Lens caps are important for protecting expensive camera lenses from damage. Dust, grit, and other nasty things will all quickly spoil the quality of a shot, and can even permanently damage a lens if ...

This technique shared by [Andy Kong] is for 3D printed lenses, but would probably be worth a shot for any resin prints that need to be made nice and clear. The link to his post on X is here, but we’ll ...

A new method to make a low-cost, high-quality lens quickly using a 3D printer has promising potential to create optical imaging lenses, customized contact lenses for correcting distorted vision, or to ...

Researchers detail how they used a type of 3D printing known as two-photon lithography to create lenses that combine refractive and diffractive surfaces. In a new study, researchers have shown that 3D ...
