How to tell a guaranteed limit from a typical figure, what the environmental claims are based on, and the questions worth asking of any supplier datasheet.

Why 1064 nm Nd:YAG and 1535 nm Er:Yb glass are different tools, what ytterbium co-doping does, and an honest account of where Nd:YAG still wins.

What the driver must supply, why drive pulse width is not optical pulse width, and how to arrange the thermal path. With the published limits for every model.

How pulse repetition rate, platform speed and scan geometry set LiDAR point density, worked through with published figures, and why one beam is not enough.

How pulse width sets the closest two targets a rangefinder can separate, with the published figures for every model and what a shorter pulse costs elsewhere.

Why 1535 nm is eye-safe and 905 nm is not, what that allows in pulse energy within Class 1, and where each wavelength still wins. The mechanism explained.

How pulse energy, target reflectance and receiver sensitivity combine in a rangefinder link budget, and where each energy tier fits. Published specifications.

ERDI TECH exhibited at the 2026 Shenzhen photonics exhibition (COIE) from 9 to 11 September at booths 8C01/8C02 in Hall 8, meeting OEM teams, integrators and distributors on 1535 nm eye-safe laser rangefinder modules, laser target designators and erbium glass laser sources.

The SPD1200N2 combines a 0.2 m minimum range, ±0.3 m accuracy through 100 m, a 7.2 × 14.7 × 21.3 mm nominal body, and a mass of 5 g or less for compact civilian OEM ranging systems.
