OPTICAL SYSTEM

Double Monochromator Prism-Grating Optical System

 

 

 Offering low polarization effects and low noise measurements

The UH4150 adopts a prism-grating (P-G) double monochromator optical system, continuing the established reputation of the U-4100 optical system. Large changes in light intensity of the S and P polarization are less likely for the prism-grating (P-G) system than for the generally used grating-grating (G-G) system. The UH4150 offers low noise measurements, even for low transmittance and reflectance samples.

Collimated Light Beam advantage

High-accuracy specular reflectance measurement
The incident angle is important for the measurement of specular reflectance of solid
samples. For focused light beam, the incident angle varies depending on the lens’s focal length, etc. Consequently, the values of simulation of design of optical thin films, such as dielectric multilayer film and prism, would differ from actual measured values. In the case of a collimated light beam, however, the incident angle is always the same with respect to the sample, leading to a highly accurate measurement of specular reflectance. Moreover, the collimated light beam is useful for the evaluation of diffusivity (haze) and the measurement of transmittance of lenses.

 

Difference at Detector Switching due to Signal Level Suppression
Improved accuracy in the visible to near infrared spectral region
Multiple detectors are installed in the integrating sphere to perform measurement over a wide range of wavelengths, from ultraviolet to visible to near infrared regions. The changes in photometric values at detector switching (from signal level differences) are minimized due to a design utilizing Hitachi’ s expertise in integrating sphere construction, signal processing technologies, etc.
