SRI 6008 Ozone Standard Reference Photometer | NIST The NIST Standard Reference Photometer (SRP) is a photometric instrument that accurately measures concentrations of ozone (O 3) in air up to 1000 nmol mol by absorption of the 253 7 nm mercury line The measurement principle is based on application of Beer-Lambert Law using an absorption cross-section of 1 147 x 10-17 cm 2 molecule The NIST SRP
SRI 6011 Josephson Arbitrary Waveform Synthesizer | NIST The Josephson arbitrary waveform synthesizer (JAWS) is an instrument that synthesizes ac voltage waveforms and dc voltages whose metrological accuracy results from pulse biasing thousands of series-connected superconducting Josephson junctions into their identical quantum states Technical Contact: Paul Dresselhaus Specifications Certificate (PDF Format) For SRI 6011 series costs, see below
Definitions | NIST NIST distributes and makes available for sale Standard Reference Instruments developed by NIST SRIs are versions of an instrument used at NIST to realize and disseminate a measurement unit An SRI offers the same or near levels of accuracy and precision achievable by the related NIST measurement service
SRI 6012 Precision Semiconductor Nanostructures | NIST SRI 6012 Precision Semiconductor Nanostructures Technical Contact: Kris Bertness Precision semiconductor nanostructure arrays are grown by molecular beam epitaxy (MBE) on a prepatterned substrate Following buffer layer deposition, the substrate is coated with a mask layer that allows selective regrowth in areas where the mask has been removed
