COSMOS Datasheet Introducing COSMOS COSMOS is a portfolio of large area CMOS cameras, conceived and designed to deliver unprecedented performance. The COSMOS concept started with our customers, whose research and applications require camera functionality and performance that is not commercially available with either CCD or CMOS technology. Having experience in all aspects of sensor and camera design, Teledyne was well positioned to combine its resources to answer this challenge. Our CCD and CMOS sensor design teams were challenged to merge their expertise to deliver unmatched sensor...

COSMOS Datasheet Applications Exoplanets Exoplanet study is at the forefront of astronomy, with various techniques, such as transit photometry and radial velocity, used for identification and characterization. These techniques often require a camera with high precision, low noise, large dynamic range and high duty cycle to detect any small variations in the luminosity of the exoplanet’s associated star. The deep cooling and low read noise of 0.7 e-, 3x lower than our world-leading CCD sensors, empowers COSMOS to measure these slight variations. Greater than 90% peak quantum efficiency is...

COSMOS Datasheet Solar Physics The Sun is continually changing. Studying these dynamic events can provide valuable insight into the processes within a star. With high spatial and temporal resolution, the COSMOS allows for accurate investigation into the dynamic events of the solar atmosphere. The large pixel size and large pixel array of the COSMOS provides the most comprehensive field of view, allowing capture of the entire area of an event, such as a sunspot, to be imaged within one sensor.

COSMOS Datasheet Techniques Adaptive Optics Adaptive optics is a technique that provides higher resolution images by counteracting the effects of atmospheric turbulence. In order to correct for these atmospheric changes, the adaptive optics system utilizes a camera with both fast frame rates and low read noise to feed back into the telescope system to make atmospheric adjustments. With a read noise of 0.7 e-, the COSMOS is able to capture faint stars that are closer to the scientific object of interest. The COSMOS also provides fast frame rates without sacrificing sensitivity, with...

COSMOS Datasheet Speckle and Lucky Imaging Speckle and lucky imaging are two alternative methods for counteracting atmospheric turbulence, which both utilize rapid image acquisition to “freeze” turbulence motion, overall improving image resolution. These techniques both require a camera with fast readout and low noise, not only to counteract the effects of turbulence, but to also detect the object of interest with much shorter exposure times. The COSMOS is able to combine short exposure time with fast frame rates of up to 50 fps, allowing for rapid image capture to deliver...

COSMOS Datasheet Key Features Explored Unbeatable Sensitivity COSMOS achieves near-perfect light collection thanks to back-illumination, with quantum efficiency peaking at over 90%. What’s more, with minimal 0.7e- read noise and 0.05e-/p/s dark current, the COSMOS surpasses both CCD and EMCCD technology in its ability to detect weak signals. Over 90% Peak QE! And with UV and NIR sensitivity! Resolution Resolution from ground-based astronomy is often limited by atmospheric turbulence. Techniques such as lucky and speckle imaging “freeze” any turbulence through the fast acquisition of images,...

COSMOS Datasheet Fast Frame Rates With fast frame rates and high sensitivity, COSMOS is well suited to dynamic imaging applications. Further, the short readout times can enable quick decision making and analysis. Frame rate at full resolution, High Speed Mode, Rolling Shutter Resolution Frame rate at reduced resolution, Rolling Shutter Aperture / Region Size High Dynamic Range (16 bit) Multiple Regions of Interest Improve readout speed while reducing unnecessary data through selecting multiple regions of interest (imaging apertures). For example, capture a reference star in one region, and...

COSMOS Datasheet Large Sensor Size COSMOS multiple sensor size options allow researchers to tailor a camera to a specific optical system, achieving the maximum image size possible to capture larger areas than ever before. Choices include the 92 mm diagonal, 6.5k x 6.5k pixel COSMOS-42M and the ground-breaking 115mm diagonal, 8k x 8k pixel COSMOS-66M. Unmatched Dynamic Range and Linear Response High dynamic range allows for fine measurements of both very bright objects and very dim objects within the same image. Due to its low noise performance combined with 18-bit readout, COSMOS offers an...
