What it does · where it’s used

  1. Focus, collimate or expand a beam
  2. Form images in cameras, projectors, microscopes and telescopes
  3. Shape a laser beam in one axis with cylindrical lenses
  4. Cut colour fringing with achromatic doublets

01TypesLenses

Eleven types.

Open a type for how it works and where it is used. Each can be made in the material and coating you need.

FIG. 01.01
Three plano-convex lenses on a green background

Plano-Convex Lenses

One flat face, one convex face: the everyday lens for focusing and collimating.

FIG. 01.02
Two double-convex lenses on a dark background with coloured reflections

Double-Convex Lenses

Two convex faces: a positive lens for imaging at near-equal distances.

FIG. 01.03
Two plano-concave lenses on black, one standing on its edge

Plano-Concave Lenses

One flat face, one concave face: a negative lens that spreads light out.

FIG. 01.04
Three double-concave lenses on a dark background

Double-Concave Lenses

Two concave faces: a negative lens for diverging light and expanding beams.

FIG. 01.05
Two positive meniscus lenses on a grey textured surface

Positive Meniscus Lenses

Convex-concave and thicker at the centre: adds focusing power with little aberration.

FIG. 01.06
Two negative meniscus lenses on black

Negative Meniscus Lenses

Convex-concave and thicker at the edge: a diverging lens that helps correct aberrations.

02Also madeLenses

Beyond the standard forms.

  1. 01.A

    Aspheric lenses

    A non-spherical surface cancels spherical aberration, so one element can focus tighter than a spherical lens.

  2. 01.B

    Custom lenses

    Other forms, sizes, materials and coatings, made to your drawing.
