LASER DIAGNOSTICS

 

Ophir Photonics Group began making laser power meters, energy meters, and beam profilers in 1979.  There are many headquarters around,  in the United States, Israel, Japan, and Germany, as well as distributors in over 50 countries worldwide. We at Kimmy Photonics are proud of being a part of this family!


If you want to get the most out of your laser – most power, most efficiency, most safety – you need to measure it. And the more accurate your measurement, the closer you can come to perfection in your laser. Let us help you with the right solution!

Laser Power Meters

Laser Power and Energy Meters

 

Ophir laser power meters work on the smart plug principle. This means that almost any Ophir power meter can work – plug and play – with almost any of the wide range of Ophir sensors. Ophir power meters are also the most precisely calibrated units on the market thus measuring with the highest accuracy. As for ease of use, Ophir laser power meters have the most user friendly interface. The meters also come with a versatile and easy-to-use software for use either stand-alone or interfaced with LabVIEW or the users's own software.

PC Interfaces

 

Ophir PC interfaces work on the smart plug principle. This means that almost any Ophir PC interface can work – plug and play – with almost any of the wide range of Ophir sensors. Ophir PC interfaces are also the most precisely calibration units on the market thus measuring with the highest accuracy. With the versatile Ophir StarLab software, your PC becomes a complete laser measurement station. Ophir also provides software to interface seamlessly with LabVIEW or the user's own software.

Laser Beam
Profilers

Camera-based beam profilers

 

A camera-based beam profiler system consists of a camera, profiler software and a beam attenuation accessory. Spiricon offers the broadest range of cameras in the market to cope with wavelengths from 13nm, extreme UV, to 3000 μm, in the long infrared. Both USB and FireWire interfaces are available for most wavelength ranges providing flexibility for either laptop or desktop computers.

Scanning-Slit Based Profilers

 

The scanning slit beam profiler moves two narrow orthogonal slits in front of a linear photo-detector through the beam under analysis. Light passing through the slit induces a current in the detector. Thus, as the slit scans through the beam, the detector signal is linearly proportional to the spatial beam irradiance profile integrated along the slit. A digital encoder provides accurate slit position. The photo-induced current signal is digitized and analyzed to obtain the beam profile in both X and Y from the two orthogonal slits.

Sensors

Laser Power Sensors

 

Ophir provides two types of power sensors: Photodiode sensors and Thermal sensors. Photodiode sensors are used for low powers from picowatts up to hundreds of milliwatts and as high as 3W. Thermal sensors are for use from fractions of a milliwatt up to tens of thousands of watts.
Thermal sensors can also measure single shot energy at pulse rates not exceeding one pulse every ~5s.

Laser Energy Sensors

 

Ophir has two types of energy sensors, pyroelectric and photodiode. Pyroelectric sensors are for measuring repetitive pulse energies and average powers at pulse rates up to 25000 pulses per second and pulse widths up to 20 ms. Photodiode energy sensors are for very low energy pulsed lasers, as low as 200 pJ. Note that single shot energy with pulse rates less than one pulse every 5 s or so can be measured with thermal sensors.

BeamTrack - Power/Position/Size Thermal Sensors 100µW - 1000W

 

Thermal sensors that measure laser power and single shot energy like standard thermal sensors but in addition measure laser beam position and laser size. This position sensing detector measures laser beam position to 0.1mm accuracy and laser size measurement of a Gaussian beam to +/-5% accuracy. Measuring laser position is important for laser alignment where the laser position sensor can provide feedback to the laser position control.
