Ultimate Sensitivity Back-illuminated sCMOS for Astronomy & Physical Sciences
Marana- Space debris & NEO – track smaller objects
- Detect smaller occultations
- Lower laser powers – preserve photosensitive samples
- Shorter exposures – follow fast events, e.g. pulsars and fast reactions
- Lower detection limits / trace concentrations
- Higher dynamic range photometry
- AO wavefront sensing on weaker signals
- Extremely narrowband filters (e.g. Solar)
- Fluorescence down to single ultra-cold atoms
Marana 4.2B-11: Superior Field of View

Application Focus

Solar System Objects A Near-Earth Object (NEO) is any small SolarSystem body whose orbit brings it into proximity with Earth. Over 20,000 known Near Earth Asteroids have been discovered, of which almost 1000 are larger than 1 km. The inventory is much less complete for smaller objects, which still have potential for large scale damage. While asteroids are constantly being eliminated from our solar system, unfortunately new ones are pulled into orbit. Thus, NEO surveys are required as an ongoing discipline in astronomy. The large field of view, very high sensitivity and fast readout of Marana 4.2B-11 is ideal for enhancing statistics of object detection, either directly visualised or byoccultation. |

 Marana 4.2B-6 Purchase Flexibility
Don't want to commit to CoaXPress connectivity from the outset? If preferred, order the less expensive USB 3.0-only version and later avail of a simple in-field upgrade to CoaXPress capability, using the CHAM-UPG-CXP code, if and when additional speed is needed. The upgrade includes CoaXPress card, cable and remote session to upgrade camera firmware and unlock
CoaXPress capability. Please contact your sales representative for more information.

Ultimate sCMOS Sensitivity
The Marana models contain a back-illuminated sCMOS sensor with up to 95% QE, complemented by market-leading vacuum cooling of the sensor for lowest noise floor. The Marana 4.2B-11 model features larger 11 µm pixels, optimal for maximum photon capture in light starved applications.
Comparative Signal to Noise under low light conditions (10 incident photons per 100 µm2 sensor area) - Under identical low light optical conditions, the Marana 4.2B-11 with back-illumination and large pixel size is well suited to maximizing photon capture and Signal to Noise.
sCMOS Solutions for Extended Dynamic Range
Andor sCMOS cameras each offer an Extended Dynamic Range functionality, supported by a 16-bit data range. Harnessing an innovative ‘multi-amplifier’ sensor architecture, we can access the maximum pixel well depth AND the lowest noise simultaneously, ensuring that we can quantify extremely weak and relatively bright signal regions in one snap. In the physical sciences, high dynamic range capability is central to countless measurement types, such as in astronomical photometry.
Measurements taken of a high dynamic range test chart using Marana 4.2B-11 in Extended Dynamic Range Mode, which enables accurate quantification of signal intensities that range from the noise floor detection limit to the full pixel well depth.
Furthermore, to achieve best in class quantification accuracy, Andor have implemented enhanced on-head intelligence to deliver market-leading linearity of > 99.7%.
