Let’s start a separate thread to document exposure unit/lamp specs and performance. I’m getting my NuArc 26-1KS setup and will be able to report back some real world performance very soon, but thought I would go ahead and share these details.
The main difference between a 26-1K and a 26-1KS is the lamp. 26-1k uses a mercury vapor lamp, the 26-1ks a metal halide lamp. I don’ have the spec on the mercury vapor lamp, but do know the metal halide lamp part number is NP80. Attached is the spectral response info. Looks like it’s main output is between 350nm and 400nm.
As soon as I have made some calibration prints I’ll report back on how the mater curve works with this setup.
