光度计、放大器、显示仪表

光度计是一种特定类型的数字万用表(DMM),用于光辐射测量。连接的特定光检测器决定了波长范围/光谱加权功能和显示的测量单位。

我们提供模块化的宽带光探测器,可与我们广泛选择的光度计和放大器相结合。除了标准产品外,Gigahertz-Optik还提供定制解决方案。

第一步:作为第一步,我们建议选择一个探测头 。也可以使用几个探测头,这些探测头可以与单通道仪表互换使用,也可以与多通道仪表同时使用。探测头的选择标准包括所需的测量数量和范围、其光谱功能以及与预期用途相关的所有其他参数。

第二步:在第二步中,可以选择附件,例如,积分球。如果附件改变了探测头的测量范围和响应性,则必须选择相应测量范围的附件对探测头进行额外校准。

第三步:在第三步中,选择仪表。计划中的用途(如移动、固定、手动或遥控)、信号通道的数量、测量模式(连续、剂量、脉冲能量、时间性脉冲进展)都是决策标准。

第四步:测量设备与探测头的连接决定了探测头的连接器类型。Gigahertz-Optik的探测器设计有以下四种类型的连接器。

  • 连接器类型-1。传统的BNC同轴连接器
  • 连接器类型-2:带有Eeprom的校准数据连接器,用于存储由所连接的仪表读取的探测器数据(类型、校准的响应度)。
  • 连接器类型-4:紧凑型插头,用于最多有四个光电二极管的检测器头。
  • 连接器类型-5:带校准Eprom的紧凑型插头

Gigahertz-Optik 连接器

第5步:为了确定所选配置的测量范围,需要所选探测头和仪表的两个规格。探测头的典型灵敏度(如A/lx)和最大允许的信号电流。仪表测量范围内的最小和最大输入信号。

检测极限(噪声等效功率,N.E.P.)=仪表的最小输入信号(A)/典型的检测器灵敏度(例如,0.1 pA / 3 nA / (mW / cm²) = 0.33 nW / cm²。(*1) (*2)

最大读数=仪表的最大输入信号(A)/典型的探测器灵敏度(例如,20 μA / 3 nA / (mW / cm²)= 6.66 W / cm²。(*3)

备注。

(*1) 宽带测光仪或辐射计的最小可测值是由所需的信噪比(SNR)决定的。对于一个DIN A级测光表,例如,最小信噪比为100。对于本例计算的探测器头,信噪比为100意味着最小可测量值为33 nW / cm²。对于光辐射测量技术极限领域的应用,通常使用较低的信噪比,即50甚至10。

(*2) 在检测器电流信号很低的情况下,检测头和测量仪之间的电缆移动会导致短的、电容性的干扰信号。此外,探测头的插头上的应变效应可能会增加噪音信号。

(*3) 最大计算测量值反映了半导体光电二极管的大动态范围。然而,在实际应用中,最大可测量值往往受到被测光辐射中所包含的温度辐射的限制,这将意味着检测器头的不可接受的加热。
