A triplet lens is made up of one piece of crown glass with low refractive index and two pieces of flint glass with high refractive index, which can eliminate spherical chromatic aberration of axial direction.

The diameter range of triplet lenses is 1.5-300mm with a diameter tolerance of +/-0.02mm.

The surface quality of triplet lenses ranges from 20-10 with a surface figure of λ/10@633nm and a clear aperture of 90%.

The commonly used materials in triplet lenses include crown glass and flint glass.
