Performance and peace of mind for a decade to come

The Thermo Scientific LightDrive optical engine is composed of a rugged and ultra-reliable interferometer, a novel single-point infrared source and a durable solid-state diode laser. These 3 components come with 10-year warranties, setting a new standard for low cost of ownership. The Nicolet iS20 Spectrometer delivers data reproducibility sample after sample with the LightDrive Optical Engine. 

 Technical Note: LightDrive Optical Engine

Familiarity you want – compliance you need

The Nicolet iS20 is powered by Thermo Scientific OMNIC Software. Seamlessly transfer methods, workflows and libraries to the latest version of OMNIC. Also included with the Nicolet iS20 Spectrometer are Thermo Scientific OMNIC Specta for multi-component analysis and OMNIC Anywhere, our cloud-based spectroscopy software, which enables you to analyze and share data anytime, anywhere.

We made compliance easier with automated systems that meet international regulations. Regulated laboratories must have absolute confidence in the answers they provide. Thermo Scientific Security Suite Software allows you to ensure the security and integrity of your data and helps your lab comply with 21 CFR Part 11 or other regulations.

Familiarity you want – compliance you need


FTIR spectroscopy offers almost unlimited analytical opportunities in many areas of production and quality control determining if a product meets control specifications. An advantage of FTIR is fast data acquisition for both qualitative and quantitative analysis. Create custom methods for each step of QA/QC testing for adherence to strict SOPs.



Perform raw material identification and deploy methods for product verification with confidence. Qualification tools help you comply with pharmacopeia regulatory requirements. Confidence in instrument installation, operation and performing according to specifications.



Understand and control chemical properties when designing new materials. Catch changes in additive formulations, degradation of multi-layer polymer composites, weakened packaging materials and effects of process curing times on polymer specifications.



Infrared spectroscopy is a valuable technique for monitoring air quality, testing water quality and identifying plastic particles.
