Images of the smallest cone photoreceptors in the retina, with colour added to represent the different wavelengths of light used to capture the images after compensating chromatic aberration.

Researchers report a new imaging system that cancels the chromatic optical aberrations present in a specific person's eye, allowing for a more accurate assessment of vision and eye health. By taking ...

Designed with new manufacturing technology that creates lenses with shapes that are difficult to fabricate using other methods, Olympus’ new X Line™ series objectives and the UPLAPO-HR objectives for ...

WASHINGTON -- In a new study, researchers have shown that 3D printing can be used to make highly precise and complex miniature lenses with sizes of just a few microns. The microlenses can be used to ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...
