sCMOS Cameras
The challenge of CMOS cameras has been maintaining performance when scaling to larger formats; in particular offering the combination of speed and low noise architecture.
COSMOS delivers deep-cooled, low-noise performance on a multi-megapixel scale with global shutter, 18-bit readout, and glow reduction technology.
Due to back-illumination, the COSMOS achieves near-perfect light collection, achieving over 90% peak quantum efficiency.
With minimal 0.7 e- read noise and 0.05 e-/p/s dark current, the COSMOS is able to detect the weakest of signals.
The COSMOS is well suited to dynamic imaging applications due to its fast frame rates and high sensitivity. In addition, the short readout times can enable quick decision making and analysis.
With the ability to select multiple regions of interest (or imaging apertures) the COSMOS can improve readout speed while reducing unnecessary data.
COSMOS offers an incredibly wide high dynamic range of 54,000 (94 dB) for measuring both bright and finat signal within the same image.
Alongside the high dynamic range, the proprietary analog-to-digital converter design present within COSMOS provides unsurpassed linearity across the entire dynamic range, improving quantitative precision across all measurements.
Electronic global shutter devices are often necessary for the capture of fast-moving objects. This is achieved on CMOS through the addition of a “storage area” within each pixel. However, global shutters on back-illuminated CMOS devices were not previously possible due to parasitic light artifacts.
The COSMOS has a redesigned pixel structure allowing for back-illumination alongside a global shutter. This redesign also minimizes parasitic light sensitivity, providing both the best sensitivity and artefact-free imaging.
Deep cooling is essential to reduce the thermal dark current noise generated from long exposure times. The COSMOS builds on Teledyne Imaging’s industry-leading cooling performance, achieving -30°C cooling with low dark current.
COSMOS sensors are also cooled from the moment of manufacture, providing far superior image quality, free of glows found in other back-illuminated sensors.
The integrated all-metal, hermetically sealed vacuum enclosure, with lifetime warranty, prevents any outgassing or degradation problems, common within other cameras.
PICAM API and SDKs, from Teledyne Princeton Instruments, offers complete control over all cameras. Available for all Linux and 64-bit Windows systems, PICAM allows for the ultimate flexibility, providing ease of integration for any system.
PICAM provides developers, scientists and integrators the ability to build their own control and user interface directly on top of the driver, configuring the identified hardware by adjusting parameters within its interface.
