The Atik 4000LE is a reduced-cost version of our popular Atik 4000 camera.
It features the same sensor and electronics as the Atik 4000, but cooling is provided by a single-stage Peltier element, there is no water-cooling option, and fewer accessories are included.
If you want the imaging power of the Atik 4000, but don't need these extra features, then this is the camera for you.
Common features of the Atik 4000LE and Atik 11000
The other cameras in the Atik range use Sony sensors, but the large-format cameras incorporate Kodak devices. These have gained a great reputation in astrophotography, and offer qualities not available in the Sony CCDs. However, optimum performance from the Kodak chip is only obtained with the use of highly sophisticated control electronics and advanced cooling systems, and this is where Atik's design and build expertise comes to the fore.
The Kodak sensors require dark frames to be used for calibration, and these must be taken at the same temperature as the primary image. The Atik 4000LE achieves this through the provision of full set-point temperature regulation using a single-stage Peltier element and fan. This can provide cooling to 33 degrees below ambient.
Such efficient cooling cuts thermal noise to an absolute minimum and reduces the prevalence of hot pixels, but it raises the risk of condensation forming in - or on - the camera. A high-efficiency desiccant is used to dry the air inside the sensor chamber, so preventing internal condensation. Meanwhile, condensation on the outside of the camera is avoided through the use of heater elements which gently warm the window. The power supplied to this heater is controllable through software so that it can be adapted to the environmental conditions.
The Atik large-format cameras have been designed and built to meet the needs of the most demanding users, yet offer an unparalleled simplicity of use. They have only two sockets - a 2.1mm socket for the 12V power supply, and a USB2 port for communicating with your computer. The cameras are also compatible with our highly acclaimed Capture software, as well as with Astroart, CCDSoft and Maxim DL.
The Atik 4000LE is fitted with a KAI 04022 sensor as standard. This comes in a single commercial grade and is specified as having no column defects.
