6.11 Measurement of Level Fluctuations in Single-

Wavelength Light (0 nm Sweeping)

Procedure

This function measures changes over time in the level of a specific wavelength level. It is

useful for purposes such as optical axis alignment when connecting an optical fiber to a

light source. The following discussion pertains to an example in which the spatial light of

an He-Ne gas laser (1523.488 nm) is input to an optical fiber.

Setting the Center Wavelength to 1523.488 nm

Press
