| 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.
