Apogee Aspen | CCD Camera for Astronomy

Apogee Aspen Series

Apogee Aspen is the newest design innovation in the Apogee CCD range, ideal for demanding physical science and astronomy usage. Apogee Aspen increases cooling performance, improves stray light baffling, adds a network interface with a built-in web server, and sets a new standard in shutter longevity. The Aspen’s cooling performance down to 60 °C below ambient offers low darkcurrent contribution, ensuring optimal signal to noise for long exposure applications such as astronomy.

  • Programmable cooling down to 60 °C below ambient
  • USB 2.0 and Ethernet interface
  • Range of sensors up to 16.8 Megapixel
  • 16-Bit digitization
  • High longevity shutter (> 5 million cycles)
  • Subarray readout

Product Overview

Ideally suited to challenging astronomy and physical science imaging applications, the Apogee Aspen family offers a range of popular full frame and interline CCD sensors, within a camera platform that is designed to push performance. Thermoelectric cooling down to 60 0C below ambient ensures optimal sensitivity for long exposure applications. The simple convenience of a USB 2.0 interface is accompanied by an Ethernet network interface with a built-in web server. The Apogee Aspen also utilizes a new extremely high reliability shutter, specified for > 5 million shutter cycles.

Apogee Aspen cameras are available with a wide variety of sensors, including: Back-illuminated sensors with very high quantum efficiency, some with sensitivity in the deep UV; Front-illuminated CCDs with high sensitivity in the near-IR without etaloning and a range of resolution options up to 16.8 Megapixel (CG16M model).

Sensor Options

The Apogee Aspen camera series are available with a wide variety of CCD sensors for diverse applications: from 1024 x 1024 format to high resolution 16.8 megapixel format and both front and back-illuminated full frame CCDs. Here we show the relative sizes of the sensor range available.

Full Frame CCDs

Quantum Efficiency

Back-illuminated CCDs are typically used for very low light applications due to their high quantum efficiency (QE). The UV enhanced versions of the back-illuminated CCDs have the highest QE in the UV. Back-illuminated CCDs have the highest QE in the near-IR, but are subject to etaloning in this wavelength regime (fringing caused by internal reflections). Kodak micro-lensed Blue Plus CCDs (ME suffix on the sensor part number) also have high peak QE, but much less overall QE than the back-illuminated CCDs.
