Description

The most time-consuming task is often the optical interface to the sample. Therefore, NLIR has developed a series of measurement bundles to ease that task. There’s no general optimal interface for spectroscopic measurements; different samples require different interfaces. NLIR has made several different custom solutions and many measurement tests for a wide range of applications in the industry. The best and most frequently used bundles have converged into the products shown below. Fiber-coupled probe bundle For small samples, NLIR has developed a fiber-coupled probe that measures in a small and well-defined area. The light is brought from the NLIR light source by fiber to the sample and collected again by fiber and brought to the NLIR spectrometer. This results in a fast and sensitive probing setup. The probing area can be as small as a few hundred micrometer and only that area is measured. The light that returns to the spectrometer has detailed information about the infrared properties of the sample. A typical measurement time with this setup is 100 ms. Fiber to and from sample Small measurement area Good for small or integrated devices Reflection bundle Measurements done in reflection from a given sample needs a powerful light source and a means to get the reflected light to the spectrometer. NLIR has designed an elliptical reflector optimized to be positioned 20 cm from the sample and illuminate and area of approx. 1 cm diameter. Reflected light is collected by the fiber head and sent to the spectrometer.
