Pass/Fail Judgment of Colored Film Using the Spectral Evaluation Function of LabSolutions™ UV-Vis Software

Introduction

Ultraviolet-visible spectrophotometers are used routinely in various industries for acceptance inspections of raw materials and quality inspections of products. In the materials and chemical industries in particular, ultraviolet-visible spectrophotometers are used as the reference for determining the transmittance of film and filters. However, inspections on such products require burdensome tasks after spectrum measurement, such as reading the transmittance of specific wavelengths or calculating the absorbance ratio of multiple peaks, in order to judge the acceptability of products. The LabSolutions UV-Vis software provides the spectral evaluation function as a standard feature so that inspections can be performed efficiently. This function automatically carries out analysis, including peak detection and calculation after spectrum measurement and makes a pass/fail judgment. This article introduces an example of pass/fail judgments on transmittance measurements of colored film using the spectral evaluation function.
