The sensors which now feature the improved LP1 absorber include:
– L300W-LP1-50, high power water-cooled thermal sensor for 4W – 300W, 50mm aperture
– FL400A-LP1-50, medium-high power fan-cooled thermal sensor for 300mW – 400W, 50mm aperture
– 1000W-LP1-34, high power water-cooled thermal sensor for 5W – 1000W, 34mm aperture
– L1500W-LP1-50, high power water-cooled thermal sensor for 15W – 1500W, 50mm aperture
“The LP1 absorber coating provides Ophir’s high power laser sensors with the highest damage thresholds in the industry,” commented Ephraim Greenfield, CTO, Ophir Photonics. “Traditional surface absorbers have a much lower damage threshold at >1000W. They can damage at 2-3 kW/cm2. We have developed a denser coating that has higher heat resistance, thus improving the damage threshold for our high power lasers. The LP1 coating also has a much higher damage threshold for long pulses reaching power damage thresholds of over 200 J/cm2 for 10 ms pulses.”
