Series-level technical context
Engineering context for a thin CW Lasers record
This model has no standalone PDF and only a small number of model-specific rows. The values below are traceable context from 2 nearby configurations on the same source-product record; they define the parameters to qualify, but are not substituted for an order-specific datasheet.
Typical operating fields in the series
- • Output / average power: 1~400 mW
- • Output / average power: 1~360 mW
- • Operating mode: CW
- • Power stability (rms, 4 hours±3℃): <3%, <2%, (<1% optional@Water Cooled)
Beam-quality tolerance context
Nearby series records state M²: ~3.0 and Beam divergence (mrad): <3.0. These are series context, not guaranteed values for FC-491; confirm them on the order-specific datasheet.
