Convex Lenses are widely used in a variety of optical devices. In optical instruments, they used to make magnifying glasses, telescopes, etc. to focus light and magnify the image, and in photography to help focus and improve the image quality, in addition, they are widely used in laser technology to focus the laser beam to improve the efficiency. In the field of lighting, they can be used in flashlights or stage lighting to focus light to achieve the desired lighting effect. They are also ideally for showing optics and the refraction of light in the physics classroom, helping to better understand how optics work.SpecificationMaterial: GlassFocal Length: 50 -75 mmSize: 30x2mm/1.18x0.
