UV-Visible/NIR Spectrophotometer UH4150AD Hitachi Japan
We
have released the UH4150AD spectrophotometer as an enhanced version of our
popular UH4150 spectrophotometer. The UH4150AD is customized for
high-absorption, ultra-low-transmission measurements. This instrument may be
used for characterization and quality control of optical films for band-pass
filters and cutoff filters.
Main
Features
- Allows measurements of
ultra-low transmission/high-absorption over a wide spectral range of 8 Abs
(UV/visible regions).
The use of a new grating-grating double monochromator reduces stray light
in the spectrometer, resulting in a high photometric range (8 Abs) in the
UV-Vis.
- Parallel beams allow
high-precision measurements of specular reflection.*1
By installing an integrating sphere on the UH4150AD, parallel-beam
measurements similar to those available on the current model*2 become
possible. In particular, the use of parallel beams ensures that the
incident angle is essentially uniform across the sample, allowing
high-precision measurements of specular reflection.
- The UH4150AD sample
chamber adopts the same structure as that of the sample chamber of the
current model.*2
The UH4150AD sample chamber was designed to adopt the same structure as
the sample chamber on the current model; this sample chamber was popular
among users for the ease with which it allowed large samples to be
positioned and the extendibility afforded by its vast range of
accessories.
