NML Labs

The research scope of the Electrical/Electromagnetic Measurement Laboratory (EEML) covers electricity, magnetism, and microwave. It has established standards in the three fields to provide traceability for domestic industry.  

In the area of electricity, the established systems in voltage and current provide complete calibration services to the local industry, including a variety of range from electrical power, electrical energy, phase angle, resistance to inductance, and capacitance. To meet the requirements from the semiconductor industry, the EML has established Sheet Resistance Measuring System in order to provide the calibration for semiconductor reference materials.

The Dimensional Measurement Laboratory (DML) provides traceability of dimensional standards and calibration services for domestic industry. A variety of measurement systems were established and categorized as end standards, scales, angles, topography, thickness and so forth. The provided calibration services include stabilized laser frequency, long and short gauge blocks, ring gauges, plug gauges, line scales, polygons, index tables, roundness, roughness, step height, standard tapes, theodolites, electronic distance measuring instruments, interferometers, gratings, line width, , GPS receivers, etc. In addition to the developments of calibration systems, the DML also devotes into advanced dimensional metrology research such as optical frequency standard of femtosecond laser, and geodetic measurement standards.

The research scope of the Dynamic Engineering Measurement Laboratory (DEML) mainly covers in the fields of vibration, acoustics and ultrasound metrology.

Vibration measurement has a wide range of applications. In additional to the calibration capability of accelerometers, charge amplifier and vibration meters, the DEML is also well equipped with the modal analysis for structural vibrations and enhancement techniques, the experimental analysis and control techniques of floor vibrations for factory buildings, and the monitoring, analysis and preventing techniques of environmental vibrations, and rotor rotating unbalanced and roundout measurement of rotor under spinning test. Also the DEML serves the monitoring and fault diagnostics of mechanical equipments, performance verification of vibration isolators, precision measurement of floor vibrations, etc.. Furthermore, the advanced technology in non-contact precision measurement is under developing at the moment.

The Optical Radiation Measurement Laboratory (ORML) has established several measurement standards. The established systems provide complete calibration services to the local industry, including a range from illumination, total luminance flux, spectoradiometry, colorimetry, absolute radiometry, to transmittance, and reflection.

In addition to calibration systems, the measurement techonologies for flat panel displays (FPDs) and light-emitting diodes (LEDs) are established to provide measurement services for the industrial demands.

The Nano and Mechanical Measurement Laboratory (NMML) has established the standards in the fields of mass, force, pressure,vacuum and nano. For the mass standards, a primary mass standard, Pt-Ir kilogram prototype, has been set up to provide the weight traceability. In the region of force, the calibration services are available for several types of force transducers. In the region of vacuum, the calibration services are developed for varieties of vacuum gages. In the region of pressure, a mercury manometer system has been established for different types of pressure calibration. In the region of nano, measurement systems for nanoparticle sizes have been established for different types and sizes of nanoparticle size calibration. In the region of thin films, measurement systems for thin film thickness and mechanical properties have been established to calibrate different types and thickness of films.

The Flow and Energy Research Laboratory (FERL) has established 11 flow calibration systems for traceability of industrial flow meters. In the area of liquid flow, the laboratory has established a water flow facility. In addition, a Laser Doppler Velocimetry (LDV) system and a micro-Particle Image Velocimetry (μPIV) system are capable of providing services in flow field measurement and analysis for a wide range of length scales.

The Medical & Chemistry Research Lab (MCL) has established standards in the related medical and chemistry fields for providing calibration service to the domestic industry. The major works include the development and dissemination of certified reference materials, techniques for gas concentration verification, and Contract research & consultancy, etc. In 2012, MCL has passed the assessment of the Taiwan Accreditation Foundation (TAF) and got the certification of ISO Guide 34, which recognizes MCL as the first lab domestically for the competence of reference material producers.
