Product Code : SCL-LAO-11290
The Optics Alignment Needle is an optical bench accessory used for establishing a visible reference point during alignment, parallax and image-position experiments. It helps students, teachers and laboratory technicians position optical components along a common axis and compare the location of an image with a physical reference point.
Product Description
The Optics Alignment Needle provides a narrow, clearly defined point that can be viewed through or beside lenses, mirrors and other optical components. When mounted vertically on a compatible carrier or base, the needle can help users check component height, optical-axis alignment and the apparent position of an image.
The accessory is suitable for educational optical benches and supervised geometrical-optics experiments. Its needle material, overall height, tip profile, support construction, height-adjustment method and bench-carrier compatibility must be confirmed from the current manufacturing specification.
Key Features
- Defined reference point: Provides a narrow tip for comparing physical and optical image positions.
- Optical-axis alignment: Helps users position experimental components at a consistent working height.
- Parallax observation: Supports image-location activities in which apparent movement is compared with a reference needle.
- Bench-based operation: Can be used with a compatible optical carrier, base or holder.
- Simple visual setup: Requires no electrical power or complex preparation.
- Reusable laboratory accessory: Suitable for repeated school and college physics practicals.
- Compact construction: Occupies limited space within an optical experiment arrangement.

How to Use the Optics Alignment Needle
- Fit the needle into its compatible holder, carrier or support base.
- Place it securely on the optical bench or experiment surface.
- Adjust the needle so its tip is level with the optical centre of the lens or mirror.
- Position the other optical components along the same axis.
- View the needle and the optical image from the specified observation position.
- Move the needle or observation point until relative motion is minimised during a parallax experiment.
- Lock the carrier and record the required position measurement.
Safety note: The needle may have a sharp point. Handle it by the support, fit a protective cap during storage and keep it away from the face and eyes.
Care & Maintenance
- Keep the needle straight and do not use it as a lever or marking tool.
- Wipe the needle and support with a clean, dry cloth after use.
- Do not overtighten the height-adjustment or carrier-locking screw.
- Store the accessory upright or in protective packaging with the tip covered.

Frequently Asked Questions
What is an Optics Alignment Needle used for?
It is used as a visible reference point for optical-axis alignment, image-position comparison and parallax experiments.
Can the needle be used as an object in lens experiments?
Yes, when its size, support and position suit the experimental arrangement. Confirm whether the supplied model is intended as an object needle, image needle or both.
What is the no-parallax method?
The observer compares an optical image with the reference needle while changing viewing position. When no relative movement is visible, the image and needle are approximately in the same plane.
Is the needle height adjustable?
Height adjustment has not been verified for this exact product. Confirm the available range and locking method before ordering.
Will it fit any optical bench?
Compatibility depends on the supplied base, stem and carrier dimensions. These should be matched to the intended optical bench.
Is the alignment needle safe for students?
It is suitable for supervised laboratory use. The pointed end should remain capped during transport and storage.
Request the confirmed needle height, material and carrier compatibility, or explore the Light and Optics laboratory equipment category for related optical-bench accessories.
