, observed, recorded and utilized using the stand-alone DS-L2 controller. An 8.4-inch LCD monitor can be split to display a still alongside a live image, which is useful for applications requiring the user to compare and contrast a sample image with a live image. Optimal image capture settings can be configured simply by selecting the observation method, such as brightfield or darkfield, and the type of sample. In the Biological Scene Mode there is even a mode optimized for HE and ELISA (enzyme antibodies) stained specimens for use with medical samples that require subtle color reproduction. The DS-U2 control allows every step from advanced image capture to image processing and analysis to be made through connection to a PC with NIS-Elements software. The USB 2.0 device port enables the transfer of image files to a PC at twice the speed of the previous model.
