ISS-2 Integrated Sampling System
The ISS-2 I NTEGRATED S AMPLING S YSTEM is a fully integrated 1-cm cuvette holder and tungsten halogen light
source. It couples to our spectrometers with optical fiber to create a small-footprint systems for VIS-NIR (~360-
1100 nm). The ISS-2 has a 900 hour bulb. Also, in the ISS-2, the fan is not enclosed in the base; it is exposed and
should be handled with care.
Parts Included
" ISS-2 cuvette holder and light source assembly
" 12VDC wall transformer for providing power
" 1-cm square, plastic cuvette for holding samples
" Screwdriver for adjusting the fit of the cuvette
" Allen wrench for adjusting the collimating lens
Operation
Attaching the Fibers
1. Attach a SMA-terminated optical fiber to the collimating lens.
2. Attach the other end of this fiber -- the read fiber -- to the spectrometer.
Adjusting the Fit of the Cuvette
The ISS-2 is preset for use with a 1-cm cuvette. When properly adjusted, the cuvette should fit snugly into the holder.
1.
Locate the two ball plunger screws.
2. Use the screwdriver to loosen the two ball plunger screws until the ends are visible in the holder.
3. Insert your cuvette into the holder.
4. Tighten the screws until the ball contacts the cuvette and starts to compress. Do not over-tighten.
Installing Filters
1. Loosen the filter clamping screw with an Allen wrench.
2. Insert the filter into the filter slot. The filter slot can accommodate filters up to 6 mm thick.
3. Clamp the filter in place by gently tightening with an Allen wrench.
Turning On the Lamp
1. Plug the wall transformer end into a 110 V outlet. Plug the 12 V output end into the back of your ISS-2.
2. Screw a fiber into the SMA connector.
3. Find the on/off switch on the back of the lamp and turn the lamp on.
Replacing the Bulb on the ISS-2
1. Order a replacement bulb.
2. Turn off the lamp and allow it to cool.
3. Remove the fan from the bottom of the lamp by loosening the four screws securing it to the base. Two of the
four screws also hold the two front legs in place. Once the screws are loosened, gently pull the fan, along with
the legs, away from the lamp.
4. Now that the fan is removed, use an Allen wrench to loosen the set screw that is underneath the fan. This screw
holds the bulb in place. You do not need to remove the set screw -- loosening it is sufficient.
5. Locate the two set screws at the back of the lamp, one above each back leg. These two screws keep the two
halves of the lamp together. Remove the two screws.
