Press Release Summary:
Designed for lasers with less than 1 µs pulses, PF Sensors absorb laser's energy in volume of material being used. Units make use of spray deposited on surface rather than typical glass or ceramic substrate. Since absorbers consist of layer and not solid surface, units handle up to 20 x power density and offer response times of 1 s. Four models are available for various continuous and intermittent powers.
Original Press Release:
Ophir Photonics Introduces New PF Laser Sensors, Volume Absorbers with 20X the Power Handling Capacity
Logan, UT - Ophir Photonics Group, the global leader in precision laser measurement, today announced a new line of high damage threshold power volume absorbers for short pulsed lasers (<1us). The PF Sensors absorb a laser's energy in the volume of the material being used. The sensors make use of a spray deposited on the surface, not the typical glass or ceramic substrate. This means the PF Sensors provide significantly higher power handling capacity and faster response times. They can handle up to 20x the power density, up to 3KW/cm2, and the response rate time is as fast as 1s.
The PF Absorber Sensors include four models:
The PF Sensors allow power densities up to 3KW/cm2 instead of the usual 50W/cm2. The sprayed on coating is more durable, less expensive, and can be produced in any size needed. Because the absorber is a layer and not a solid surface, response times are faster.
"Until now, laser energy absorbers used solid glass or ceramic surfaces bonded to the sensor," stated Ephraim Greenfield, CTO, Photonics Group. "These were hampered by slow response times, low average powers, and limited sizes. The PF Absorbers use an absorbing layer and therefore can withstand much higher peak powers without sustaining thermal damage."
Pricing and Availability
The new PF Volume Absorber Sensors are available now. OEM pricing is available on request.
