Optical Square

Product Code : JA-G-3576

The Optical Square (SKU JA-G-3576) is a surveying instrument for setting out right angles in the field, used to measure offsets from the chain line. Standing on the chain line, the surveyor sights a ranging rod along the line and an object to the side at the same moment; when the two coincide, the object lies at 90 degrees to the line. JaincoLab manufactures it for survey practicals and field geometry.

Specifications

The optical square is a hand-held surveying instrument for setting out right angles and taking offsets from a chain line; body material, size and case are not given in the listing and are confirmed on the quotation.

Applications of the optical square

In chain surveying the optical square locates the foot of the perpendicular from a feature to the chain line, so students can measure accurate offsets, set out right angles for rectangles and plot boundaries in survey practicals and outdoor maths activities.

  • Setting out right angles on the ground
  • Measuring perpendicular offsets from a chain line
  • Chain surveying practicals
  • Laying out rectangles and field plots
