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 4 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: 1~100 mW
- • Output / average power: 1~500 mW
- • Output / average power: 500~1300 mW
- • Operating mode: CW
- • Power stability (rms, 4 hours ± 3°C): <2%, <1%, <0.5%
Beam-quality tolerance context
Nearby series records state Beam divergence, full angle (mrad): <1.0 and Beam divergence, full angle (mrad): <2.5×0.2. These are series context, not guaranteed values for H-420; confirm them on the order-specific datasheet.
Optical integration schematic
