PM10K+ & PM15K+ Laser Power Sensors
The PowerMax kW sensor line now offers three water-cooled, large-area options for measuring up to 20kW in under 5 seconds:
PM10K+ (10 kW), PM10K+ with Backscatter Shield (10 kW with 99 % back-reflection capture), and the larger PM15K+ (15 kW / 20 kW intermittent). All use our broadband BB+ absorber (190 nm – 11 µm), include safety interlock, and connect via USB/DB-25 or RS-232 for drop-in integration.
Key Specifications
• Continuous power: 10 kW (PM10K+), 10 kW + backscatter capture (Shield), 15 kW (PM15K+); intermittent to 12 kW / 20 kW.
• Active area: 65 × 65 mm (PM10K+) or 100 × 100 mm (PM15K+).
• Broadband 0.19 – 11 µm BB+ coating.
• 3- to 5-second measurement; water-cooling with temp/flow interlock.
• Interfaces: DB-25 + USB or RS-232; dovetail mount included.
