Spectrometers, Sensors, Camera’s, Light Sources and more…
At NXT a whole department, works on custom-built solutions. This department does not only produce standard prototypes, but also complete measurement solutions to meet any individual customer request.
The program ranges from “basic” spectrometer up to special inline solutions, designed especially for you.
And which requirements do you have?
With quality in research, work and industrial manufacturing becoming more and more important, there is a growing demand for highly specified measurement tools.
If your industry has any difficulties completing tasks with standard equipment and with technology progressing more and more, simply get some advice from NXT. With over 20 years of experience and being the experts in spectrometric measurement solutions, we often realize apparently unrealizable wishes and requirements.
If you have any comments or questions, please do not hesitate to contact us.
ETA-ARC / ETA-ARC-AT
Process control and quality, with non-destructive sampling
NXT offers a unique contactless measurement instrument that can quickly and accurately measures spectral reflectance and color appearance of anti-reflective (AR) coatings, or coating layer thickness of hard coatings and varnishes on transparent and translucent curved surfaces.
- It successfully suppresses rear-side surface reflection, which eliminates the need to roughen or blacken the sample. This means that tested products can also be sold.
- Fast measurement of spectral reflectance, and evaluation of layer thickness and colorimetric data, enables larger QA samplings to be made – 100% if so desired.
- Comprehensive measurement documentation supports traceability and repeatability, making continuous process improvement possible.
The ETA-ARC-AT system consists of a spectrometer for the visible spectral range, a light source, and a unique proprietary sensing head. Light source and spectrometer are integrated in a desktop housing, and connected to the sensing head via optical fiber and electronics cables.
Integrated focus and tilt sensors respectively achieve the best possible photometric accuracy and repeatability, and ensure that reflected light always enters the detector aperture correctly, regardless of the curvature of the measured object.
The result of nearly two decades of spectrometer development and testing, followed by use in high-precision production environments, the instrument carefully records the reflectance spectra. Interpretation is then performed by a sophisticated software, which includes tools for calibration, data acquisition, and data evaluation. All acquired and evaluated data can be stored for documentation or exported to other applications.
