Precision Aplanatic
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 double achromatic doublet & triplets line-up, titha kupereka ma achromatic doublet (onse okhazikika komanso olondola aplanatic), ma cylindrical achromatic doublet, awiriawiri achromatic doublet omwe amapangidwira ma conjugates opanda malire komanso abwino kwa makina otumizirana zithunzi ndi makulitsidwe, ma achromatic awiri okhala ndi mpweya. omwe ali abwino kwa mapulogalamu amphamvu kwambiri chifukwa cha kuwonongeka kwakukulu kuposa ma achromats opangidwa ndi simenti, komanso ma achromatic triplets omwe amalola kuti pakhale kuwongolera kwakukulu.

Paralight Optics' Precision Aplanats (Aplanatic Achromatic Doublets) sikuti amangowongoleredwa chifukwa chozungulira komanso mtundu wa axial ngati Standard Cemented Achromatic Doublets komanso amawongoleredwa chifukwa cha chikomokere. Kuphatikiza uku kumawapangitsa kukhala aplanatic m'chilengedwe komanso kumapereka mawonekedwe abwinoko. Amagwiritsidwa ntchito ngati zolinga zoyang'ana za laser komanso mu electro-optical & imaging system.
