Farfield's Philosophy of Measurement

Dual Polarisation Interferometry is Farfield's first technology to market, but is only one of a range of high-resolution measurement techniques in development at the company.

Farfield's approach to the creation of quantitative, high-resolution tools for the study of molecular structure has been acclaimed worldwide across both the Biophysics and Surface Science communities. It is based on a rigorous understanding and independent verification of the underlying physics of metrology at the sub-atomic scale. It is born of knowledge that such metrology is rarely accomplished with a single analytical method, and therefore results need to be quantitative so that they can be compared with complementary measurements. Our belief is that our measurements should be traceable to national and international standards so that they can be deployed in confidence.

Farfield is cognisant of the fact that metrology at the extremes of resolution to which we aspire commonly perturbs the very system being measured, and we take great care to avoid this. Measurement confidence requires a level of instrument stability commensurate with the required resolution, and this stability is something that we independently monitor as data is acquired on all of our instrument systems.

Farfield's philosophy of measurement extends beyond the measurement itself; it also encompasses the accessibility to such data. Software automatically resolves the optical signature of molecular function into the quantitative units of molecular size, density and mass without necessarily requiring a detailed knowledge of the underlying physics as verified by others. All data is recorded in both raw and processed form, for those wishing to gain access to the measurements at their most fundamental level. Our growing worldwide community of users is encouraged to share its experiences, help to drive the continued development of our analytical capability and share our vision to deliver higher fidelity insights into molecular function through a detailed knowledge of their structural behaviour, truly 'illuminating the molecular world...'
