Optical Power Meter Head Special Calibration

Introduction

The test and measurement equipment you select and maintain in your production and qualification setups is one of the most important parts of ensuring the quality, reliability and performance of your end product. The specified accuracy of your instrument, which gives you confidence in the measurements they produce, can only be analyzed and certified by proper calibration. Calibration of your test and measurement equipment ensures that you can trust your measurement results and have confidence in your own precision.

Furthermore nearly all existing quality assurance standards, norms and procedures such as ISO/IEC 9001 or ISO/IEC 17025 require a periodic quality assessment for your test and measurement equipment. Following these standards requires you to regularly monitor your instruments by performing calibrations.

Optical power meters are designed to measure optical power in a specified wavelength range as accurately as possible. Due to the fact that this capability largely depends on the quality of the calibration process, it is important to carefully select your calibration provider.

Keysight Technologies, as the original equipment manufacturer for several types of optical power meters, is able to verify all specified parameters and to perform adjustments that bring out-of-specification instruments back into specification. In this way you can receive calibration services for your optical power meters that meet or even exceed your expectations on level of quality for your test and measurement systems and your end products.

With the special calibration options C01, C85 and C05 Keysight offers calibration services for its optical power meter heads for lowest measurement uncertainties as metrology grade reference standards.

Keysight’s Optical Power Meter Heads

As an industry leader in optical power measurements, Keysight’s offers a number of superior solutions that guarantee highest performance for your various applications. The 81623B, 81624B and 81626B optical power meter heads provide a 5 mm diameter photodetector area. The simple geometry and high quality detectors allows the heads to offer the highest accuracy measurements. Various connector interfaces for popular fiber connector types or bare fibers can be plugged to the front panel optical input.

The optical power meter heads feature firmware-correction of range discontinuities for best linearity, variable averaging time, data logging, and min-max and stability applications. The detectors of the optical power meter heads are temperature stabilized. The spectral responsivi­ty data (Figure 1) is stored in the head, in steps of 2 nm.

Special Calibration Options

Calibration Options C01 and C85

Keysight’s optical power meter heads, 81623B, 81624B and 81626B, are highly precise tools to accurately measure optical power. The accuracy of these versatile instruments can be further increased by an additional detector selection and special calibration performed in the factory’s Optical Metrology Laboratory. The result is an optical power meter head that is calibrated with lowest measurement uncertainties and has tighter specifications. The specially calibrated optical power meters are most attractive for high accuracy calibration purposes.

The calibration options include the following package of measurements:

- Responsivity versus wavelength

- Linearity over the specified measurement range

- Spatial homogeneity over the detector’s active area
