Refractive index of plastic materials
Measuring samples from thin ones up to 5mm thick! We can accommodate from film processing.
We measure the refractive index of plastic materials. The refractive index (the ratio of the sine of the angle of incidence α to the sine of the angle of refraction β at the interface when light travels from air into a substance) is a fundamental property that can be used for purity and composition testing, material identification, and the design of optical components. We can measure samples ranging from thin film samples to those up to 5mm thick, accommodating film processing. In addition to the refractive index, we also measure optical properties such as haze, color tone, glossiness, and transmittance. 【Measurement Conditions】 ■ Applicable Standards: JIS K7142 ■ Testing Environment: 23℃ ■ Sample Shape: Approximately 10mm × 20mm ■ Equipment: Abbe Refractometer 1T/Atago ■ Measurement Wavelength: D line approximation (approximately 589nm) *For more details, please download the PDF or feel free to contact us.
