火焰探测器UV Detector

　　 利用金属光电与气体倍增两个效果的紫外传感器。其感应波长为185-260nm,所以不用像其他半导体器件那样还要使用可见光的遮光片。具有体积小,灵敏度高的特点,可以检测从火焰发出的微弱紫外线,比如5米以外的打火机。主要用途为,火灾报警,燃烧监视,紫外开关等。

A ultraviolet detector that makes use of the photoelectric effect of metal and the gas multiplication effect. It has a narrow spectral sensitivity of 185 nm to 260 nm, being completely insensitive to visible light. Unlike semiconductor detectors, it does not require optical visible-cut filters, thus making it easy to use.

紫外探测器能很好的探测200nm-380nm光谱范围的紫外线辐射，并产生光电流。但对这个光谱区域以外的紫外线辐射不敏感，例如可见太阳光以及室内照明光源。它的高灵敏度,宽响应光谱范围，密封封装，小尺寸，低价格，宽工作温度范围以及能长期暴露在紫外光辐射的特性很适合工业和消费类紫外线探测应用。

一、特点：

·高灵敏度高，

·各种滤波器窗口可选，能提供具有UV-A、UV-B、UV-C和 UV-BC(包括B&C波段)滤波器的标准产品

·抗辐射类型，在高强度紫外辐射条件下，具备长期稳定性

·带透镜类型，具有非常高的灵敏度，特别适合低强度紫外光探测

UV photodiodes, SiC photodetectors, ultraviolet detectors
Silicon Carbide (SiC) Detectors
Silicon carbide SiC photodetectors / photodiodes have a spectral
response of approximately 210 -380 nm and are not sensitive to UV radiation outside this region. This makes them ideal detectors in certain applications for monitoring the UV spectrum without the need for solar rejection filters. SiC photodetectors are extremely durable and have been proven to withstand prolonged UV exposure in production quantities in many applications.
