Hamamatsu光电倍增管模块

  • 宽光谱响应
  • 快速响应时间
  • 低暗噪声
  • 高灵敏度

光电倍增管(PMT)模块结合了一个高压电源光电倍增管,并往往结合其他信号处理电子器件。各种不同的光电倍增管模块,可提供不同的输出信号格式(电流或电压) ,光谱响应,放大器增益和带宽,以及有效面积的尺寸。 #57-559和#57-560整合了一个8毫米正向光电倍增管和一个1伏/微安 20千赫兹的低噪声放大器。 #57-561和#57-562使用15毫米正向光电倍增管和0.1伏/微安200千赫兹的放大器。 #57-563和#57-564为电流输出型光电倍增管模块,上升时间为0.78纳秒。#57-731是一种高增益(107)电流输出侧向光电倍增管模块,适合用于宽带光谱仪和其他精密分光测量设备。尽管所有的光电倍增管模块都接受直射光输入, #57-559,#57-560,#57-563 和#57-564还可通过SMA或FC适配器实现光纤耦合。建议所有的光电倍增管使用型号为#57-987(见规格)的电源。

典型应用包括拉曼光谱仪,流式细胞仪,荧光检测,辐射监测,半导体晶片检查和激光测距。

运作原理:

适合微光探测应用,光电倍增管(PMT)提供极高的灵敏度和超快速响应。光电倍增管包括一个光电阴极,在其之后一系列倍增器电极和电子集电极(阳极)在密封一个高度抽空的玻璃或金属罐中。当光线进入光电阴极的光电倍增管,光电子从阴极发出。这些光电子通过倍增器电极时由于次级电子发射而倍增,然后被阳极收集成为一个输出脉冲。光电倍增管的增益,是阳极输出电流和光电阴极中光电流的比值,直接关系到电源电压。光电倍增管一般运行在光电阴极与阳极存在500伏到1200伏直流或更高的压差下。光电阴极的构成决定光谱响应、每种波长的量子效应、光电倍增管灵敏度的均一性和暗电流。

警告:本产品对光极度敏感。室光下曝露光圈就会造成长期损害。应该只使用于光源小于1纳瓦(每个型号的最大光源输入功率见规格表,都在纳瓦或皮瓦的范围内)。外壳也很脆弱,如果跌落会造成长期损坏。上述原因造成的损坏不属于保修范围或退货政策。

Hamamatsu Photomultiplier Tube Modules

  • Wide Spectral Response
  • Fast Time Response
  • Low Dark Noise
  • High Sensitivity

Photomultiplier Tube (PMT) modules combine a PMT with a high voltage supply and often other signal processing electronics. A variety of PMT modules are available which differ in output signal format (current or voltage), spectral response, amplifier gain and bandwidth, as well as the size of the active area. 8mm Voltage and Current Output types feature 8mm head-on photomultiplier tubes, 1V/µA 20kHz low noise amplifiers, and can be fiber-coupled using either #57-567 SMA Adapter or #57-568 FC Adapter. 8mm Current Output types feature low ripple noise and fast settling times. 15mm Voltage Output types feature 15mm head-on photomultiplier tubes and 0.1V/µA 200kHz amplifiers. #57-731 4 x 20mm Current Output type is a high gain (107) PMT module suitable for use in broadband spectrophotometers and other precision photometric instruments. Rectangular active area PMT modules deliver high sensitivity with gains as high as 107 and fast response times. The recommended power supply for all the PMT modules is #57-987.

Typical applications include Raman spectroscopy, flow cytometry, fluorescence detection, DNA chip analyzers, multi-photon microscopy, radiation monitoring, semiconductor wafer inspection, laser range finding, broadband spectrophotometers and other precision photometric instruments.

Theory of Operation

Suitable for low-light-level detection applications, the photomultiplier tube (PMT) provides extremely high sensitivity and ultra-fast response. PMTs consist of a photocathode followed by a series of dynodes and an electron collector (anode) in a highly evacuated glass or metal can envelope. When light enters the photocathode of a photomultiplier tube, photoelectrons are emitted from the photocathode. These photoelectrons are multiplied by secondary electron emission through the dynodes and then collected by the anode as an output pulse. The gain of the PMT, that is the ratio of anode output current to the photoelectric current from the photocathode, is directly related to the supply voltage. PMTs generally operate with a bias between photocathode and anode of 500V to about 1200V DC or higher. The photocathode composition determines the spectral response, the quantum efficiency at each wavelength, the overall uniformity of photomultiplier sensitivity, and the dark current.

Warning: This product is extremely light sensitive. Exposing aperture to room light will permanently damage product. Should only be used with sources less than 1 nano-watt (see specifications for maximum light input per model, all are in nano-watt or pico-watt range). Housings are also fragile, and will be permanently damaged if dropped. Damages due to above reasons are not covered under warranty or return policies.
