Why should you use BS EN 62522 - Calibration of tunable laser sources?
Laser stands for Light Amplification by the Stimulated Emission of Radiation. The laser emits a mixture of visible and invisible light waves. These waves produce different types of light such as ultraviolet, blue, green, and red which can be harmful to you. As laser products improve the quality, precision, and accuracy, of many products but to realize the benefit, the risk of laser exposure must be managed.
BS EN 62522 discusses terms, definitions and abbreviations that depict a user-friendly idea of tunable laser sources. BS EN 62522 also provides users with wavelength calibration and optical power calibration which contributes to the performance characteristics of tunable laser sources ensuring their reliability. The guidelines in BS EN 62522 help you assess the calibration of tunable laser sources that enables you to provide a superior quality product to your customers.
