Product Specifications

High Resolution

IS-Instruments offer a range of high
resolution, high performance, bespoke
spectrometers for the most demanding of
spectral measurement problems. Spectral
resolution on the fm are possible.

The instruments use Fabry Perot technology combined with high
quality imaging detection systems to provide state of the art
spectral resolution while maintaining a high level of throughput.
Working with our partner IC optical systems both fixed and
tuneable solutions are possible offering unparalleled levels of
optical performance. Systems are available operating in the
region of 300 – 2000 nm with working diameters up to 200 mm!


These instruments typically contain an series of interference
filers combined with 1- 3 Fabry Perot etalons used in series to
provide both high levels of background suppression as well
as high resolution and transmission. Instruments are typically
mounted in a thermally controlled hermitically sealed container
to ensure maximum stability and control.

All systems are constructed bespoke to order.

As well provided the complete solution IS-Instruments also
offers a comprehensive design service to optimise the Fabry
Perot configuration that is required for the particular end user
