Is There a UV Lamp that Can Generate 150 nm Light for Bandgap Measurement?

[leright]

Is there a UV lamp (not a synchrotron) that will generate UV light down to say 150 nm? I need a light source to do optical characterization (bandgap measurement as a function of temperature) of a wide bandgap semiconductor (~6.2 eV), so I would prefer a light source below 200 nm, ideally around 150 nm. Is there such a thing?

Thanks.

A google search yielded the following;

Some models go down to 112 nm.
