These are lenses with one flat surface and one convex surface. They have a positive focal length and are used to converge or focus incoming light. They are best for infinite conjugate systems. They can be used in many different optical systems such as magnifiers, telescopes, collimators, condensers and imaging instruments. For best optical performance, the convex side should always face the incident light.
Below are our standard specifications.
