Achromatic Lenses

An Achromat, or Achromatic lens, is usually made up of multiple optical elements, which can be air-spaced or cemented together. These typically alternate a positive lens of low index material, such as crown glass, and a negative lens of high index material, such as flint glass. The elements are selected and optimized so that dispersion in the positive element is corrected by the negative element, resulting in minimized chromatic aberration at two well-separated wavelengths. Achromats offer a nearly constant focal length across the visible spectrum, providing superior off-axis performance. Doublet lenses offer users many more design options than singlet lenses, which allows for superior performance in visual imaging and laser beam manipulation applications. Our lenses are computer designed, minimizing aberrations and providing a smaller focused spot size. They are offered with multi-layer or single-layer AR coatings. Standard diameters and focal lengths may be interchanged with our singlet lenses. Further, achromats are available in a wide variety of configurations, including positive, negative, triplet, and aspherized. These lenses are produced as doublets or triplets (three elements).


MgF2 Visible Antireflection Coating

Our single layer Magnesium Fluoride visible AR coating is the most common choice that offers extremely broad wavelength range at a reasonable price. It is standard on achromats and optional on our N-BK7 plano-convex spherical lenses and cylindrical lenses. Comparing to the uncoated surface, the MgF2 provides a significant improvement by reducing the reflectance to less than 1.5%. It works extremely well over a wide range of wavelengths (400 nm to 700 nm) at angles of incidence less than 15 degrees.

在单色应用中性能卓越

对于在任何可见波长的单色应用,消色差透镜都优于单透镜。负消色差透镜主要用于延长焦距,通常与正消色差镜系统和成像透镜相结合使用。通常,当使用激光器等单色光源时,可以形成衍射极限光斑。


红外性能

虽然可见的消色差透镜未经优化,但是仍可用于红外光中。消色差透镜不会在 1064 nm 处受到衍射限制,但性能仍优于单透镜。在 1064 nm处,典型消色差透镜的焦距增加约 0.75%。与单片型透镜相比,选择这些光学器件将更能满足图像中继或光学处理应用要求。


设计波长

Newport 的可见消色差双合透镜针对可见波长 486.1、546.1 和 656.3 nm 而设计。
