With a wavelength range of - 3, nm, measurements are possible over a wide range including the ultraviolet, visible and near infrared regions. This allows spectroscopic analysis in a wide variety of fields. The UV Plus is designed mainly for the measurement of liquid samples.
But a wide range of accessories, such as the multipurpose large-sample compartment MPC with integrating sphere and three detectors, enables measurement of solid samples. With the guaranteed precision of the ASR Series Absolute Specular Reflectance attachments, high accuracy absolute reflectance measurements are possible.

The figure shows the results of a transmission spectrum measurement on a micro-sensor window. When small samples are measured, the size of the light beam must be adjusted to the size of the sample.
A Wealth of Applications E le ct ric al, Elec tronic s, and Optic s Absolute Reflectance Measurement of Mirrors The reflectance of mirrors used in telescopes, lasers, and some other devices is extremely important because it serves as a factor in determining their performance.
The total light reflecting off of a sample can be composed of a specular component and a diffuse component. For mirrors, the specular reflectance is the reflectance component of significance. In addition, reflectance measurements can be made as relative to the reflectance of a background material or as absolute Ele ct ric al, Elec tronic s, and Optic s Band Gap Calculation Research into solar-cell and photocatalytic materials often involves the measurement of the band gap, which is a basic physical property of the materials.
Shown below are the diffuse reflectance spectra of three semiconductor materials used in the production of solar cells using the ISR integrating sphere. The absorption edge, the wavelength where the reflectance decreases, differs depending upon the sample type. The band gaps of the samples were A Wealth of Applications C h emic als Thickness Measurement of Plastic Wrap for Food Packaging Interference wave patterns sometimes occur when light passes through a thin, transparent film.
The film thickness of a sample can be determined from the wavelength intervals of these interference wave patterns. The figure shows the transmittance spectrum of plastic wrap for food packaging.
An interference wave pattern can be seen. By utilizing the optional film thickness measurement software, the film thickness was calculated to be Note: The refractive index of the sample must be entered Your most recent searches Delete.
