U-4100 UV-Visible-NIR Spectrophotometer

U-4100 is the highest-end model achieving high accuracy of which “Famous Hitachi Photometer”is proud. It is the best choice for the user who requires high quality data in the measurement of an actual solid sample, for example in the development of semiconductors, optical materials and new materials. The system lineup covers a wide range of wavelengths and sample sizes to be measured, and can satisfy various analytical needs by combining various special accessories such as an accessory for measuring transmittance and reflectivity and a sensitive integrating sphere which can measure in the ultraviolet region at a low noise level.

Features

U-4100 is a high-achiever in the measurement of fixed samples, and allows accurate measurement of polarization properties. This graph shows the reflectivity measurement results at an incident angle of 45° for a YAG laser, showing the reflection properties of S- and P-polarized lights from the mirror of a microfabricator. Each reflectivity is almost 100% at 1064nm. In the manufacture of optical components, it is very important to obtain accurate polarization property measurements.
