Laser Calibration Services
As well as re-calibrations of our own instruments, we offer a wide range of Calibration Services for instruments which measure CW laser power, pulsed laser energy, pulsed peak power, peak power density etc. Both CW and pulsed calibrations are offered. We can normally match your wavelength exactly for CW calibrations and fairly closely for pulsed calibrations. We also do some electronics calibrations (such as fast amplifiers) and optics (such as Autocollimators and safety goggles).
For most Calibrations the turn round time is usually 3 to 5 days .
The list below gives a sample of our standard capabilities. We also do many special calibrations, so please enquire if the exact service you need is not listed.

Certification
Each Certificate gives details of:
- The calibration method and precautions taken.
- The absolute accuracy and traceability of the calibration. Typically this is between ± 1.5% and ± 3.5% depending on the number of stages. The traceability is to the UK National Physical Laboratory whose standards of CW Power and Pulsed Laser Energy we use.
- Comments on the relevance of the calibration to the intended use of the Instrument. For example a calibration might be done at low power CW when the end use is at high pulsed power; in this case we would estimate the possible extra errors in changing the power level.
- Expiry of calibration. Taking into account the type and design of Instrument, we suggest a sensible period for this particular calibration to remain valid (given normal Laboratory conditions and normal care).
