Achromatic Doublets

Lens ya achromatic, yomwe imadziwikanso kuti achromat, imakhala ndi zigawo ziwiri zowoneka bwino zolumikizidwa palimodzi, nthawi zambiri zimakhala ndi index yotsika (nthawi zambiri imakhala ndi magalasi agalasi a biconvex) ndi chinthu chapamwamba choyipa (monga galasi la mwala). Chifukwa cha kusiyana kwa ma refractive indices, kufalikira kwa zinthu ziwirizi kumalipirana pang'ono, kusintha kwa chromatic ponena za mafunde awiri osankhidwa kwakonzedwa. Amakonzedwa kuti azitha kuwongolera pa-axis spherical and chromatic aberrations. Lens ya Achromatic ipereka kukula kwa malo ang'onoang'ono ndi chithunzi chapamwamba kuposa lens yofananira ndi singlet kutalika komweko. Izi zimawapangitsa kukhala abwino kwa kujambula ndikugwiritsa ntchito ma Broadband. Ma Achromats adapangidwa ndikupangidwa kuti akwaniritse kulolerana kolimba kwambiri komwe kumafunikira pamakina amakono a laser, electro-optical and imaging system.

Paralight Optics imapereka mawonekedwe osiyanasiyana achromatic optics okhala ndi kukula kwamakasitomala, utali wokhazikika, zida zam'munsi, zida za simenti, ndi zokutira zimapangidwira. Ma lens athu achromatic amaphimba 240 - 410 nm, 400 - 700 nm, 650 - 1050 nm, 1050 - 1620 nm, 3 - 5 µm, ndi 8 - 12 µm kutalika kwa mafunde. Amapezeka osakwera, okwera kapena ofananira awiriawiri. Ponena za ma achromatic doublet & triplets line-up, titha kupereka ma double achromatic, ma cylindrical achromatic doublet, awiriawiri achromatic doublet omwe amakongoletsedwa ndi ma conjugates opanda malire komanso abwino pamakina otumizirana zithunzi ndi ma magnification, ma air-spaced achromatic doublet omwe ali abwino kwa mphamvu zambiri. ntchito chifukwa cha kuwonongeka kwakukulu kolowera kuposa ma achromats omangidwa, komanso ma achromatic triplets omwe amalola kuwongolera kopitilira muyeso.

Mapiritsi a Achromatic a Paralight Optics akupezeka ndi zokutira zotchingira kudera lowoneka la 400 - 700 nm, dera lowoneka bwino la 400 - 1100 nm, pafupi ndi dera la IR la 650 - 1050 nm, kapena mtundu wa IR wa 1050 - 1700 nm wavelength. Amakongoletsedwa kuti azitha kuchita bwino kwambiri m'magawo owoneka bwino komanso apafupi ndi infrared (NIR), zokutira za antireflection (AR) zimawapangitsa kukhala oyenera kugwiritsa ntchito ma microscopy a fluorescence. Chonde yang'anani chithunzi chotsatirachi cha zokutira pazolinga zanu. Mapiritsi a Achromatic amagwiritsidwa ntchito ngati zolinga za telescope, zotchingira m'maso, magalasi okulitsa ndi zowonera. Mapiritsi a Achromatic adagwiritsidwanso ntchito kuyang'ana ndikuwongolera matabwa a laser chifukwa mawonekedwe awo azithunzi ndi apamwamba kuposa ma lens amodzi.
