About The 31mm Double Convex Lens
Material: PMMA (Acrylic ); Shape: Double Convex,biconvex lens; Lens; Color: Transparent;

Size:
Outer Diameter: approx. 31mm/1.22inch; Lens Height: 12.5mm/0.49inch; Focal Length:27mm; Epitaxial thickness: 3mm/0.12inch

Advantage:
Made of PMMA (Acrylic) material,High-transparency, low-dispersion for sharp image projection.not easy to age,The beam spots irradiated through the optical lens are uniform,scratch-resistant edges for safe handling., without black holes, shadows, or dark areas.Resistant to wear and suitable for repeated use in classrooms or workshops.Smooth.

Instruction:
The installation is simple. Remove the old optical lens of the flashlight lamp holder and replace it with a flat convex lens. It is also very suitable for performing optics and light refraction in physics class.

Application
Optical Double convex lenses are widely used in LED lighting products, such as car lights, bike headlights, focusing flashlights, spotlights, downlights, condensers, optics, floodlights, and other lighting accessories, etc. At the same time, it is also very suitable for performing optics and light refraction in physics class. Ideal for science labs, education, magnifying, photography, and light experiments.Useful for hobbyists, jewelers, and engineers for detailed viewing.

Packing Included:
