Apochromatic lenses for telescopes

Our enterprise manufactures apo-objectives (apochromatic objectives) having enhanced color correction and imagery diffraction quality. These apochromatic lenses are applied in astronomical professional and semi-professional telescopes.

Special glass type OK-4 designed and melted in LZOS allows to achieve perfect color correction within visible range of spectrum. OK-4 glass similar to fluorite has unique optical parameters. Made of OK-4 apo-lenses (apochromatic lenses) ensure image quality characterized by round-mean-square wavefront deviation not exceeding 0.035 wavelength (532nm). In June 2005 LZOS has started production of 12" F/12 Super Apo Astronomical lens ... more detail < detailed about apochromatic lenses >
