Spherical Lenses
Doublets
Doublet is a cemented lens comprising a positive lens and a negative lens with two different glasses. It provides a doublet with reduced spherical aberrations, reduced color aberrations and sharpened images. We produce cemented and air-spaced achromatic lenses (doublets / triplets). UV grade cement is our standard, other high-temp cements are available upon request. Metal housing, standard and broadband antireflection coatings are available upon request, see our standard optics components below.
