Precision Right Angle Alignment with the Double Prism Optical Square

The Double Prism Optical Square is an essential surveying instrument designed for fast and accurate right angle alignment in field applications. Featuring two high-quality pentaprisms mounted in a durable aluminum casing, this tool enables surveyors and engineers to quickly establish perfect 90-degree angles without complex calculations or electronic equipment.

Key Features & Applications:

• Dual Prism Precision: Two premium optical glass pentaprisms ensure accurate right angle reflection

• Versatile Operation Modes:

  • Hand-Held without Plumb: Ideal for quick alignment checks where exact positioning isn’t critical

  • Hand-Held with Plumb: Use with plumb bob for precise vertical alignment from specific points

  • Pole-Mounted: Mount on ranging pole with leveling for consistent height and true vertical alignment

• Robust Construction: Heavy-duty aluminum housing withstands field conditions and minor impacts

• Maintenance-Free Design: Prisms are permanently aligned and cannot go out of calibration

• Field-Proven Accuracy: Achieves ±1cm precision at 30 meters for most surveying applications

Technical Specifications:

• Accuracy: ±1cm at approximately 30 meters

• Construction: Aluminum housing with optical glass pentaprisms

• Applications: Right angle alignment, offset measurements, perpendicular setting

• Maintenance: Clean with alcohol and cotton buds or lens tissue

How It Works: Simply look through the viewing window while positioning the instrument to establish perfect perpendicular lines. The pentaprism technology automatically reflects light at exactly 90 degrees, eliminating calculation errors and ensuring reliable results every time.

Ideal For:

• Land surveying and boundary marking

• Construction layout and building alignment

• Road and pipeline construction

• Agricultural land planning

• Archaeological site mapping

• Any application requiring quick right angle establishment

Complete Package: Ready for immediate use with clear operating instructions.

Why Choose Our Optical Square? This maintenance-free instrument provides reliable right angle alignment in any field conditions.
