Achromatic Triplets

Nzvimbo yepakati apo maranzi emwenje anopfuura nepakati pelenzi anosanganidzana anosiyana zvishoma kubva panzvimbo panosangana maranzi echiedza anopfuura nemumicheto yelenzi, uku kunonzi spherical aberration; kana mwaranzi yechiedza ichipfuura nepalenzi yakakomberedzwa, nzvimbo yakatarisana nemwenje dzvuku ine kureba kwemasaisai iri kure kupfuura nzvimbo yechiedza cheblue ine hurefu hupfupi, somugumisiro mavara anoita seari kubuda ropa, uku kunonzi chromatic aberration. Sezvo gwara rinoitwa spherical aberration mu convex lens rakapesana ne concave lenzi, kuburikidza ne musanganiswa wemalenzi maviri kana anopfuura mararanzi emwenje anogona kuitwa kuti aenderane kunzvimbo imwe chete, uku kunonzi aberration correction. Achromatic lenzi akakodzera kune ese ari maviri chromatic uye spherical aberrations. Yedu yakajairwa uye tsika achromats akagadzirwa uye akagadzirwa kuti agutse zvakanyanya kuomesesa kushivirira kunodiwa mune yanhasi yepamusoro-inoshanda laser, electro-optical uye imaging masisitimu.

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. The Steinheil triplets yakanyatsogadzirirwa 1: 1 conjugation, vanoita zvakanaka kune conjugate ratios kusvika ku 5. Aya ma lenzi anoita zvakanaka relay optics kune zvose-uye-off-axis application uye anowanzoshandiswa sezviyero zvemaziso.

Paralight Optics inopa Steinheil achromatic triplets ine MgF2 single layer anti-reflective coatings ye400-700 nm wavelength renji pane ese ari kunze, ndapota tarisa inotevera girafu kune ako mareferensi. Dhizaini yedu yelens ndeyekombuta yakagadziridzwa kuve nechokwadi chekuti chromatic uye spherical aberrations zvinoderedzwa panguva imwe chete. Malenzi akakodzera kushandiswa mune akawanda epamusoro resolution ekufungidzira masisitimu uye chero application uko spherical uye chromatic aberrations inofanirwa kudzikiswa.
