Intensified High Speed Camera: Ultracam3

Intensified High-Speed (>1000 fps) Camera

The Ultracam3 is a very high sensitivity high speed camera capable of acquiring images at 1000 fps at light levels as low as 2.0 x 10^-7 fc. Exposure times as low as 50ns can be achieved. The Ultracam3 contains a standard memory capable of recording 2000 images for 2 seconds (optional upgrade allows up to 8 seconds) of continuous recording at 1,000 fps with full frame resolution.

The camera can be used for special imaging of rapid events where only low ambient light is available. Multiple exposures per frame can be achieved through external control. Utilizing the ability to achieve short exposure times the camera can achieve a dynamic range of over 5 million.

The Ultracam3 contains a high quantum efficiency GEN III Image Intensifier with broadband response from 450 to 900nm at an average quantum efficiency (QE) of 35 to 40% with higher QE available on special request. This high performance intensifier is backed up by a booster intensifier. This combination is fiber optically coupled to a high sensitivity 1152 x 896 CMOS sensor. This sensor is capable of high resolution and attaining 1000 fps. Higher frame rates are also achievable. UV response from 200nm is available as an option. The camera is controlled by computer via a Gigabit Ethernet and a RS-232 connection. The camera comes complete with all the software, cables and power supply required for operation.
