Measuring Instruments Quality Control at the Highest Standard
-thorough inspection, advanced metrology, and expert review for measuring instruments that perform with confidence.
Calibration and measuring instruments quality assurance (QC) are fundamental to the performance, reliability, and accuracy of every instrument we manufacture. Each device undergoes rigorous testing and verification before shipment.
Our commitment to measurement accuracy ensures that researchers, engineers, manufacturers, and quality assurance teams receive instruments that deliver dependable results throughout their operational lifetime.
State-of-the-Art Calibration Equipment
To maintain the highest standards of measurement accuracy, Artifex Engineering performs calibration using industry-leading test and measurement equipment, including:
- Tektronix high-performance digital oscilloscopes
- Keithley DM6500 6½-digit precision multimeters
- Stanford Research Systems (SRS) precision current sources
- Stanford Research Systems (SRS) precision voltage sources
These instruments provide exceptional measurement resolution, stability, and traceability, enabling us to verify electrical and optical performance parameters with a high degree of confidence.
By utilizing modern calibration equipment and documented quality procedures, we ensure that every measurement channel, amplifier stage, and sensing circuit performs within specification.

Calibration of LIV100 and LIV120 Systems
The LIV100 and LIV120 systems are designed for precise laser diode characterization and testing. During production and final inspection, each system undergoes comprehensive verification of:
- Current source accuracy
- Voltage measurement accuracy
- Optical power measurement performance
- Data acquisition integrity
- System linearity and repeatability
- Communication and software functionality
These calibration procedures ensure that laser diode LIV measurements are accurate, repeatable, and suitable for both research and production environments.
Quality Control for the TZA500 Transimpedance Amplifier
The TZA500 Transimpedance Amplifier is designed for high-speed, low-noise photodiode signal amplification. To guarantee performance, each unit is subjected to extensive quality control testing, including:
- Gain verification
- Bandwidth validation
- Noise performance evaluation
- Offset and linearity measurements
- Stability and functionality testing
Using precision current sources and advanced oscilloscope measurements, we verify that every amplifier meets its published specifications before delivery.

Calibration of the OPM150 Optical Power Meter
Accurate optical power measurement is critical in photonics, telecommunications, laser research, and manufacturing applications.
Each OPM150 Optical Power Meter undergoes calibration and verification procedures that assess:
- Optical power measurement accuracy
- Detector response consistency
- Signal conditioning performance
- Electronic measurement integrity
- Overall system stability
This process helps ensure reliable optical power measurements across the instrument’s operating range.

Why Calibration Matters
Regular calibration and strict quality control provide several important benefits:
- Improved measurement accuracy
- Enhanced repeatability and consistency
- Reduced uncertainty in test results
- Increased confidence in research and production data
- Long-term instrument reliability
- Compliance with quality management procedures
For laboratories, universities, OEMs, and manufacturing facilities, reliable calibration is essential for maintaining confidence in critical measurement systems.
