Frequently Asked Questions about Laser Doppler Vibrometer

When the detection distance of the LV-1710/LV-1720(A) is set to the shortest possible distance (100 mm) and the laser beam is focused, the spot diameter of the laser beam will be approximately φ 20 μm.

As the detection distance increases beyond 100 mm, the diameter of the focused laser beam spot increases proportionally to the distance.
