Re: Alternatives to integrating sphere?

Greetings all,

Our research group is trying to calibrate a photodiode array for use on a microscope such that the detector elements can be normalized with
respect to one another. We've gathered that an integration sphere is the appropriate means to do this. We would position it over the
microscope objective which focuses the light to a fiber optic bundle which leads to the photodiode array.

However, we're having an internal debate about the cost of purchasing what is essentially a one-use device for our purposes. Are there
similar devices which can do the job but are more inexpensive? Or, barring that, can anyone provide brand names of inexpensive integrating
spheres?

Mark,

I would encourage you to visit www.labsphere.com and explore the
Knowledge Base. There is alot of good stuff there.

Labsphere can provide solutions ranging from WRC 680 coating that you
can apply to a sphere yourself, to modular spheres and components to
put your own system together, to complete calibrated uniform
illumination systems. You can call Labsphere and speak with an
applications engineer to discuss your application. I would also
encourage you to look on ebay, there are always integrating spheres
showing up there.

Best of luck.
