SkyRaider DS10cTEC
is Here
Introducing the new MallinCam DS10cTEC - designed from the ground up to accommodate the most demanding astronomical video imaging
applications. Since most CMOS sensors cannot be directly cooled via a cold fi nger without causing damage and delamination with time, which will
ultimately shorten their life, a new cooling system had to be developed. MallinCam developed a unique cooling system that provides no direct physical
contact between the Peltier cooler and the sensor. Instead, the Peltier cooler creates a convection system (refrigerator-like) environment that cools the
sensor without actually contacting it. This cooling system is unique to MallinCam and not found on other astronomical imaging cameras.
Since the back illuminated IMX294 class 1 CMOS sensor of the MallinCam DS10cTEC is cooled via convection, thermal shock to it and its associated
circuitry is reduced. CMOS sensors have other components mounted on the same wafer with the imaging section which do not require or can be adversely
affected by cooling. This includes the digital logic circuitry (interface, timing, processing, output amplifi ers, pad rings and associated oscillators), clocks
and timing controls, analog signal processing, analog-to-digital converter (which when under cooling from direct cold fi nger and Peltier results in
instability). These parts of the CMOS sensor do not need to be direct cooled from a cold fi nger application.
MallinCam has successfully designed a working alternative - a cooling chamber called refrigeration cooling - which subjects the CMOS sensor to
cooling inside a triple-sealed vacuumed sensor chamber controlled with a heating element mounted around the internal optical window to control and
avoid dew formation on the optical window and surroundings. A vacuumed sealed chamber is used to eliminate the use of desiccant material and keep a
dew-free environment permanently.
The result of this new technology, the SkyRaider DS10cTEC, will not require a dark frame for live application or imaging in most cases. It is built to
laboratory specifi cation, where CNC machining is used throughout to provide the rigid tolerances needed to provide precise component matching. The
chamber has six stainless steel screws securing the chamber cover under 100 pounds of pressure to avoid possible air leaks into the chamber.
The internal electronics use Grade 1 components with tolerance of 0.5%, a military and aerospace standard. The camera contains 4Gb DDR3 internal
memory to insure the smooth fl ow of data to the computer. The DS10cTEC also has a built-in USB2 hub that can support a guider or a USB type focuser.
Each camera is subjected to a 24-hour burn-in prior to being ready for shipment to insure proper operation. It is these details that set MallinCam
apart from everyone else.
