Ideal for laser-focusing applications, 10 to 30-mm Gradium Series lenses use glass with an axial gradient that changes the lens index by as much as 0.15 from front to back to correct aberrations. Two ...

The near-axial aberrations such as spherical aberration, coma aberration, and chromatic aberration are well corrected by computer optimization design. When used to focus the collimation, the surface ...

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 ...

Fast imaging is of great interest in microscopy, computer vision, and laser machining. For example, in neuroscience, high-speed volumetric imaging is essential to monitor dynamic biological processes, ...
