Multi-element Lenses
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.
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.
