Paralight Optics e fana ka mefuta e fapaneng ea li-achromatic optics tse tloaelehileng tse nang le boholo bo hlalosoang ke bareki, bolelele bo tsepamisitsoeng, lisebelisoa tsa substrate, lisebelisoa tsa samente le likoahelo li entsoe ka tloaelo. Lilense tsa rona tsa achromatic li koahela 240 - 410 nm, 400 - 700 nm, 650 - 1050 nm, 1050 - 1620 nm, 3 - 5 µm, le 8 - 12 µm maqhubu a maqhubu. Li fumaneha li sa hloekisoe, li kentsoe kapa li le lipara tse tšoanang. Mabapi le li-doublets tse sa tsitsang tsa achromatic le li-triplets line-up, re ka fana ka li-doublets tsa achromatic (ka bobeli tse tloaelehileng le tse nepahetseng tsa aplanatic), li-cylindrical achromatic doublets, li-achromatic doublet pairs tse ntlafalitsoeng bakeng sa li-conjugate tse fokolang le tse loketseng bakeng sa tsamaiso ea litšoantšo le mekhoa ea ho hōlisa, li-achromatic tse peli tse nang le moea. tse loketseng lits'ebetso tsa matla a holimo ka lebaka la tšenyo e kholo ho feta li-achromats tse samente, hammoho le li-triplets tsa achromatic tse lumellang hore ho be le taolo e phahameng ea ho kheloha.
Paralight Optics' Precision Aplanats (Aplanatic Achromatic Doublets) ha e lokisoe feela bakeng sa ho kheloha ha spherical le axial color joalo ka Standard Cemented Achromatic Doublets empa hape e lokiselitsoe ho koma. Motsoako ona o etsa hore e be aplanatic ka tlhaho mme o fana ka ts'ebetso e ntle ea optical. Li sebelisoa e le sepheo sa ho shebana le laser le lits'ebetsong tsa electro-optical & imaging.
