I-Hastings Ihlanganisiwe
I-Achromatic Triplets

Amalensi e-Achromatic ayinketho enhle yokufuna ukulawulwa kokuhlehla okukhulu, njengoba enikeza ukusebenza okungcono kakhulu kunama-singlets ayindilinga. Okuphindwe kabili okufakwe usimende kwe-achromatic anele izinhlelo zokusebenza eziningi kuma-conjugates angapheli, futhi amapheya kasimende ayi-doublet alungele ama-conjugates anomkhawulo. Kodwa-ke, ama-triplets e-Achromatic anikeza ukusebenza okungcono kakhulu kunokuphinda kabili kwe-achromatic, empeleni i-achromatic triplet iyilensi elula elungisa konke ukuphambuka okuyinhloko kwe-chromatic futhi ilethe ukusebenza okuhle ku-eksisi kanye nokusebenza ngaphandle kwe-axis.

Ama-triplets e-achromatic ahlanganisa ingxenye yesikhungo somqhele enenkomba ephansi efakwe phakathi kwama-elementi amabili afanayo angaphandle anenkomba ephezulu. Lawa ma-triplets ayakwazi ukulungisa kokubili i-axial ne-lateral chromatic aberration, futhi idizayini yawo ye-symmetric inikeza ukusebenza okuthuthukisiwe okuhlobene nokuphindwe kabili kukasimende.

Ama-triplets e-Hastings achromatic adizayinelwe ukuhlinzeka ngesilinganiso esingenamkhawulo we-conjugate futhi awusizo ekugxiliseni imishayo egqunyiwe kanye nokukhulisa. Ngokuphambene, ama-triplets e-Steinheil achromatic adizayinelwe ukunikeza isilinganiso esilinganiselwe se-conjugate kanye nesithombe esingu-1:1. I-Paralight Optics inikeza kokubili i-Steinheil ne-Hastings achromatic triplets nge-antireflection coating yobubanzi be-wavelength engu-400-700 nm, sicela uhlole igrafu elandelayo ukuze uthole izithenjwa zakho.
