350330-A In Stock

The 350330-A by ThorLabs is an unmounted geltech aspheric lens that offers outstanding performance when collimating light or focusing light without letting the transmitted wavefront gaining spherical aberration. Spherical aberration can limit the diffraction-limited performance of a single spherical lens when working with monochromatic sources, but the 350330-A has been specifically designed to mitigate this issue. This feature makes it an ideal single-element solution for a wide range of applications, including light imaging onto a detector, fiber light coupling, spatial filtering, and output collimation of a laser diode or fiber.

One of the key features of the 350330-A is its antireflection (AR) coating that has been deposited on both sides of the lens. This coating provides excellent performance in the 400 nm - 600 nm range, which makes it an excellent choice for a wide range of applications. With its exceptional optical properties, this aspheric lens can deliver high-quality performance in diverse applications and has become a popular choice for many professionals. For optimal results, it is recommended that the side of the 350330-A with the greater radius of curvature (the flatter surface) should face the point source or laser diode when being used to collimate the light from a point source or laser diode. When using this aspheric lenses to collimate light, it is important to orient the housing so that the externally threaded end of the mount faces the source.
