Tunable PowerArc™ Illuminator Specifications

 

Tunable PowerArc™ Output Curves

You can customize a Tunable PowerArc™ Illuminator to suit your specific needs. The lamp and grating selected primarily determine the performance of the illuminator. However for any given lamp and grating the slit adjustment (or bandwidth) selected will also affect the intensity output of the unit.

Below are a series of intensity output curves for different configurations of the Tunable PowerArc™ Illuminators. There are far too many variables to provide output curves for all possible combinations for these illuminators. If you are interested in an illuminator with a different grating than those shown below, then you can compare the grating curves of that grating with one listed below to get a pretty good idea of how your particular illuminator will perform.

The Tunable PowerArc™ Illuminator can deliver up to 10 milliwatts of tunable light output!

UV illumination down to 180 nm

Although the spectral output charts above do not show data below 250 nm, the PowerArc can deliver light down to 180 nm, the lowest available wavelength emission of the xenon plasma. Some arc lamps use quartz envelope bulbs that do not transmit UV wavelengths. These lamps are sometimes called ozone free bulbs because they do not emit in the deep UV and hence create ozone when interacting with oxygen in the air. We offer both ozone free and UV enhanced bulb choices, as well as different window materials for the front output of the lamp housing, so that our customers can choose the best components for their requirements.

For requirements below 250 nm please select from one of the two following xenon lamps when requesting your quote.
