The Aluma 694 is a high sensitivity research-grade Interline CCD camera using the popular Sony ICX-694ALG imaging sensor for high-quality results. It can boast several features that are unique among research-grade CCD cameras; it includes two-stage cooling, USB 2.0 and WiFi 802.11 b/g/n interfaces, ultra-reliable even-illumination shutter, and fast low-noise readout. The Aluma 694 can be operated remotely through Wi-Fi using a tablet, smartphone, or any kind of personal computer. It is compatible with Windows, Mac, and Linux operating systems.
The mechanical shutter in use with the Aluma 694 has a minimum exposure time of 0.001 seconds, and a staggering maximum exposure time of 49 days, meaning that in most practical sessions it can go for as long as you would ever feasibly need. The inbuilt cooling system is a powerful TE system using two-stage cooling in the form of a pair of variable speed fans and a high-efficiency heat sink. The maximum cooling delta of this temperature control system is -50 Celsius below the surrounding temperature.
