Datasheet

Ophir-Spiricon announced 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% in most cases. The devices also
have very high uniformity of reading over the surface, better than ±1%, in most cases.

The thermal laser power sensors are produced with a new manufacturing
process that allows the devices' disks to stand up to higher temperatures,
stated Ephraim Greenfield, VP Engineering, Laser Measurement Group,
Ophir-Spiricon. This means they are more reliable under continued use and
when cycling at high powers. And because of their superior cooling capacity,
the devices are half the volume of competitive products for the same maximum
power levels.

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.
