📏 Laser Distance Meter for Fiber Lasers – precise, smart & extremely practical! 🔥🤖

Since constantly measuring with a tape measure on the fiber laser annoyed me, I designed and built a digital distance meter to the base plate
Precisely because different lenses have different focal points, you often have to readjust – and this is exactly where this tool plays to its strengths

👉 The device directly measures the distance from the lens to the base plate
👉 This allows the exact focal point to be noted
👉 No tape measure, no more fumbling
