IIRC the unit is specified to operate from 200 to 1100 nm and the grating gives about a 200 nm wide swath across the CCD. It is my understanding that it is possible to place that 200 nm sensing width anywhere within that overall range. When I get home tonight I can tell you these numbers more accurately, plus where I moved one of my units to.
These are amazing little instruments, IMHO, especially for the price.

I sure would like to be able to see into the near IR or near UV range.
