AQ6374

Optical Spectrum Analyzer by Yokogawa Electric Corporation

Note: Your Quotation Request will be directed to Yokogawa Electric Corporation.

The AQ6374 from Yokogawa Meters & Instruments is an Optical Spectrum Analyzer that can evaluate both visible and optical communications wavelengths from 350 to 1750 nm. It has a wide dynamic range of 60 dB and high wavelength resolution of 0.05 to 10 nm. With a maximum resolution of 2 pm and the ability to sample power levels at up to 100,000 wavelength points, the analyzer can precisely evaluate and analyze a wide range of wavelengths with a single scan. The AQ6374 can be used to develop distributed semiconductor devices such as feedback laser diodes (DFB-LD) that emit only one wavelength as well as optical fibers that necessitate measurements over a wide range of wavelengths.

The AQ6374 comes with two additional enhancements. The first is a function that purges the water vapor trapped in its monochromator that can suppress the absorption of light at certain wavelengths. The second is a function that reduces the effect of high-order diffracted light whose wavelengths are 2–3 times that of incident light, a characteristic that all monochromators have due to their design principle. It is ideal for emission spectrum measurement for semiconductor & fiber lasers and measurement of wavelength transmission characteristics for optical fiber & optical filters.
