The
UV-VIS-NIR scanning spectrophotometer is a universal instrument designed
specifically for unattended measurement of optical parts with coatings. The
instrument is produced in six configurations relative to effective spectral
range meeting individual customer measurement needs - from 380-1700 nm up to
190-4500 nm.
The
configuration of the spectrophotometer in many respects changes the approach to
the simplicity, versatility and speed of measurements. The measurement of
absolute reflectance and transmittance at variable angles and polarization modes
are carried out unattended and without any additional assemblies.
Original optical scheme of the spectrophotometer includes a reference channel
and provides for study of optical parts from 10mm up to 120mm in diameter.
Extensive QA/QC analyses, research and development of advanced thin film
materials is supported with the built-in determination of n, k, and d parameters
in the UV-VIS-NIR range with spectrophotometric reverse engineering.
The
spectrophotometer ensures trustful measurements with a spectral resolution up to
1.2 nm, photometric accuracy to 0.0050 and repeat accuracy up to 0.0025 in
transmission mode meeting the modern requirements for various research studies.
The
instrument is very compact and convenient for everyday use. The body with a
large lid offers easy and unobstructed access to the measuring compartment
allowing the optical parts to be placed quickly and securely.
The 2
year warranty is provided as standard.
