BK7 Plano-Convex Lens Ø2.0 mm f = 4 mm AR Coating 350 - 700 nm

Features

• Material: N-BK7
• AR-Coated for the 350 - 700 nm Range
• Focal Lengths Available from 4 to 2500 mm

Plano-convex lenses can focus a collimated beam or collimate light from a point source. To minimize the introduction of spherical aberration, a collimated light source should be incident on the curved surface of the lens when being focused and a point light source should be incident on the planar surface when being collimated.

This BK7 Plano-Convex Lens has a diameter of 2.0 mm and a focal length of 4 mm. It has a multi-layer anti-reflection coating that is optimized for the 350–700 nm range in the visible spectrum, ensuring minimal light loss and maximum performance. Made of BK7 material, this lens is durable and offers optimal optical performance in many applications.
