Gold cone absorber: Measure high-power lasers with low back reflections
The most remarkable feature of the GD absorber is that it has the highest damage thresholds for the average power density of the HP series, making it an ideal choice for small, high-power beams. It also features lower back reflections than our standard H absorber.
Customers enjoy:
- Safer work environment when working with very high-power lasers
- Kilowatt-level power measurement
- Highest average power density damage threshold
- Low risk of damaging the equipment with your laser
Use it with our included PC-Gentec-EO software
Read your measurements directly on your PC thanks to our free proprietary software PC-Gentec-EO. The software supports the following product series: P-LINK, HP, INTEGRA, U-LINK, and MAESTRO.
Enjoy:
- Practical displays: real-time, scope, needle, averaging, histogram, and statistics
- Useful features such as data logging and correction factors
- Many statistics available: current value, average value, maximum value, minimum value, RMS stability, PTP stability, repetition rate, average power, and STD deviation
Faster measurement with XNR AnticipationTM
Measure laser power up to 10x faster (model-dependant) with XNR AnticipationTM. Our proprietary algorithm looks at the rate at which the signal increases or decreases and combines this with calibration data to predict the result. The measurement is therefore calculated and displayed faster than the natural response of the detector.
Why does it matter?
- Save several seconds to tens of seconds for each measurement
- Shorter operation interruption
- Faster laser output diagnostics
- Increased productivity
- No compromise on measurement accuracy
NIST-TRACEABLE CALIBRATION INCLUDED
Traceable calibration provides the ability to trace the readings of laser output measurements to known international measurement standards determined by the National Institute of Standards and Technology (NIST). This ensures that the measurements taken by the instruments are reliable and accurate.
Benefits include:
- Make valid comparisons of measurements taken by other instruments inside and outside your organization and over time
- Comply with regulations or conform to industry standards
- Avoid costly measurement mistakes in your operations
- Improve customer confidence in your laser systems
- Ensure laboratory experiment validity
- Demonstrate measurement accuracy easily with the calibration certificate we provide
