ER / MINI series — 1535 nm erbium-glass laser sources
Transmitters for integrators who build their own rangefinder or designator: 100 µJ to millijoule class, 4 to 10 mrad raw divergence, 2.5 to 220 g, with the receiver and timing electronics supplied by your design.

What this family is, in integration terms
A rangefinder module is a component: it provides a laser channel, a receiver and a data interface, and your product supplies the optics, the housing and the safety case. Mass and interface decide whether it fits, and both are in the table above.
- Reflectance appears twice in a datasheet. Where a sensor publishes 90 % and 10 % columns, the 10 % column is the real-world number — an AGV looks at a matte surface, not a retro-reflector.
- Update rate is not accuracy. 200 Hz with centimetre resolution is a good control input and a poor measuring instrument; decide which you are building.
- Ambient-light immunity (published in klx on several of these) decides outdoor usability far more than the headline range does.
Choosing inside this series
Range, mass and interface move together here: the longest-reach parts are the heaviest and run RS-422, while the lightest parts are short-range and run UART-TTL. Pick the two you cannot negotiate, then read the model page for the test condition behind the range figure — a 12-model series usually quotes several different targets.
