Hastings Cemented
Achromatic Triplets

Achromatic lenses isarudzo yakanaka yekuda yakanyanya aberration control, sezvo ichipa kuita kurinani kurinani pane spherical singlets.Cemented achromatic doublets inokwana kune akawanda maapplication pane asingaperi conjugates, uye akaiswa simende mapeya maviri akanakira anogumira conjugates.Nekudaro, Achromatic triplets inopa kunyangwe kuita kurinani pane achromatic doublets, senyaya yekuti achromatic triplet ndiyo yakapusa lenzi inogadzirisa ese ekutanga chromatic aberrations uye inopa yakanaka pa-axis uye off-axis kuita.

Achromatic triplets ine yakaderera-indekisi korona yepakati chinhu chakaiswa pakati pezvinhu zviviri zvakafanana zvakakwirira-indekisi yekunze.Aya matatu matatu anokwanisa kugadzirisa zvese axial uye laterial chromatic aberration, uye symmetric dhizaini yavo inopa yakakwidziridzwa mashandiro ane simende maviri.

Hastings achromatic triplets yakagadzirirwa kupa isingaperi conjugate ratio uye inobatsira pakutarisa matanda akasanganiswa uye nekukudza.Mukusiyana, Steinheil achromatic triplets yakagadzirirwa kupa inogumira conjugate reshiyo uye 1: 1 imaging.Paralight Optics inopa zvese Steinheil uye Hastings achromatic triplets ine antireflection coating ye400-700 nm wavelength renji, ndapota tarisa inotevera girafu kune ako mareferensi.
