Therefore, the proposed methods of measuring the focusing constant of GRIN fiber lens and its application in designing GRIN fiber probes are validated and feasible to further developing ultra-small GRIN fiber probes requiring specific optical focusing performance.
The curve-fitting algorithm is adopted to measure the focusing constant of a gradient-index (GRIN) fiber lens, which is used to further design ultra-small GRIN fiber probes.
The results show that, in the given condition, the fitted value of the focusing constant of GRIN fiber lens and the theoretical focusing performance parameters of GRIN fiber probes, respectively agree well with the nominal value provided by the manufacturer and the experimentally measured data.

The desired gradient profile was confirmed by measuring the focusing positions of a standard protein for different counter flow rates at constant voltage.
Constants that are a combination of directly measured constants and also fixed constants.
Sales were down by 9.7% measured at constant currencies and dropped by 10.8% in actual currencies.
The previous year, international weapons sales were nearly $34 billion, when measured in constant year 2000 dollars.
Main Outcome Measures: Electromechanically measured absolute constant error, variable error, and equilibrium score.
