I had added a post to this, but I guess I went of to find something an didn't finish it off, all lost now.
Basically Adafruit can guide you through the UVA region, they and then you get the sensor code, there is one that doesn't A & B bands and so should work for you you may need to provide your own index. I think it had a LUX (white light) reading
SI1145 can get you some broadband readings across all be the longest wavelength.

But loads to look through
As for IR, look for a dedicated detector, e.g. a PIN InGaAs photodetector in the two regions, 940nm and 1.25um by checking the peak and spectral curves.
Just looking at companies I made the wafers for years back and Hamamatsu have an I2C version covering both regions, again create you own index/intensity/luminance numbers.
It depends what you are trying to do, check out spot size, max intensity etc.
Is it just environmental monitoring?
