Can anyone reccomend a unit with full uv wavelength capabilities?

The UV-3600 UV-VIS-NIR Spectrophotometer seems to be pretty decent.

Is has a range of 185 nm - 3300 nm.

Ultraviolet 10 nm - 390 nm
Visible 390 - 750 nm
Infrared 750 nm - 1 mm

Does anyone know of a unit that covers the full band 10nm to 1000nm+?

Unless you have an evacuated system, you're not going to go below about 190 nm (O2 starts to absorb down there) or much above 700 nm (water vapor).

There is no such spectrophotometer in one unit.
Spectrophotometers are divided into several categories :
X-ray , UV-VIS , VIS , NIR , IR etc. depending on their wavelenght range.
Most UV-VIS spectrophotometers covers the range 200nm to 1100nm.
Practically below 200nm is useless in a QC laboratory.

It is difficult to make an instrument covering hole range because it requires several light sources , x-ray , deuterium , tungsten, IR heating elements etc.
Also it will require several monochromators and straylight filters each covering different wavelenght ranges.

why to look for such an instrument is the interesting question that comes to mind
why would one need it?
