Hardwood Case and Edge Marked Lenses
Each cylindrical lens kit comes with a hardwood storage case. All lenses include easy to identify edge-marked product model numbers.
N-BK7 Master Set
These lens sets provide a comprehensive selection of lens shapes and focal lengths in N-BK7 optical glass. Plano-convex lenses are provided with focal lengths from 25.4 to 300 mm. Plano-concave lenses are provided with focal lengths from -75 to -200 mm.
N-BK7 Introductory Set
These lens sets provide a more economical selection of lenses that can be expanded as required. Like the BK 7 Master Sets, the lenses in these sets are made from quality N-BK7 optical glass. Only plano-convex lenses are included in this streamlined version of the Master Set.
Antireflection coatings can significantly improve the transmission of a multi-element optical system. Any of our broadband AR coatings are available as standard lens kit options. Laser line V-coatings are also available on request.
