Acromatic doublets are cemented achromats consisting of two different lenses: Positive low dispersion crown glass and negative high dispersion flint glass.
An economical achromat for general use, suitable for an optical system that does not require high surface quality imaging, such as a microscope or telescope objective.
By combining two lenses with different wavelength dispersion and refractive index, the resulting component provides lower spherical aberration and chromatic aberration than a single spherical lens.
Achromatic lenses that have a negative focal length.
A cylindrical achromat is a single component made by joining two cylindrical surface lenses with different refractive indices.
These lenses, 20 mm in length, are made of a synthetic fused silica material and have a high transmission value in the ultraviolet wavelength range of 180 - 400 nm.
These lenses with a length of 12 mm are made of a synthetic fused silica material and have a high transmission value in the ultraviolet wavelength range of 180 - 400 nm.
These lenses contain elements that have different refractive indices and produce a high degree of correction over a bandwidth of 200 - 400 nm.
Visible spectrum achromats are air-bearing achromatic doublets for visible spectrum lasers or white light applications.
High-performance multi-element focusing lenses. Doublets.
YAG laser focusing lenses are air-bearing doublets for YAG wavelengths.
Visible spectrum achromats are air-bearing achromatic triplets for visible spectrum lasers or white light applications.
