Variable Attenuators come in manual and motorized versions.
Press Release Summary:
Manual UVA-800-M and motorized UVA-800-CONEX ultrafast variable attenuators feature thin film polarizers that protect against exposure to contaminants. Polarizers are used in conjunction with half-waveplate to provide adjustable intensity ratio splitting of S- and P-polarized outputs, both of which have polarization contrast ratios over 1:450. Motorized attenuator includes rotational stage with CONEX(TM) controller/driver, which communicates with and is powered by computer via USB port.

Newport Introduces New Series of Ultrafast Variable Attenuators (UVA)
Irvine, CA - Newport Corporation, a worldwide leader in lasers and photonics solutions that Make, Manage and Measure Light®, introduces the first set in a series of ultrafast variable attenuators. Compact, robust, and easy-to-use, the ultrafast attenuators are available in manual (UVA-800-M) and motorized (UVA-800-CONEX) versions. The new attenuators are designed to address the challenge of safely attenuating the output of ultrafast amplifiers.
The new models of ultrafast variable attenuators are composed of specially designed thin film polarizers, zero-order achromatic waveplates, and high-precision opto-mechanics, enclosed in shuttered housings. Specially designed high-damage threshold, thin-film polarizers are pre-aligned in the sealed housing to minimize exposure to dust and other contaminants. The thin-film polarizers are utilized in conjunction with a half-waveplate providing continuously adjustable intensity ratio splitting of the dual S- and P-polarized outputs.
The P-polarized output passes through the first polarizer with negligible beam deviation and minimal dispersion. The S-polarized output is reflected off two polarizers in a parallel offset (1-in.) from the fundamental, with negligible dispersion. Both outputs have high polarization contrast ratios (greater than 1:450) and require no adjustment over the entire working range. For added functionality, the sealed housing includes a manual shutter for the S-polarized port and a removable beam dump on the P-polarized port.
The motorized version rotational stage has an integrated CONEX(TM) controller/driver, which is powered and communicates with a computer via USB port. A free NSTRUCT(TM) applet to control the stage is available for download from Newport's website.
