Name: 61-6949-66 φ25.4 (BK7) Lens Kit SLB-25.4-SET
Price: 622.26 USD

Features

This lens kit is ideal for everything from teaching materials to research and development.
27 single lenses of 4 types, 9 types of plano-convex and 6 types of biconvex, plano-concave and biconcave, are combined in a special case.
The outside diameter of the lens is φ25.4 mm.
The focal length is finely divided over a wide range of −200~1,000 mm.
The special case is made of a wooden box with a handle for convenient storage.
