Axiocam 702 mono Ultra Fast Camera
- Category: Microscopes, Cameras
The Axiocam 702 mono camera from ZEISS is specifically designed for high-performance imaging at low light, and more particularly for live fluorescent cell acquisition.
Its 2.3 MP CMOS sensor of 1/1.2" (diagonal 13.3 mm) can reach a frame rate of 128 fps at full resolution (1920 x 1216).
This camera embeds a Peltier cooling technology, ensuring low noise, low light sensitivity and reproducible images, especially in dark areas or for long exposures.
Highlights
- 2.3 Megapixel low image noise CMOS sensor
- 128 frames per second at full resolution (1920 x 1216)
- Peltier cooling system for low read noise
- HDR (High Dynamic Range) mode for extended bit depth imaging
- Fast USB 3.0 connection
- Global shutter readout avoids CMOS rolling shutter image distortions
- Hardware trigger support in ZEN multidimensional acquisition
- Fast and efficient operation with ZEN Software
Fast Imaging At Low Light
Whether the task is high resolution imaging requiring sensitivity or keeping up with fast dynamic events, Axiocam 702 mono can do the job. Axiocam 702 mono uses a global shutter CMOS chip offering full frame speeds of 128 frames per second and more than 1000 frames per second with smaller frame sizes. Easy to use and learn ZEN software drives the camera with seamless integration and compatibility with multiple ZEISS stands and microscopes systems.

All frame rates are maximum values at short exposure times below readout time of the sensor. Exposure time, computer hardware operating system and software can reduce the maximum achievable frame rates. By using binning or sensor sub regions (ROI), the frame rates can be further increased. Technical data is subject to changes due to technical progress.
