DISCOVERY Plus

  
We have developed the new version of DISCOVERY: the DISCOVERY Plus series!

It maintains the characteristics of the former DS series: high sensitivity, reduced weight and dimensions and low costs. Moreover it offers you a USB connection, a selectable 12, 14, 16 bit A/D converter digitization and more!

Every component is integrated in the aluminium head: CCD, electromechanical shutter, Peltier cooling system, electronics.

You can choose between the standard cooling version: Single stage Peltier reaching up 35 °C below ambient and the enhanced cooling version: Double stage Peltier reaching up 45 °C below ambient.

 

DISCOVER Plus series will offer you professional performances at cheap costs.
This series uses KAF series of CCD sensors, displaying a wide range of resolutions and pixel dimensions.
The sensors are front-illuminated, supported by an excellent quantum efficiency.

All of them (apart from those with the anti-blooming option) can offer a 100% fill factor, allowing one to shoot marvellous images!

Among the main application fields: Astronomy, Plasma Physics.
