⚡ At a Glance
- • Image Quality: High transmission acrylic helps produce brighter, more legible projected images
- • Best for: Teachers, students and hobbyists conducting projector demos and simple optical experiments
- • Not ideal for: Applications that require precision glass optics or permanent, high-end projection systems
A pair of rectangular Fresnel lenses made from optical acrylic, sized 90 x 140 mm. Designed for projection assistance, magnifying tasks and classroom optics demonstrations.
Sharper Projection – With high-transmission acrylic construction
Concentric grooves on a thin acrylic sheet bend and focus light across a large aperture, while the acrylic material maintains strong light transmission. The grooved surface mimics a thicker lens profile without bulk.
Brighter, more readable images when used with small projectors, making slides and diagrams easier to see in demonstration settings.
Clear Optical Demos – Thanks to the 90 x 140 mm viewing area
A sizeable rectangular aperture provides a visible field large enough to observe focal effects and magnification, enabling straightforward alignment with projected beams. The flat format sits easily on screens or samples.
Students can follow beam paths and focal changes without elaborate mounts, so lessons become more hands-on and engaging.
Portable Magnification – With a thin, flexible acrylic sheet
Thin acrylic construction keeps weight low and allows gentle bending for close-contact magnification, while maintaining optical transparency. The flexible format folds or slides into kits for transport.
Quick magnifier for reading or inspecting small details, convenient to carry between lessons or projects.
