Fresnel Lens Pair for DIY Projectors

Build a compatible DIY projector optical path with a selected Fresnel-lens pair supplied without holders.

✅ Plan the light path as a pair - Front and rear lens selections provide the described optical components for a suitable projector design.

✅ Choose dimensions for the build - Different type selections offer lens configurations for the intended optical layout.

✅ Keep the component format flat - Plastic Fresnel construction provides the described thin, stepped-lens arrangement.

Match the optics before building the housing

A projector build needs lens dimensions and focal lengths that work with the display, light source and imaging optics. Select the actual Fresnel pair around that optical design rather than the screen size alone.

Type A and Type B have different sizes and focal lengths, and other selections need their own matching specification. Holders are not included, so provide suitable mounting and keep the lenses away from concentrated sunlight.
