Laser spectrum Analyser - LSA

Absolute accuracy: 6000 MHz, resulution: 1000 MHz

 Sensitivity: 5 nJ @ 633 nm
 Low stage spectral resolution: (&lambda/&Delta&lambdaFWHM): 500
 High stage spectral resolution (&lambda/&Delta&lambdaFWHM): 20000 (SM fiber),
    10000 (50µm fiber)
 max. spectral range: 3 THz
 linewidth accuracy : 10%
    (min. linewidth &delta&lambda/&lambda= 2*10-5 (e.g. 10pm @ 633nm))
    (max. linewidth: 1.5 THz
 Built-in light source for autocalibration

The LSA is designed to analyse the multi-line or broadband spectrum of lighte sources like cw and pulsed lasers, gas discharge lamps, super luminescence diods, semiconductor laser diodes and LEDs.

(b) Values for wide-/fine-mode   (g) according 3&sigma criteria
(11) The cw power interpretation in [µW] compares to an exposure of 1 s.
       For other exposures, the energy needs to be divided by the exposure time to get the power.
