Optical Alignment Pin

Quick answer: The LabEquip Optical Alignment Pin is a physics laboratory accessory used to check and set the common axis of components on an optical bench. It gives students and instructors a visible reference point for aligning lenses, mirrors, apertures, screens and light sources before running quantitative optics experiments in school, college and university labs.

Product Description

The alignment pin provides a visible reference point along an optical bench. When one or more pins are positioned along the bench, their tips can be viewed along the bench axis to identify differences in height or lateral position between components, so they can be adjusted into a common line before an experiment begins.

Correct preliminary alignment helps reduce tilted images, off-centre beams and inconsistent measurements in later experiments. The pin material, shaft dimensions, tip design, base configuration and optical-bench compatibility are not confirmed in this listing, so we have not invented these details. Please verify these parameters with our sales team before combining the pin with your existing apparatus.

Specifications

Suggested Procedure

• Mount alignment pins at the positions of the optical components you plan to use.
• Sight along the bench axis and compare the height and lateral position of each pin tip.
• Adjust the bench components until all pin tips line up along a common axis.
• Remove the alignment pins and replace them with the actual optical components at the confirmed positions.
• Proceed with your experiment, re-checking alignment if components are moved.

Safety Note

Handle the pin carefully as its tip may be sharp. Keep pins secured on the bench so they do not roll or fall during use.

Care & Maintenance

• Wipe the pin clean after use and check the tip for bending or damage.
• Store pins in a dedicated tray or case to prevent loss or damage.
• Check that the pin still seats firmly in its bench mount before each use.

Frequently Asked Questions

What is the Optical Alignment Pin used for?

It is used to check and set a common optical axis on a bench, giving a visible reference point to align lenses, mirrors, apertures, screens and light sources before an experiment.

Is the alignment pin compatible with any optical bench?

Bench compatibility is not confirmed in this listing. Please confirm with our sales team which bench types this pin fits before ordering.

Do I need more than one alignment pin?

Typically two or more pins are used together so their tips can be sighted along the bench axis to compare height and lateral position, though the exact quantity supplied is not confirmed in this listing.

How should I store and maintain the alignment pin?

Wipe the pin clean after use, check the tip for bending or damage, and store it in a dedicated tray or case to prevent loss or damage.
