Centronic launches calibration service for filters and photodiodes

The electro-optics division of Centronic Inc. (Newbury Park, CA) now offers calibration of optical filters and photodiodes. The service is expected to be especially useful to companies without the resources to maintain their own calibration instrumentation. The company uses an Acton Research Corp. (Acton, MA) triple grating monochromator equipped with a radiometrically calibrated tungsten and deuterium light source. Calibration results are traceable to NIST standards, with an accuracy of ۭ%

Centronic launches calibration service for filters and photodiodes

The electro-optics division of Centronic Inc. (Newbury Park, CA) now offers calibration of optical filters and photodiodes. The service is expected to be especially useful to companies without the resources to maintain their own calibration instrumentation. The company uses an Acton Research Corp. (Acton, MA) triple grating monochromator equipped with a radiometrically calibrated tungsten and deuterium light source. Calibration results are traceable to NIST standards, with an accuracy of ۭ% for the wavelength range of 400-1200 nm and ۲% for wavelengths shorter than 400 nm. Types of calibration include optical filter transmission, reflection, and blockage, as well as photodiode responsivity in A/W and V/W.

Centronic is a manufacturer of stock and custom silicon photodiodes. It has supplied photodiodes for the Polar Ozone & Aerosol Measurement (POAM II) instrument, a spectral photo meter commissioned by the Naval Research Agency to record changes in the polar ozone layer.
