Air-Spaced Doublet Lens Assemblies

UV-VIS Achromatic

Over the years, We have designed many unique achromatic lens systems and collimators to cover the UV through visible. These designs include monochromator input collimators, imaging systems and other specially designed systems. Please inquire about our library of such designs. It is possible that we have already built a system to meet special application. Utilizing such a design or a modification thereof may likely avoid the expense of a new design. Below are listed some of our standard UV-VIS Achromatic Lenses. These are corrected for the infinite conjugate, that is optimized for focusing an infinitely distant object, or for collimating from a point source at the focal point.
PLEASE NOTE : Because light sources are extended, that is of finite size, it is difficult to describe image quality in terms of theoretical blur-circles. These are air-spaced doublets consisting of one element of calcium fluoride with the other of UV grade fused silica, uncoated, mounted in our standard black anodized cell. Design details available on request.

Visible Achromatic

Our two-element, air-spaced achromats are designed for diffraction-limited focusing in the visible spectrum. The lenses are mounted in a black-anodized cell. All four surfaces are anti-reflection coated for the visible spectrum so that transmittance exceeds 96% These are "fast" lenses, being f/4, and designed for focusing or collimating.

Laser Collimators

Our Laser Collimator Lenses are designed for monochromatic operation at any laser wavelength from 400 nm to 1.5 еьm, and will focus within diffraction - limit theory. These "fast" f/4 air-spaced doublets are mounted in a black anodized cell. All surfaces are antireflection coated so that transmittance will exceed 96% at the specified wavelength of operation. When ordering, specify wavelength for antireflection coatings. Other Laser Collimator Lenses are available. Please inquire.

Notes : specify еы from 400nm to 1.5еьm, for example LLS-25-100-633
