Thorlabs C-Series Integrating Sphere Power Sensor Calibration Services

Simbol Test Systems provides professional in-lab Thorlabs C-Series integrating sphere power sensor calibration services to help maintain accurate, reliable performance for your laser and optical test equipment. The Thorlabs C-Series includes specialized integrating sphere sensors designed to measure laser power with minimal sensitivity to beam shape, divergence, entrance angle, or beam uniformity.

Using an internal high-reflectance integrating sphere, these sensors diffuse and depolarize incoming light before detection, making them well suited for diverging free-space beams and high-numerical-aperture optical fibers. The series includes multiple detector and wavelength configurations, including models such as S140C, S142C, S142CL, S144C, S145C, S145CL, S146C, S148C, and S180C.

These sensors are widely used for laser power measurement in laboratory and photonics environments where beam geometry and entrance angle can affect standard detector readings. All calibration services are performed in our laboratory using documented procedures, traceable standards, and experienced technical staff.

Following calibration, your equipment may be returned with a calibration label, calibration certificate, and related calibration data.

Traceability: Instrumentation used during this calibration is traceable to N.I.S.T. (National Institute of Standards and Technology) or C.N.R.C. (Canadian National Research Council), where applicable.
