| StellarNet Inc. offers a low-cost, rugged, CZ ATR (cubic zirconia
attenuated total reflection) probe that is ideal for use in an industrial process
environment. It is capable of operating at temperatures from -50°C to 300°C and at
pressures up to 1200 psi. This
outstanding performance is achieved by using Kalrez® O-ring seals. The CZ ATR probe is a three-bounce design, which affords a total
path length of approximately 1.5 microns. Cubic zirconia allows response down to 380 nm in
samples with an index of refraction up to 1.9, as well as offering excellent resistance to
chemical attack. The optical fiber is 400-micron core fused silica and is clad in
stainless steel armor. If needed, the armor can be sealed with Teflon® to provide a barrier to the environment. A four-inch
extension tube is added to the rear of the probe to allow direct insertion into a process
stream. The extension tube can be adapted to the customer's process connection
requirements.
TECHNOLOGICAL INNOVATIONS
The CZ ATR probe is constructed such that it requires no internal optical
elements other than the cubic zirconia hemisphere. This makes the probe simpler to
manufacture, and more rugged than is possible with a complex optical design. This design
produces a more stable, flatter baseline and more linear response.
