UV sensitivity of a Nikon D70
« on: February 22, 2018, 02:33:59 pm »
The UV sensitivity of a Nikon D70 was measured by using a Hg spectrum. The camera was used without a camera lens in an open spectrometer configuration, consisting of a quartz lens, a reflection grating and a Hg high pressure lamp as a light source:



In addition to the 436 nm and 404 nm lines of the Hg spectrum, the 365 nm line of the Hg spectrum in red is clearly visible.

I expect that  you already know about this lens, but just in case: there is a Nikon 105mm f/4.5 UV-Micro-Nikkor .

The transmission is just under 60 percent at 220nm, rising to peak at between 320nm to 400nm with transmission at 66 percent, and from there it remains above 60 percent well into the infrared

This lens is made up with six UV grade optical elements with the first three made of Fused Silica (Quartz), the remaining are of synthetic Calcium Fluoride (CaF2).

Unfortunately the price of this 105mm UV Nikkor is very high.

The UV sensitivity of a modified Nikon D70 was measured:



In addition to the 436 nm and 404 nm lines of the visible Hg spectrum, the 365 nm line of the Hg spectrum and two new UV lines in red (false colour) are clearly visible.

Here you can modify your Nikon D70 or do it yourself:

That is about a IR conversion, did you use a different filter for UV or no filter at all?

This modified Nikon D70 is now a full spectrum camera, IR VIS UV.
