ʻO ka lens Cylindrical kahi ʻano kūikawā o ka lens cylinder, a hoʻomaʻamaʻa nui ʻia ma ka ʻāpana a me ka lepo ma nā kihi ʻelua.Hana nā lens cylindrical ma ke ʻano e like me ka lens cylinder maʻamau, a hiki ke hoʻohana ʻia i ka hana ʻana i ke kukui a hoʻohuli i ka kukui collimated i kahi laina.ʻO nā lens cylindrical he mau lens optical i hoʻohuli wale ʻia i ka ʻaoʻao hoʻokahi.No laila, hoʻokuʻu a hoʻokaʻawale paha lākou i ke kukui ma ka ʻaoʻao hoʻokahi wale nō, no ka laʻana ma ka ʻaoʻao ākea akā ʻaʻole ma ka ʻaoʻao kū.No nā lens maʻamau, hiki ke ʻike ʻia ko lākou ʻano nānā ʻana a i ʻole defocusing me ka lōʻihi o ke kiko a i ʻole kona inverse, ka mana dioptric.Hiki ke hoʻohana ʻia nā lens cylindrical no ka loaʻa ʻana o ka pahu kukui o ke ʻano elliptical.Hiki ke koi ʻia kēlā, no ka laʻana, no ka hānai ʻana i ka mālamalama ma ka puka komo o kahi monochromator a i ʻole i loko o kahi deflector acousto-optic, a i ʻole no ka hoʻomaʻamaʻa ʻana i ke kukui pahū no ka laser slab.Aia nā collimators axis wikiwiki no nā pahu diode, he mau lens cylindrical - pinepine me ke ʻano aspheric.Hoʻokumu nā lens cylindrical i ka astigmatism o kahi kukuna laser: kahi kūpono ʻole o ke kūlana kikoʻī no nā ʻaoʻao ʻelua.ʻO ka mea like ʻole, hiki iā lākou ke hoʻohana no ka uku ʻana i ka astigmatism o kahi lāʻau a i ʻole kahi ʻōnaehana optical.No ka laʻana, koi ʻia paha lākou no ka hoʻohui ʻana i ka puka o kahi diode laser i loaʻa i kekahi ke kukui non-astigmatic pōʻai.ʻO ke koʻikoʻi nui o ka lens cylindrical, ʻo ia ka hiki ke kuhikuhi i ka mālamalama i kahi laina mau ma mua o kahi kiko paʻa.Hāʻawi kēia ʻano maikaʻi i ka lens cylindrical i nā mana kūikawā like ʻole, e like me ka hanauna laina laser.ʻAʻole hiki ke loaʻa kekahi o kēia mau noi me kahi lens spherical.Hiki i nā lens cylindrical.
