DIY UV light meter for alternative photographic processes

[Drew Wiley]

For printing purposes, UV integrators also have to handle a lot of potential heat too. I think a dedicated unit would have real advantages in this respect, not to mention that high-UV is a form of torture to many plastics etc.

If you don't think common window float glass doesn't pass a lot of UV, just set a color print in window of direct sunlight for a few months, or even bright fabric. We all know what that does! - written while I'm wearing specially coated reading glasses which mitigate computer and neo-lighting UV and excessive blue.

All I know, which is little, is about 50 very serious Alt Process printers bought the one I bought. Follow the herd. I already posted the link. The maker resumed production due to high demand.

I bought one to use in Sunshine and to be able to adjust print times to changing Sunshine UV content, by sky condition, the angle of sun and distance. Meaning clouds or not and time of year.

Where I used to live I could not use the Sun, as anything left outside was stolen in moments. Now I seem to have a bit of privacy, pronounced in the English manner.

I have a porch with south and west vistas. The Darkroom is 20 ft away.

I know OP is proposing his DIY, and I think you all know I like DIY, but if off the shelf works, DIY may be the long road.

OP please carry on. Sorry to interrupt. I have a saying, Never stop a man, woman or child from working. They are so hard to restart.

I use ML8511 sensor with a good spectal response near 360nm.

A glass stop a part of UV but all the printing frame have a glass and work with alternativ photography that's used UV, the UV blocked by the glass it's not in the used UV range of processes. In my printing frames i use standard basic home glass.

The alternatives process i use to have a sensibility at 360nm like this sensor, the UVB influence is poor in this case and in the final version i place a glass behind the sensor to protect and have the same configuration as the printing frame.

Thanks for your comments

I want the final version when you complete, I see the need for this...

should ask is there a current commercial unit that you are aware of??

Yes there is a current commercial version.
I probably would get in trouble if I gave you the name and website.

Jim, we can post some things. eBay is the big no-no, I believe.
