流式细胞术是一种分析在流通池中以平移运动快速循环的细胞的性质和结构的技术,可通过以激光光束辐照细胞并观测其散射光和荧光进行测量。用于流式细胞术的设备称为流式细胞仪。
PD 用于测量散射光,而 PMT、APD 或 MPPC 则用于测量荧光。高速 CCD 相机或类似设备用于成像流式细胞仪,它结合了显微镜和流式细胞仪的功能。
H14121 系列光电传感器模块包含一个金属封装 PMT(具有 GaAsP/GaAs 光阴极面)和一个高压电源电路。H14121-40(GaAsP 光阴极面)在 300 nm 至 740 nm 波长的光谱范围内具有高灵敏度。H14121-50(GaAs 光阴极面)在 380 nm 至 900 nm 的宽光谱范围内具有灵敏度。
该产品阵容包括三种类型的输出通道:4 通道、6 通道、8 通道,可根据用途进行选择。还可根据需要安装定制滤波器和二向色镜。请随时联系我们,提出您的需求。
APD 模块是具有内置硅 APD 的高灵敏度、高速响应光探测模块。此类模块集成了硅 APD、I/V 转换器和电源,因而使用非常方便。
APD 适用于使用其称为雪崩倍增的内部倍增功能(约数百倍)进行的高灵敏度、高速信号测量。
不同类型的 APD 模块具有不同的光谱响应范围和频带。也可应要求提供定制模块。
MPPC 模块是带有内置 MPPC 的光子计数模块。此类模块集成了 MPPC、I/V 转换器和电源,因而使用非常方便。
MPPC 具有高增益(约 106)、高光子探测效率、宽动态范围和出色的光子峰值鉴别能力,因此即使在高速、弱信号下也能获得高信噪比特性。
提供两种具有不同光谱响应范围的波长类型。此外,还有一种易于进行光学调节的类型,此类设备还配备适用于狭窄位置的柔性电缆。也可应要求提供定制模块。
- C13365 系列:短波长类型
- C13367 系列:短波长类型(带柔性电缆)
- C14452 系列:近红外类型
我们提供各种选择,包括定制产品。
这些相机包含一个 TDI(时间延迟积分)传感器。
