1. PURPOSES AND FEATURES
1.1 Intended uses of this product
Lens Spectral Reflectivity Measurement USPM3-100/USPM3-200 is intended to measure
the reflectance of a coated plane. Through easy operations, the reflectance of a subject
is calculated in comparison to that of the reference sample.
1.2 Features
This device has the following useful features:
Short measurement time
Use of high-speed spectrometry based on a flat field grating and line sensor enables
the measurement to be finished within a short time.
Cutout of rear surface reflection noise
The device employs zonal illumination to cut out rear surface reflection noise.
Therefore, it allows to accurately measure the reflectance of the front surface only,
without the need for antireflection treatment on the rear surface or any other
countermeasure.
Reflectance measurement of minute area
The objective forms a spot of approximately 60 [μm] (when the 10x objective is
employed) on the surface under measurement. This allows to measure also lens
curvatures and coating unevenness.
Flexible comparison measurement
Since the reflectances of different comparison measurement masters can be set up
as reference values, the device can be applied to comparison measurements with
flexibility.
The product is intended to measure spectral characteristics,
including reflectance. Do not use for any other purpose.
