120 cm wave and geometrical optics bench

Product Code : SCL-OS-12857

The 120 cm Optical Bench by Educational Instrument provides a long, straight optical path for studying geometrical optics and wave optics. Its 120 cm working length gives students enough space to adjust object distance, image distance, lens position, screen position, and optical accessories during practical experiments.

This bench is suitable for focal length measurement, image formation, refraction, diffraction, spectrum observation, and basic interference demonstrations when used with compatible accessories. It fits naturally into the Optical Sectional equipment category and can be paired with holders, glass lenses, light sources, and gratings according to the required experiment.

Key Features

120 cm optical bench for extended ray optics and wave optics experiments.

Supports alignment of lenses, screens, objects, mirrors, light sources, and gratings.

Useful for focal length, image formation, refraction, diffraction, and spectrum demonstrations.

Suitable for senior school, college, university, TVET, and STEM physics laboratories.

Longer working path allows more flexible positioning than compact optical benches.

Compatible with standard optics accessories where holder sizes and mounts match.

Designed for teacher demonstrations and supervised student practical work.

How to Use the 120 cm Wave and Geometrical Optics Bench

Place the 120 cm optical bench on a clean, stable laboratory table.

Mount the light source, object, lens, screen, grating, or mirror using suitable riders and holders.

Align all components so their centres lie on the same optical axis.

Move the lens, screen, or optical element until the required image, focus point, or diffraction pattern is clear.

Record object distance, image distance, screen position, or pattern spacing as required by the experiment.

Repeat the experiment with different lenses, distances, or optical accessories.

Use the readings to calculate focal length, magnification, lens formula values, or wave optics observations.

Safety note: Handle glass lenses, mirrors, and gratings carefully. Do not look directly into intense light sources, laser beams, or concentrated reflected light.

Care & Maintenance

Keep the bench rail clean so sliding riders move smoothly and align correctly.

Store lenses, gratings, mirrors, screens, and holders separately after use.

Do not force riders if they are misaligned, loose, or obstructed.

Clean optical surfaces only with a soft lens cloth and store the apparatus in a dry cabinet.
