For applications where multiple focal length doublet lenses may be needed, achromatic lens kits provide a convenient selection of equivalent diameter lenses from which to choose. Our achromatic lens kits are offered in one and two inch diameters. The focal length of the lenses vary from 40-300mm in the one inch and 100 to 1000mm in the two inch lens kit. Each lens comes with an edged marked to help identify its focal length. Achromatic lens kits are offered with broadband visible Anti-Reflection coatings to minimize ghost reflections and losses. All lenses are elegantly arranged in a foam inlaid hardwood box that may be used for permanent storage.
