Product Introduction

In the field of ultrafast experiments, including explosions, high-speed impacts, plasma, laser matter interactions, and combustion diagnostics, framing cameras have gradually become the core imaging equipment. However, traditional framing cameras mainly rely on ICCD chip detectors and traditional image intensifiers, which results in slow frame rates, low dynamic ranges, and low quantum efficiency. More restrictive is that traditional dual frame continuous shooting technology, although relying on a single camera, has a fixed interval time between hundreds of nanoseconds to a few microseconds, which undoubtedly poses significant challenges to the flexibility of experiments and imaging effects.

At the beginning of 2022, Zhongzhi Science and Technology successfully developed the country's first commercialized per light MF framing camera. This camera introduces a reflective aperture splitting design and combines high quantum efficiency and low-noise Hi QE and GaAs image enhancement technologies. It can independently control the interval time of each channel, with a minimum interval time of 10ps, and can be continuously adjusted. In addition, its optical gate width has been optimized to 3 nanoseconds, which can support up to 8 channels of true framing imaging. This makes the per beam MF framing camera not only the preferred device in key experiments such as explosions, high-speed impacts, plasma and combustion diagnostics, but also demonstrates excellent temporal and spatial resolution.

　Features and advantages

●2/4/8 channel true framing imaging:

1. True 2/4/8 ICMOS cameras participate in framing imaging, which is different from traveling wave gating framing technology. 2/4/8 independent channels can participate in full frame imaging and obtain higher resolution images;

2. The exposure time of each channel can be individually and continuously adjusted, with a shutter exposure time as short as 3ns;

3. The delay between each channel is continuously adjustable from 0 to 10 seconds, with a delay resolution of up to 10 ps. Unlike dual exposure framing technology, the time interval between each frame is more flexible.

　　500ps optical shutter:

Capturing transient phenomena with picosecond accuracy and significantly reducing background noise, the imaging time resolution of plasma, explosion, and other imaging has been improved to 500ps, which can present transient process details more finely.

●Advanced Hi QE and GaAs photocathodes:

1. The latest technologies Hi Chi UV, Hi QE Blue, Hi QE Green photocathodes have a peak quantum efficiency of up to 30% and a dark count of only 50cps/cm2;

2. Ultra wide spectral response HotS20 photocathode, spectral range: 200-900nm, peak quantum efficiency up to 16%;

3. The third-generation GaAs photocathode has a peak quantum efficiency of up to 35% in the spectral range of 600-750nm.

　　●Aperture Spectral Structure:

Compared to the traditional prism beam splitting system's transmissive beam splitting path, the aperture beam splitting system adopts a total reflection beam splitting path, which can extend the spectral response to the ultraviolet band and make it easier to obtain a flat reflection spectrum across the entire band;

2. The signals of each frame in the aperture splitting system are all reflected signals, which completely solves the problem of inconsistent intensity of the transmitted and reflected signals caused by the prism splitting optical system. The intensity consistency of each frame is better;

3. The aperture splitting system adopts a reflective splitting path, completely avoiding the "ghost image" formed by the front and back of the prism in the prism splitting path;

Compared to prism splitting systems, aperture splitting systems can achieve higher optical reflectivity, thereby achieving higher signal acquisition efficiency;

5. The aperture splitting system adopts polyhedral pyramid reflection splitting, which is more compact and lightweight compared to prism splitting systems.

　　Optical imaging position alignment with pixel level accuracy between channels:

Control the consistency of the optical imaging position and pixel position differences of each channel by several pixels, and adjust the resolution to be better than 25lp/mm.

　　● Consistent gain uniformity between channels:

Perform gain testing on each frame, generate an intensity gain curve, ensure consistent intensity of each frame at the same gain through data fitting and compensation, and write the compensation file into the camera configuration. This ensures that the intensity of each frame is consistent when the camera is working and the same gain value is set.

　　●Powerful and easy-to-use SmartCapture operating software:

1. Supports multi view mode, allowing for easy switching between images, curves, single frame images, and 3D views;

　　5.Multiple measurement modes; Real time mode, single frame mode (image/curve), accumulation mode, sequence mode, sequence accumulation mode, sequence curve mode;

　　6.Automatically save, after configuration, automatically save the collected images to the specified location;

　　7.Online data processing functions, including image rotation, flipping, addition, subtraction, multiplication, division, filtering, etc;
