355151-A In Stock

The 355151-A by ThorLabs is an exceptional unmounted aspheric lens that is designed to offer superior light collimation and focus while minimizing the impact of spherical aberration in the transmitted wavefront. Featuring a broadband AR coating for the 350 nm - 700 nm range, the 355151-A is an ideal solution for a wide range of applications.

The 355151-A is specifically designed to avoid letting spherical aberration enter the transmitted wavefront and is ideal for applications such as spatial filtering, collimating the output of a laser diode or fiber, imaging light onto a detector, or coupling light into a fiber. Spherical aberration can often prevent diffraction-limited performance from a single spherical lens when collimating or focusing light, particularly for monochromatic sources. When using the 355151-A to collimate the light from a point source or laser diode, it is essential to note that the side with the flatter side that has a greater radius of curvature should face the point source or laser diode.
