LBTEK Air-Spaced Achromatic Doublets deliver a spot size close to the diffraction limit, with optical designs that correct for most aberrations. Compared to cemented doublets, they offer a higher damage threshold. These doublets are designed for broad wavelength ranges. For different coating options, LBTEK uses three typical wavelengths in the lens design: For 350–700 nm AR coating: 486.1 nm, 587.6 nm, and 656.3 nm；For 650–1050 nm AR coating: 706.5 nm, 855 nm, and 1015 nm. All LBTEK lenses are precision-manufactured under strict quality control, ensuring high-quality optical products at competitive prices.
