SR540 | Optical chopper 4 Hz – 3.7 kHz

The SR540 Chopper is great for any optical chopping needs, including anything from simple measurements to inter modulation experiments as well as dual-beam. It has a four-digit frequency display, analog voltage frequency control, two reference outputs with varying operating modes and a front-panel frequency control. .sr540斩波器的任何伟大的光斩波的求包括从简单的测互实以及双光束的东。它有一四个数字率显示模拟电压率控制两个不同操作模式的参出和前板的率控制。。A five/six-slot blade is provided for frequencies up to 400Hz and a 25/30-slot blade for frequencies up to 3.7kHz, both of which are anodized aluminum for maximum durability. Also provided are reference outputs for corresponding frequencies to each row of slots and the sum or difference of frequencies.一五/六插槽刀片置率400Hz和25 / 30率3.7khz槽刀片两最大的用性极氧化。提供了相应的率每排槽或率差和参出。
