The 1621 Silicon Nanosecond Photodetector is similar to 350-1000 nm detectors with moderate gain and large bandwidth that many of us have built from scratch over and over again. It is ideal for use as a general purpose detector with Q-switched or CW lasers, and its large diameter and DC response make alignment easy. The user-switchable load resistor (50Ω or 10 kΩ) lets you optimize for response time or sensitivity. Choose a nanosecond response time with 50-V/A sensitivity, or a slower response time with a higher (10,000 V/A) sensitivity. The nanosecond rise time at the 50Ω load setting is fast enough to see your Q-switched pulses. Or use the 10-kΩ resistor setting for alignment purposes and for detecting lower-power pulses and cow light. We've even included an open-circuit setting so you can choose the best gain-bandwidth combination for your application. 8-32 mounting thread. M4 metric adaptor and tool now included.



1621纳米硅光电探测器类似于350-1000纳米的探测器，具有中等增益和大带宽，我们很多人都是从头到尾从头构建的。它是理想的用途与q开关或连续波激光器通用探测器，其大直径和直流响应，使对准容易。用户可切换负载电阻(50Ω或10 kΩ)让你优化响应时间或灵敏度。选择具有50 V/ a灵敏度的纳秒响应时间，或者具有较高(10,000 V/ a)灵敏度的较慢响应时间。50Ω的纳秒上升时间负载设置是足够快的看到你的q开关脉冲。或使用10-kΩ电阻器设置用于校准和检测低功率脉冲和牛。我们甚至还提供了一个开路设置，以便您可以为您的应用程序选择最佳的增益带宽组合。8-32越来越多的线程。现在包括M4公制适配器和工具。
