This guide covers when to calibrate, what calibration actually involves, what a legitimate certificate looks like, and how to verify your meter's accuracy between calibrations. Send the meter to a NIST-traceable calibration lab. This application note demystifies how EXFO's IQS-12002 Optical Calibration System can guide. Spectral test stations used to characterize photonic components rely on optical paths composed of tunable lasers, switches, fibers, connectors, and power meters. Each element introduces wavelength-dependent loss, ripple, and drift that distort measured spectra and obscure true device. NIST has established measurement services for the calibration of optical fiber power meters at the three nominal wavelengths of 850, 1300, and 1550 nm using either collimated beam or optical fiber/connector configurations. If we find a performance problem with the received instrument, we will let you know. You can also ask for a linearity. Micro Precision Calibration provides ISO/IEC 17025 accredited services for a wide range of optical test equipment.
