## Restrictions

This product incorporates a laser system. Before purchasing or using laser equipment (including modules, components, or complete machines such as laser cutters and engravers), please consider the following:

- These products are intended for professional, educational, industrial, or supervised workshop environments.
- Operators should be appropriately trained and understand laser safety practices, including enclosures, signage, PPE, and safe operating procedures where applicable.

A declaration of use will need to be submitted during checkout.

## Description

The laser transmitter emits laser light at time t1. The laser collector collects the reflected laser distance at time t2 = (t2-t1)\*light speed/2, because t2-t1 is the round-trip time from laser emission to reception.
