Transmittance Measurement of Rolled Plate Glass for Solar Cell Evaluating Multilayer Dielectric Films
Rolled plate glass is a plate glass with rough surface. When it is scanned by a small integrating sphere, large steps at the Multilayer dielectric films are used to coat lenses, mirrors, filters, and various other optical elements used in

In addition to rolled plate glass for solar cell, it is useful for measuring special fibers that cause diffusion. transmittance and absolute reflectance can be measured as the angle of incidence is varied for various light. The
results confirm that, because of the multilayer film structure, varying the incident angle changes which wave-

Shimadzu’s unique aperture design provides condensed light with an excellent signal-to-noise ratio, which
100.00 means it can be converted easily to highly collimated light to accommodate customer measurement requirements.

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 compo-
nent and a diffuse component. For mirrors, the specular reflectance is the reflectance component of significance. In Options Used for Measurements
addition, reflectance measurements can be made as relative to the reflectance of a background material or as absolute.
Absolute values of specular reflectance are determined by use of an absolute reflectance measurement (ASR) accessory. The ISR-1503 Integrating Sphere ASR-3105/3112/3130/3145 Variable Angle Measurement
