USPM-RU III
Panoramica
The USPM-RU III is a reflectometer that provides highly accurate spectral reflectivity measurements of small, curved, and thin samples without interference from rear surface-reflected light.

 Measuring Image | Measuring even minute areasThe curved surface of the lens can be measured from a minute spot as small as ø60 µm formed on the sample surface. This provides the ability to use a goniometer to examine even the curved side lenses or other optical component. |
 Principle of Eliminating Rear Surface Reflection | Reduces backside interferenceAccurate measurement of surface reflectivity can be performed without the costly steps that are typically needed to prevent rear surface reflection. Rear surface-reflected light is reduced by means of special optics that block out all out of focus light reflection similar to a confocal system. Whether your optical component is spherical, aspherical or flat the USPM-RU III does not require sample prep through anti-reflection treatments |
Fast Results
Quick, highly repeatable measurements can be achieved in seconds using a flat filed grating, line sensor and high -speed spectrophotometry.
 XY Chromaticity | X-Y Chromaticy Diagrams and L*A*B MeasurementObject color can be measured based on spectrophotometric colorimetry determined from the prismatic reflectivity. |
