UV sensitivity of a Nikon D70
Physikfan, Thu Feb 22 2018, 01:53PMThe 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 visible 436 nm and 404 nm lines of the Hg spectrum, the UV 365 nm line of the Hg spectrum in red is clearly visible.

Is the IR blocking filter still in the camera?

I think so, this camera is not a modified one.
This red, wrong colour line is an UV line.

It is fairly easy to remove the filter so could be worth the trouble if the camera is not in common use for other things.

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.

Excellent that is what I was hoping for.

The calculated spectrum from the picture above recorded by this modified Nikon D70:
As you can see, these UV lines are at 365 nm, 334 nm and 313 nm.

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