Features

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). The collimated beam should enter or depart from the surface (R₁ in drawing) with higher curvature (smaller radius) for optimized performance.

AR.15 Broadband UV-Visible Antireflection Coating

Our AR.15 broadband multilayer antireflection coating markedly improves the transmission efficiency of these lenses by reducing surface reflections over a 225-700 nm wavelength range. This coating enables use with any or all of the 2nd, 3rd, and 4th harmonic Nd:YAG wavelengths, or for use in UV fluorescence imaging applications.
