Tunable PowerArc™ Output Curves
You can customize a Tunable PowerArc™ Micro-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™ Micro-Illuminator. 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 PowerArcT Micro-Illuminator can deliver up to 10 milliwatts of tunable light output!

Higher Resolution Gratings Can Provide Higher Intensities
The data curves above are all from illuminators that had a 1,200 g/mm grating. You will note from these curves that doubling the bandpass, or slit size, typically results in a factor of four increase in intensity. This is true as long as the slit size is the same or equal to the optical spot size. Therefore if you used a 2,400 g/mm grating you would be doubling the slit size from a 1,200 g/mm grating to maintain an equivalent bandpass. Thus a Tunable PowerArc™ Illuminator equipped with a xenon lamp and a 2,400 g/mm grating blazed at 300 nm will give you up to 80 milliwatts of optical power in a 20 nm bandpass. However the 2,400 g/mm grating will only mechanically scan up to 600 nm, see monochromator for more details.
Still not sure the OBB Tunable PowerArc Micro-Illuminator will work for your experiments?
After learning this much about the Tunable PowerArc™ many people stop reading and just order one for themselves. But if you are still not 100% sure that this illuminator will work for your requirements, OBB Corporation is willing to provide all North American customers with a fourteen day evaluation in your lab with your own complete Tunable PowerArc™. If you place an order with us, you have a fourteen day period from when it is shipped during which time you can determine for yourself if the Tunable PowerArc™ is ideal for you. Within the 14 day evaluation period if you are not happy with the illuminator for any reason, or no reason at all, you can return it to us at no charge. It's that simple. This offer may not be available in all countries. |
