Applications that use spectrometers to measure the light energy of radiant sources require an irradiance-calibration, because the uncalibrated intensity response of the spectrometer includes contributions from the spectrometer internal optics spectral transmission and detector spectral response.

Starting from 2020, FTIRs from ARCoptix include a top desiccant port, that allow using the instrument without nitrogen line. For some customers however, the residual moisture level achieved with desiccants is not sufficient. This document shows how to install a nitrogen purge line on the FT-MIR Rocket or any instrument equipped with a top desiccant port.

This application note describes the use of ARCspectro FT-NIR and FT-MIR for measuring modulated (or pulsed) light sources.

The Arcoptix OEM-ATR-20-12 spectrometer is an ATR (attenuated total reflection) version of the Arcoptix very successful range of spectrometers, adapted for measurements of liquids. This Application note is documenting the use of this spectrometer for measurement of diluted CO2 in water.

Our FT-NIR Rocket fibered Fourier-transform spectrometer is a great tool for mineral identification in rock samples. It offers a very broad spectral range of 900 to 2600nm together with a high resolution, both of which are highly desirable features in this application field.

The Arcoptix GASEX HD-05-xx spectrometers are specialized gas spectrometers used for a range of applications.

Diffuse reflectance (DR) measurement is a primary field of analysis in infrared spectroscopy, that offers access to a large compound of information from various solid samples such as minerals, plants, plastics etc.

Fourier Transform infrared (FT-IR) spectrometers have proven to be efficient and reliable tools for a large variety of applications targeting the near infrared (NIR) and mid-infrared (MIR) regions of the electromagnetic spectrum.

Laser sources can be measured by directly shining laser light into the spectrometer via an optical fiber or through the free-space input port. There are however two key limiting aspects to take into account.

The FT-NIR fibered spectrometer from Arcoptix represents a convenient and flexible tool to perform accurate diffuse reflectance measurements on a broad variety of samples and materials.

Infrared spectroscopy is an ideal tool for characterizing textiles for identification or classification purposes. Here, we showcase how the ARCoptix FTIR can be used for such purpose both in the near-infrared (NIR) and mid-infrared (MIR) without using contact sampling methods.
