High sensitivity and low noise
The newly developed 16.25-megapixel monochrome CMOS sensor for the monochrome digital camera for microscopes offers 36.0 x 23.9 mm image size. The S/N ratio is five times better than that of conventional models, with quantum efficiency up to 77% and 2.2-electron readout noise. In addition, Peltier cooling (electronic cooling) reduces dark-current noise and produces clear images with reduced noise even with dark fluorescent specimens.

  1. Conversion efficiency from light to electrical signals.
  2. Noise caused by heat from the sensor during lengthy exposures.

Superior quantitative performance
Low ± 1% linearity error of output power to input light intensity enables correct measurement of changes in brightness of specimens.

High-speed live-image display
Thanks to the USB3.0 computer connection and CMOS sensor, which provides high-speed data readout, the frame rate has been significantly improved to 45 fps (1636 x 1088 pixels), from 19 fps (1280 x 1024 pixels) with conventional models. This enables fast live-image display and easy observation point selection and focusing.
