High Resolution Optical Spectrum Analyzers
 |
|
AP2050A : C band, 20 MHz resolution |
|
The APEX Technologies Optical Spectrum Analyzers clearly show much more details than the grating based OSA and leaves any kind of guess work behind. Based on an interferometric principle. APEX Technologies high resolution optical spectrum analyzer can achive a 248 times better resolution than monochromator based optical spectrum analyzer. |

High Resolution |
|
APEX Technologies OSA rectangular shape filters (20 MHz/0.16 pm) allow a nearly perfect integration of the signal over the selected resolution (ajustable from 2 THz/16 nm to 180 MHz/1.44 pm), while a grating based OSA filter integrates...more (pictures,videos)

Close-in Dynamic Range |
|
The resolution bandwidth of an APEX Technologies OSA isn't related to optical filters, but electrical filters close to rectangular shape. Thanks to these specia:...more (pictures,videos)

The two different internal wavelength calibrators (absolute and relative) allow the equipment to provide an excellent wavelength accuracy specification of +/- 3 pm. The absolute wavelength calibrator is a gas cell with fixed absorption peaks used as reference. The relative one is a Fabry Perot with a fixed free spectral range used as reference. |
