Anritsu has expanded the capabilities of its MS9740B optical spectrum analyzer for testing pulsed laser diode chips throughout manufacturing. The measurement perform was added to fulfill the elevated manufacturing of high-power laser diode (LD) chips, pushed by increased communication bit charges and longer LiDAR detection ranges.
By eliminating the necessity for a set off sign, the MS9740B analyzer accelerates the optical spectrum analysis of LD chips. The expanded functionality of the MS9740B additionally ensures measurement reproducibility of ±1.4 dB for side-mode suppression ratio (SMSR). Low SMSR variation improves LD chip yield and manufacturing effectivity.Â
Meant for manufacturing environments, the MS9740B optical spectrum analyzer gives a excessive dynamic vary of as much as 70 dB (±1 nm from peak wavelength) and quick sweep speeds of <0.2 s over a wavelength vary of 600 nm to 1750 nm. Anritsu says that the MS9740B reduces measurement occasions by as a lot as half in comparison with the earlier mannequin.
