Laser spectrum Analyser - LSA
Absolute accuracy: 6000 MHz, resulution: 1000 MHz
Sensitivity: 5 nJ @ 633 nm
Low stage spectral resolution: (&lambda/&Delta&lambdaFWHM): 1000
High stage spectral resolution (&lambda/&Delta&lambdaFWHM): 30000 (SM fiber),     10000 (50µm fiber)
max. spectral range: 2nm @ 350nm, 7nm @ 600nm, 25nm @ 1064nm
linewidth accuracy : 10%
    (min. linewidth &delta&lambda/&lambda= 2*10-5 (e.g. 10pm @ 633nm))
    (max. linewidth: half of max. spectral range)
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.
