BI-PCV-18-20-N2: 18mm Plano Convex lens, N2 Coated, FL=20mm.
Plano-convex lenses have one flat and one curved surface and a positive focal length. They focus a collimated beam to a point and collimate light from a point source. For the least spherical aberration, face the curved side towards the collimated beam.
