光输出有CW、CHOP和EXT调制三种模式,其中CW是无调制的连续光输出,CHOP是270Hz调制的方波形的斩波光输出,EXT调制通过叠加外部输入连接器提供的信号使光输出的强度调制成为可能。4 .同步信号也以CHOP模式输出,当与锁相放大器一起使用时,可提供高灵敏度测量。
光输出端采用球面抛光(PC抛光)fc型连接器。通过使用球面抛光光纤进行外部连接,减少了反射光的影响,使稳定的测量成为可能。
There are three modes for light output with CW, CHOP and EXT MODULATION, where CW isthe continuous light output without modulation, CHOP is the chopped light output of a squarewaveform with 270Hz modulation, and EXT MODULATION makes modulation of the intensity oflight output possible by superpositing the signal supplied from an external input connector.4synchronized signal is also output in the CHOP mode to provide high sensitivity measurementwhen used with a lock-in amplifier.
A spherically polished (PC polished) FC-type connector is used for the light output terminal. Bymaking use of the spherically polished fiber for the external connection as well, the effect of thereflected light is reduced, making stabilized measurement possible.
