Critical Angle Refractometry for Lossy Media with a Priori Known Extinction Coefficient

open access: yesPhysics, 2021
Critical angle refractometry is an established technique for determining the refractive index of liquids and solids. For transparent samples, the critical angle refractometry precision is limited by incidence angle resolution.

Use of refractometry for determination of psittacine plasma protein concentration

open access: yesVeterinary Clinical Pathology, 2008
Previous studies have demonstrated both poor and good correlation of total protein concentrations in various avian species using refractometry and biuret methodologies.The purpose of the current study was to compare these 2 techniques of total protein ...

Assessment of gas molar density by gas modulation refractometry: A review of its basic operating principles and extraordinary performance

open access: yesSpectrochimica Acta, Part B: Atomic Spectroscopy, 2021
A technique for high-precision and high-accuracy assessment of both gas molar (and number) density and pressure, Gas Modulation Refractometry (GAMOR), is presented.

Gas modulation refractometry for high-precision assessment of pressure under non-temperature-stabilized conditions

open access: yesJournal of Vacuum Science and Technology A: Vacuum, Surfaces and Films, 2018
The authors report on the realization of a novel methodology for refractometry-GAs modulation refractometry (GAMOR)-that decreases the influence of drifts in Fabry Perot cavity refractometry.

(Near) Real-Time Snow Water Equivalent Observation Using GNSS Refractometry and RTKLIB [PDF]

open access: yes, 2022
Global navigation satellite system (GNSS) refractometry enables automated and continuous in situ snow water equivalent (SWE) observations. Such accurate and reliable in situ data are needed for calibration and validation of remote sensing data and could ...

Short communication: Comparative estimation of colostrum quality by Brix refractometry in bovine, caprine, and ovine colostrum.

open access: yes, 2021
Newborn ungulates depend on the timely supply of colostrum containing sufficient immunoglobulins to obtain passive immunity against disease. Brix refractometry enables a rapid on-farm estimation of colostrum quality and has been intensively studied in ...

Evaluation of the agreement between Brix refractometry and serum immunoglobulin concentration in neonatal piglets [PDF]

open access: yes, 2021
Neonatal piglets lack immunoglobulins at birth. Sufficient colostrum intake (CI) and immunoglobulin absorption are essential for an appropriate passive transfer of immunity via the colostrum.

A VIRTUAL SIMULATOR AS A TOOL FOR TEACHING REFRACTOMETRY [PDF]

open access: yes, 2017
Significance: Several educational technological innovations are developed with the purpose of contributing to the training of future optometrists and ophthalmologists. However, very little is available for teaching refractometry.

Fabry-Perot-cavity-based refractometry without influence of mirror penetration depth

open access: yes, 2021
Assessments of refractivity in a Fabry-Perot (FP) cavity by refractometry often encompass a step in which the penetration depth of the light into the mirrors is estimated to correct for the fraction of the cavity length into which no gas can penetrate ...
