What this model is for
- Integrating a 1535 nm transmitter into your own rangefinder or designator, where you supply the receiver, timing electronics and optics.
- Pulse-energy budgets where the erbium-glass source drives a fibre or free-space transmitter chain and the surrounding system owns the safety case.
- Lab, range and OEM builds that need a repeatable 1535 nm pulse rather than a finished instrument.
Integration notes
ER400 is a bare module, not a finished instrument: it arrives with an electrical interface and a mechanical envelope, and your product owns the optics, the housing and the safety case. The documented interface is see datasheet and the documented supply is see datasheet. Where a figure above is a limit (≤ / ≥), treat it as the manufacturer's statement and confirm the acceptance test in your own build rather than assuming margin.
For a 1535 nm source, the laser safety classification of the finished product is the integrator's responsibility: the module document states its own classification, and the accessible emission of your assembled unit must be assessed separately.
