CCD Camera

PlaneWave is an authorized dealer for Finger Lake Instruments Cameras and can provide all the most popular cameras including the ProLine Series.

ProLine sets the standards in key performance areas that include: Download Speeds, Cooling, Low Noise Operation, Anti-Ghosting Technology, Image Quality, and Linearity. ProLine download speeds are fast while maintaining low-noise frame quality. ProLine achieves outstanding cooling without water assist. Simply set the ProLine cooling where you want it and the camera will do the rest – quickly and without worries. ProLine frame quality is second to none thanks to careful design, implementation and setup. All cameras are assembled in our clean room under exacting conditions and must pass a battery of tests before being shipped.
