| Newport Introduces New Ultrafast Variable Attenuators (UAV) |
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™ controller/driver, which is powered and communicates with a computer via USB port. A free NSTRUCT™ applet to control the stage is available for download from Newport’s website.
