Infinity Corrected Objective Lens

Infinity corrected objectives are used in a wide variety of imaging and laser focusing applications. Light rays leaving the objective’s rear aperture are collimated, so that for imaging applications, a secondary lens (usually called a tube lens) is needed in order to focus the collected light from the specimen onto the sensor. The labeled magnification is calculated, assuming the objective is being used with a tube lens of a particular focal length by design. When a tube lens of a different focal length is used, the magnification will need to be adjusted accordingly. As an advantage over finite conjugate objective lenses, a variety of auxiliary optical components, such as optical filters and polarizers can be inserted between the infinity objective lens and the tube lens without altering how the beam propagates and forms the image down the optical path. In laser applications such as optical tweezers and laser cutting, laser beams entering the rear aperture of an infinity objective can be tightly focused to a diffraction-limited spot, providing concentrated optical power and excellent resolution.

聚焦和准直的理想之选

Newpoort 的 LI 系列物镜专为整个可见光谱的衍射极限性能而设计，其可将来自激光器（例如，氦氖、氩或倍频 Nd:YAG）的准直光束聚焦到一个小光斑。我们的显微镜物镜具有宽带 AR 涂层，以便最大限度地传输光线。

空间滤波应用

LI 系列显微镜物镜可用于 900 或 910 空间滤波系统。通过选配物镜和相应的针孔，可以对激光束进行空间滤波，从而改善输出光束质量。
