 Programmable Optical Tunable Filter OTF-920
|
The OTF-920 tunable filter features santec original "linear sliding" technology. It accommodates two optical "sliders", each of which is independently tunable. By equipping a tunable filter on one slider and equipping an variable attenuator on the other slider, simultaneous control of wavelength and power is provided.
OTF-920 equips GPIB and RS-232C control interface which enables remote control and data acquisition.
