Primary colours filters Manufacturer,Supplier and Exporter in India
Product Code : SCL-OS-12882
The Educational Instrument Primary Colour Filters help students observe how selected colours of light pass through a filter while other parts of visible light are reduced or absorbed. The set supports practical teaching of red, green, and blue primary light colours, which are central to additive colour mixing demonstrations.
These filters are suitable for use with a safe classroom light source, ray box, filter holder, optical bench, or colour demonstration kit. They can be used alone for basic light-transmission observation or combined with secondary filters, colour charts, and vision activities for a wider optics lesson.
Key Features
Set of 3 primary colour filters for red, green, and blue light activities.
Supports additive colour mixing, light transmission, and colour perception lessons.
Useful with ray boxes, light sources, filter holders, optical benches, and screens.
Helps students compare transmitted colour and filtered light intensity.
Simple classroom accessory for repeated supervised optics demonstrations.
Suitable for school physics labs, STEM labs, colleges, and science exhibitions.
Can be paired with secondary colour filters and colour triangle charts.

Applications / Uses
Teaching red, green, and blue primary light colours in physics lessons.
Demonstrating how colour filters transmit selected parts of visible light.
Explaining additive colour mixing and RGB colour formation.
Comparing filter behaviour with Colours and Vision Kit activities.
Using with a Filter Holder to keep filters aligned in the light path.
Supporting optical experiments in Optical Sectional equipment setups.
How to Use the Primary Colour Filters
Place a safe light source, ray box, or classroom lamp on a stable table.
Insert one primary colour filter into a suitable holder or place it in the light path.
Observe the colour of light transmitted through the filter on a white screen.
Repeat the observation with the red, green, and blue filters separately.
Overlap coloured beams where the apparatus permits additive colour mixing.
Ask students to record colour changes and compare results with the RGB model.
Safety note: use filters only under teacher supervision. Do not look directly into bright lamps, laser beams, projector beams, or concentrated optical outputs.
Care & Maintenance
Wipe filters with a soft, dry cloth after use.
Store the filters flat in a clean, dry box to prevent scratches.
Keep filters away from heat, moisture, chemicals, and sharp objects.
Handle filters by the edges to avoid fingerprints on the optical surface.

Frequently Asked Questions
What are Primary Colour Filters used for?
Primary Colour Filters are used to demonstrate red, green, and blue light transmission, colour filtering, additive colour mixing, and basic colour perception in physics and STEM lessons.
Which colours are included in the set?
The set includes three primary colour filters: red, green, and blue. These are used to teach the RGB colour model for light.
Can these filters be used with a ray box?
Yes. Primary colour filters can be used with a ray box, light source, optical bench, screen, and suitable filter holder during supervised experiments.
Are Primary Colour Filters suitable for school laboratories?
Yes. They are suitable for school physics labs, college laboratories, STEM classrooms, teacher demonstrations, and science activity programmes.
What material are the filters made from?
The exact material is not verified for the standalone filter set. Confirm the supplied material before listing plastic, acrylic, glass, or any other specific construction.
Do these filters require electricity?
The filters do not require electricity by themselves. A separate safe light source may be used for transmission and colour mixing demonstrations.
