高速像增强相机模块 HiCATT
- HiCATT
新闻
更多HiCATT是一款用于同高速相机共同工作使用的像增强模块。该模块可以实现弱信号放大到10000倍以上,提高高速相机的灵敏度,从而实现高速的弱光成像。HiCATT有高质量的镜头耦合装置,适合市面上主流高速相机接口。
Hi CATT的像增强器是混合的,含有两级,直径可以是25mm或18mm。前一级是二代或是三代管的MCP像增强器,可以提供很高且可调的增益。第二级是一个一代管的增强器(booster),可以在高帧率的情况下增强成像强度。在门控模式下,第一级可以作为纳秒两级的光电开关。像增强器的工作频率在Burst模式下可以到2.5MHz
关键优势:
- 方便耦合市场上主流高速相机(最快到300,000fps)
- 高分辨像增强器:提供二代或三代像增强器,可覆盖从紫外、可见到近红波段。
- 极小门宽:最小可达3ns(FWHM)
- 接受高速重复频率,最快可达300KHz/2.5MHz burst
- 紧凑型设计
- 过曝保护:用户可自定义阳极电流上限
应用:
- 激光诱导荧光(LIF)
- 粒子图像测速(PIV)
- 燃烧实验
- 单光子成像
- 生物、化学发光成像
- 等离子体物理
- 天文
- 时间分辨成像和光谱
