Ultra High Resolution Spectrometer

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 systems represent the state of the art of current interferometric technology and are ideal for the most challenging of ground based scientific measurement, from astronomical observations through to atmospheric LIDAR measurement.  Systems can be used both in an imaging and filtering configuration depending on the particular end user requirements.

 

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 needs.
