Essentials - Accessories for all applications

With the introduction 20 years ago of the first spectrometers, Instrument Systems had already conceived the idea of launching the light into the spectrometer using fiber optics. Over the years, a comprehensive range of optical probes and measurement adapters has been developed and optimized for the most diverse variety of applications. With the appropriate accessories, a simple spectrometer can be transformed into a flexible measurement device that can be quickly and conveniently configured for the desired application.

Instrument System's innovative fiber optic connectors offer an additional benefit. The calibration of the spectrometer together with the corresponding accessory is not lost when changing the accessory. This feature is achieved by providing a kinematic and stable connection of the fiber to a proprietary fiber plug adapter, thus ensuring a mechanically precise and reproducible connection to the optical input port of the spectrometer.

The following table provides an overview of the available accessories:
