Heat dissipation sensors feature pins for cooling
Ophir-Spiricon
Thermal laser power sensors
Ophir-Spiricon has announced a line of thermal laser power sensors with powers up to 400W.
The heat dissipation sensors feature an array of pins for cooling, unlike other devices which rely on flat cooling fins that take up more space.
This makes the Ophir-Spiricon sensors a compact and modular solution that can be tailored for a variety of OEM applications.
The sensors also feature improved detectors for better uniformity and longer lifetimes.
The thermal laser power sensors are very linear and show no drift in readings when they heat up under laser irradiation.
Linearity and stability with heating is better than one per cent in most cases, according to Ophir-Spiricon.
The devices also have high uniformity of reading over the surface, better than +/-1 per cent, in most cases.
The low-medium power thermal sensors are designed for concentrated beams and pulses with power levels from 50mW to 150W and apertures to 35mm.
The medium-high power sensors are designed for higher-power applications up to 400W and apertures to 50mm.
