The Long Range Straightness Measurement Optics Kit can be used to measure the horizontal straightness error in linear axes from 1 m up to 30 m in length when using the XL-80 laser system. They also enable measurement for parallelism of axes.

Each long range straightness kit contains:

• 1 straightness interferometer (also referred to as a Wollaston prism)

• 1 straightness retroreflector

• 2 alignment targets

Specifications:

Axial range: 1 m – 30 m (40 in – 1200 in)

Straightness measurement range ±2.5 mm (± 0.1 in)

Accuracy* ±2.5% ±5 ±0.015M2 µm (±2.5% ±200 ±0.05F2 µin)

Resolution 0.1 µm (10 µin)

Where:

% = percentage of displayed value

M = measuring distance in meters

F = measuring distance in feet
