Key Features
Holder slot takes colour filters, optical filter plates and suitable light filters Keeps the filter aligned so light passes evenly through it Used for transmission, absorption, colour filtering and colour mixing experiments Works with ray boxes, laser ray boxes, lamps, LED light sources and optical benches Filters can be swapped quickly to compare colours Technical Specifications
Specification Value Application Holding optical filters during light, optics, colour and ray experiments Compatible with Colour filters, optical filters, ray boxes, laser ray boxes, light sources, optical benches, optics kits Main concepts Light transmission, absorption, colour filtering, colour mixing, light intensity comparison Operation mode Manual optical experiment accessory
About This Product
Holding a filter by hand in a beam makes results hard to compare, while a holder fixes its position so the only thing that changes is the filter itself. Students can then judge how each colour transmits or absorbs light and compare the intensity before and after the filter.
Frequently Asked Questions
