The technical material below is retained for this model only. Do not transfer a range, pulse, interface, mechanical or safety value from another 1064 nm product.
Specifications
The tables below retain the supplied model record except for entries explicitly withheld after a comparison with the current model PDF. A value, option or condition from another model is not interchangeable. General explanations are separated from model-specific entries.
Source-review note
The source has an incomplete energy unit, time units under a frequency label, differing capability statements and conflicting shock-waveform labels. No missing unit, conversion or qualification outcome is inferred.
