Ibsen offers a wide range of robust, athermal, industrial-grade OEM spectrometers that can be tailored to your exact needs. We are dedicated to being your preferred OEM partner for spectroscopic modules by offering a lot of competitive benefits.

Do you want to know about the benefits of transmission grating-based spectrometers?

See white paper

You can find more details about our spectrometer platforms below. We also offer extensive integration and support services as well as an OEM project model for customers that want us to develop a spectrometer variant.


  • High sensitivity/optical throughput due to our in-house produced fused silica transmission gratings

  • Proven, environmentally robust, and thermally stable opto-mechanical benches with low unit-to-unit variation

  • Volume manufacturing with high quality, consistent performance and flexible delivery

  • A dedicated OEM support team to assist you throughout your project development and manufacturing phases

  • Senior level optical and mechanical design experience

Spectrometer platforms

We base our OEM spectrometers on a range of basic platforms as well as the ROCK, FREEDOM, PEBBLE, PEAK, and EAGLE series of standard spectrometer configurations. On our application pages, you can find help to identify which of our spectrometer platforms best suits your needs.

Compact spectrometer



The PEBBLE spectrometers combine an ultra compact form factor of only 17 mm x 15 mm x 8 mm with high resolution and sensitivity as well as environmental ruggedness.

Compact spectrometer



The FREEDOM spectrometers combine compactness and low cost with high performance. They are an ideal OEM solution for handheld and portable systems.

PEAK XNIR OEM spectrometer



PEAK enables a new dimension of programmability in spectroscopic instruments that have not been possible with any other technology on the market.

ROCK NIR spectrometer



Due to a low f-number of 2.2 and highly efficient transmission gratings, the ROCK series offers very high throughput – typically 4 times higher than conventional Czerny-Turner-based designs.

High resolution Raman spectrometer



The EAGLE spectrometers are robust, athermal, industrial grade, diode array based spectrometers especially well-suited for SD-OCT and Raman spectroscopy, due to a high optical resolution.

Which spectrometer to use?

Do you need to evaluate a spectrometer for your next project?
We understand that it can be hard to judge the performance of a spectrometer just from the data sheet. Therefore, we offer a time limited loan of a demo unit to customers that meet certain criteria.
