Ophir-Spiricon has introduced a new line of Thermal Laser Power Sensors with powers up to 400W. These high performance, heat dissipation sensors feature an array of pins for cooling, unlike other devices which rely on flat cooling fins that consume significantly more space. As a result, they are the most compact laser power sensors on the market, half the size of most devices. The modular design can be tailored for a variety of custom OEM applications as well.
The new high thermal efficiency sensors also have improved detectors for better uniformity and longer lifetimes. The 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 1 per cent in most cases. The devices also have very 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, apertures to 50mm.
