Computer Controlled Auto-variable Optical Fiber Attenuator Sep 30, 2009

It is a computer controlled easy to use equipment for the continuous, automatic attenuation of the laser output power.

the PC controlled closed loop attenuator sets and maintains the power by positioning the 1/2 wave-plate based on a feedback signal from a photo detector.a spectrometer is integrated into the setup which provides real-time information about the wavelength of the laser.the sc optical attenuator,st optical attenuator,fc optical attenuator,lc optical attenuator and mu optical attenuator are used in multiphoton microscopy and ultra-fast spectroscopy.
