Frequently asked questions

Answers to the most common questions about our products and services

These versions project a short line for distance measurement on challenging surfaces such as shiny or textured metals. Select the LL platform for the application.

No. LL is an optical variant used across several series. Span, rate and linearity depend on the exact model, not the suffix alone.

No. The table distinguishes start, middle and end. State both spot/line dimensions and the specified working position.

Certain models do. Bracketed spans apply at 49.14 kHz. Check required working coverage against that rate-specific window.

No. Its linearity has specified target conditions. Suitability for challenging surfaces does not remove material, reflectance and angle checks.
