Source 4 Lens Test

Hi,

I recently started working in a theater that has been operating for quite a few years now. At some point, the barrels of all of the Source 4's were opened and cleaned but the lenses were mixed up. Just wondering if there is a way to test what degree a lens is, so they can be put back together correctly. Thanks for any help anyone can give.

Hi there,

You can find a handy document here - http://www.etcconnect.com/docs/docs_downloads/manuals/S4_Lens_Tube_Product_Update_RevB.pdf

This should give you the info you need to re-build your lens tubes.

My apologies for not specifying. The dots have been washed off of most of the lenses.

Thats unfortunate...take at look at the below article. You can try to hold the lens under a hanging light and the measure the focal length.
