The Short Range Straightness Measurement Optics Kit allows the measurement of horizontal straightness error in linear axes up to 4 m in length to be made. They also enable axis parallelism to be measured.

Each short range straightness kit contains:

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

• 1 straightness reflector

Specifications:

Axial range 0.1 m – 4 m (4 in – 160 in)

Straightness measurement range ±2.5 mm (±0.1 in)

Accuracy ±0.5% ±0.5 ±0.15M2 µm (±0.5% ±20 ±0.5F2 µin)

Resolution 0.01 µm (1 µin)

Where:

% = percentage of displayed value

M = measuring distance in meters

F = measuring distance in feet
