Ophir Photonics Introduces Fast Axial Thermal Laser Sensors for OEMs;
Fast Response Time, Over 2000J Pulse Energy
Fast Axial OEM Sensor
October 31, 2012
October 31, 2012 — North Logan, UT– Ophir Photonics Group, the global leader in precision laser
measurement equipment and a Newport Corporation brand, today announced the Fast Axial OEM
Sensor. The sensor is based on a novel thermopile design
that provides significantly faster response times
and higher power levels. Response times are up to 20
times that of traditional thermopile sensors; power and
energy levels are up to 2000J for single pulses and
over 20KW average power. The Fast Axial OEM Sensor
is designed to handle a wide array of laser beam
sizes, from 20mm to 180x180mm.
The Fast Axial OEM Sensor operates on the
principle of axial heat flow in the direction of incident
laser or light beams. This is instead of the usual radial
flow sensor where heat flows from the center outwards. In the Axial Sensor,
heat flows through a thermopile deposited as a thin layer on the surface
of the heat sink. Heat flows only a small distance axially into the substrate. This results in
significant improvements in response times and support for higher power levels."
“Ophir offers OEM sensors for any type and wavelength of laser, for any power or configuration,”
said GaryWagner, General Manager, Ophir Photonics (U.S.). “The Fast Axial OEM
Sensor is based on a unique design that delivers response times up to 20 times better than the
best radial thermopile sensors, reaching 10-90% response time in 50ms. The novel design allows
the sensor to be configured to support very large beams, up to 180x180mm capable of measuring
over 2000J per pulse. The sensor can also handle high powers. The 180x180mm configuration
can handle over 20kW of average power.
High speed, small aperture versions of the Fast Axial OEM Sensor can be used as internal
monitors of high power industrial lasers; the fast response time means better control of laser
power. The smaller version can measure up to 150W.
Availability & Pricing
The Fast Axial OEM Sensor is available now for custom configuration. OEM pricing on request.
