UVAs Handle UFAs

Safely attenuating the output of ultrafast amplifiers (UFAs), the manual UVA-800-M and motorized UVA-800-CONEX ultrafast variable attenuators (UVAs) employ special thin-film polarizers, zero-order achromatic waveplates, and high-precision opto-mechanics.  The thin-film polarizers operate in conjunction with a half-waveplate providing continuously adjustable intensity ratio splitting of the dual S- and P-polarized outputs. The motorized version rotational stage integrates a CONEX controller/driver, which derives powered and communicates with a computer via USB port.  A free NSTRUCT applet to control the stage is available for download from the company’s website.
