Introduction
A Fourier transform infrared spectrophotometer (FTIR) is often used for the material identification and the contaminant analysis of a film and a filter. On the other hand, a UV-Visible spectrophotometer is used to examine their optical properties such as transmittance and reflectance. Its example is the examination of transmittance of a long-pass filter which is an optical element and transmits light in longer wavelength range than a specific wavelength. Films and filters are utilized in many fields based on their properties. This report demonstrates pass/fail judgments of a band- pass filter and a long-pass filter using the spectra evaluation function of LabSolutionsTM UV-Vis and the color measurement of color cellophane films using the color analysis function of LabSolutions UV-Vis.
