RETIGA E20Small Pixel CMOS

The all-new Retiga E20 CMOS combines our smallest-ever pixel with a 20 megapixel sensor, allowing for high-resolution imaging across large samples, even at the lowest magnifications! The Retiga E20 is also capable of long-exposure imaging thanks to our major breakthroughs in thermal noise control, allowing exposures of up to an hour. This compact yet powerful CMOS is an ideal solution for both low-magnification and long-exposure imaging, capture it all with the Retiga E20! 

  • Small 2.4 μm pixel for high-resolution at low-magnification
  • 20 Megapixel sensor
  • Capable of exposure times over 60 minutes
  • Ultra low dark current <0.003 e/p/s
  • Extended Dynamic Range Mode

Key Features

Small Pixel Imaging

The Retiga E20 features our smallest-ever pixel at 2.4 μm, which results in high-resolution imaging at even the lowest magnifications. Combined with a 20-Megapixel array (5472 x 3648) the Retiga E20 can pick out even the smallest details from large samples in a high-throughput manner.

With low noise contribution and a high peak QE, the Retiga E20 will deliver high quality images of your samples even in low-light conditions.

Long Exposure Imaging

Thanks to major breakthroughs in thermal noise control, the Retiga E20 CMOS has an ultra-low dark current of 0.003 electrons per pixel per second, allowing for exposure times of up to an hour.

Stretching exposure times from seconds to minutes to hours in this manner results in comfortable detection of even the weakest signals, ideal for imaging luminescence or for astronomy.

Extended Dynamic Range

As well as Speed and Long Exposure modes, the Retiga E20 features Extended Dynamic Range (EDR) mode, which combines a large full well capacity with a low read noise to result in ~2.5x more dynamic range than other modes, easily capturing both intense and weak signals in the same image.

OEM Integration

Interfacing is simple with the Retiga E20 by design. With its compact format and single cable interface, hardware integration is straightforward. The addition of onboard triggering, Windows/Linux support, and our dedicated OEM team make integrating and customising the Retiga E20 a painless process.
