Dimensions are the published body envelope. They exclude the harness, the connector, and any bracket. Clearance around the emitting face is a separate requirement.
What the numbers mean in practice
Two things scale with the package, and both change the mechanical design rather than just the drawing. First, the mounting interface: a 2.5 g microchip can be held by its own leads, while a 220 g block needs a machined face and defined fasteners so the optical alignment is not carried by the housing. Second, the thermal path: waste heat leaves through the mounting face on every model, so the heavier units expect a flat, thermally conductive interface, not point contact on a painted bracket.
Before you design the mount
- Use the outline drawing, not the table above, for the datum and fastener positions.
- Ask for the STEP model when the bracket has to clear the optics — the drawing shows the body, not the beam path.
- Leave room for the harness bend radius; on the compact models the cable is heavier than the source.
- Check the beam height against the receiver aperture before fixing the mount; a 1 mm offset at the source becomes a large miss at range.
- Decide the thermal interface material now, not after the first thermal cycle shows drift.
Alignment after assembly
Boresight has to be adjustable and lockable. The source is rigid, but the bracket and the window are not, and a 10 K change is enough to move a light mount. Measure boresight at a known distance after the first thermal cycle, not only at assembly.

Which package for which requirement
The smallest outline in the range is the compact family (14.5–40 mm, 2.5–18 g). If the constraint is update rate rather than size, the high repetition models share a 6 g package; if it is energy, the rangefinder and LiDAR pages cover the larger transmitters: rangefinders, LiDAR.
