Case Study
Raman module prototype development

Putting concept to the test

Many industries, particularly chemical and pharmaceutical, use spectrometry to analyze the properties of raw materials. Recognizing the need for an easy-to-use, flexible instrument to meet a growing range of applications, Thermo Scientific developed the Nicolet™ iS™50 spectroscopy system.

The revolutionary design includes many new features, including the capability to add modules that expand the operator’s analysis toolkit. Realizing it was a massive development project, Thermo Scientific outsourced some of the design to allow its engineers and scientists to focus on the instrument’s core functions.

Delve assisted the company’s engineering team by creating a proof-of-principle (POP) prototype for the Raman module. The Raman subsystem contains a powerful infrared laser, a precision three-axis sample positioning system and sophisticated optics to capture light scattered off the sample and deliver it to the main instrument for spectral analysis.

We delivered a complex POP model that Thermo Scientific's team used to validate performance before designing the final product.

Developing this technically complex module required considerable electrical and mechanical engineering expertise as well as advanced prototyping capabilities. At Thermo Scientific’s request, we searched for a commercially available positioning system that could be customized to the instrument’s specifications. Finding no viable option, our engineering team created concepts that Thermo Scientific’s engineers took to completion.
