 Brooke,

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.

Hi John:

Can you elaborate on the "change the wavelength limits"?
I sure would like to be able to see into the near IR or near UV range.
