Home optics accessory for adjustable beam control and DIY projection builds. Makes experimenting and fine-tuning beam width straightforward for hobbyists, stage technicians and educators. Is the JINGERL Fresnel Lens the right fit for your next lighting or optical experiment?

⚡ At a Glance
  • Beam Control: Adjustable focal lengths let users change beam spread, focus and output angle
  • Best for: DIY hobbyists, stage lighting technicians and educators needing flexible optics
  • Not ideal for: Applications demanding finished, housed optics or high-resolution photographic lenses

Eight Fresnel focal lengths are included, ranging from 28 mm to 67 mm. Suited to LED lights, stage lights, flashlights and small DIY projectors for experiments and prototyping.


Tailored Beam Widths – With multiple focal length options

Different focal lengths control where light converges and how wide the output angle becomes; shorter focal lengths tend to produce broader beams while longer ones tighten the focus. Swapping lenses or changing distance between light source and lens directly alters beam spread.

Easily match beam width to the application, whether widening a lantern spill or narrowing a stage spotlight for a sharp hotspot.

Practical DIY Projection – Thanks to compact Fresnel profiles

Thin, stepped Fresnel geometry concentrates light with far less bulk than conventional lenses, making compact projection and VR test rigs simpler to assemble. Pairing a strong LED with an appropriate focal length produces a focused image plane for small-scale projection.

Lens selection and simple mounting lets users build or test small projectors and VR focus setups without large optics.

Magnified Observation for Testing – With magnifying capability

Fresnel lenses can enlarge details when placed at the correct object-to-lens distance and illuminated adequately, enabling close inspection or imaging trials. The sample range supports quick comparisons across focal lengths for experimental setups.

Useful for classroom demonstrations, component inspection and optical product development where quick magnification and comparison are required.
