Retro Reflection Probes
|
StellarNet
Inc. offers a low-cost, rugged, high-throughput retro-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 3000 psi. This
outstanding performance is achieved by using Kalrez®
O-ring seals. The retro-reflection probe is available in fixed path lengths
of 2, 5, 10, 20 and 50 mm. 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.
The retro-reflection probe is available in both UV and NIR versions, as
dictated by the customer's application needs.
TECHNOLOGICAL INNOVATIONS
The
retro-reflection probe incorporates a back reflecting aluminum mirror for
high light return in the UV region. Using this design, the sensitive
aluminum layer is back-coated on a silica disk with a protective MgF2
overcoat. The mirror is then sealed into the bottom of the probe. Both
the mirror and the collimating lens are held in the stainless steel housing
with Kalrez® O-rings. All
wetted surfaces are silica, stainless steel or Kalrez®.
For more demanding applications,
the optical surfaces may be over coated with diamond-like carbon film.*
This film improves corrosion resistance and reduces fouling.
* Visible and NIR use only.
