Metering UV Exposures with a Solartech Model 5.0 Solar Meter
Well as a christmas gift to myself I picked up a Solartech Model 5.0 solar meter on eBay for $45 (retails for $179.. so not bad eh!) -> http://www.solarmeter.com/model5.html
The idea for metering UV exposures for alt process printing came to me a while back and I posted some original thoughts in this thread.
This meter is designed mainly for testing the UV output of tanning beds and that kind of thing. But the meter is well suited for processes that use dichromate sensitization and probably others like cyanotype, Pt/Pd, etc. This meter has a peak sensitivity of 370nm and output values in milliwatts/cm².
But now comes the hard part; figuring out how to make good on these readings.
I think the biggest advantage is going to be the ability to know the UV activity of daylight and to use that information to make accurate sunlight exposures. But getting from the readings to a reliable exposure table is going to take some testing and I'd like your input on devising some methods to get to this point.
