Ka Hoʻololi Mea, Ka Hana ʻana i ka Curve, CNC Grinding and Polishing
ʻO ka mea mua, ua hoʻololi ʻia nā mea maka i ke ʻano like o ka lens, e hōʻemi ana kēia i ka manawa i hoʻopau ʻia ma hope o ke kaʻina hana.
ʻO ka mua o kekahi mau ʻanuʻu wili no nā optic curved ʻo ia ka hana curve, kahi kaʻina hana wili e hana i ka curvature spherical maʻamau o ka lens.ʻO kēia kaʻina hana no ka wehe ʻana i nā mea a hana i ka radius spherical maikaʻi loa ma nā ʻaoʻao ʻelua o ka lens, nānā ʻia ka radius o ka curvature me ka spherometer i ka wā o ke kaʻina hana.
No ka hoʻomākaukau ʻana no ka hoʻokele helu kamepiula a i ʻole CNC grinding, pono e hoʻopili ʻia ka ʻāpana spherical i kahi mea paʻa metala ma kahi kaʻina i kapa ʻia ʻo blocking.Hoʻohana ʻia kahi mea hana wili asphere sub-aperture i loaʻa nā ʻāpana liʻiliʻi o ke daimana no ka wehe ʻana i ka mea a hana i ka ʻili aspheric.Hoʻohana kēlā me kēia ʻanuʻu wili i nā ʻāpana daimana ʻoi aku ka maikaʻi.
ʻO ka hana aʻe ma hope o kekahi mau pōʻai o ka wili ʻana ʻo ia ka CNC polishing, hoʻohana ʻia ka cerium oxide polishing compound i kēia kaʻina no ka wehe ʻana i ka pōʻino i lalo o ka ʻili a hoʻololi i ka ʻili o ka honua i kahi mea i poni ʻia e nānā ʻia ma lalo o kahi microscope e hōʻoia i ka lens e hoʻokō i ka maikaʻi o ka ʻili i ʻōlelo ʻia.
Hoʻohana ʻia ka metrology in-process e nānā i ka mānoanoa waena, aspheric surface profile a me nā ʻāpana ʻē aʻe a e hana i ka hoʻoponopono ponoʻī ma waena o nā ʻanuʻu wili a me ka polishing.
ʻO CNC Grinding a Polishing vs Conventional Grinding and Polishing
Hoʻohana ʻo Paralight Optics i kekahi mau hiʻohiʻona o ka computer numerically controlled a CNC grinders a polishers, kēlā me kēia mea i hoʻopaʻa ʻia no kahi ʻano nui o nā lens, hiki iā mākou ke hana i nā anawaena lens mai 2mm a 350mm.
Hāʻawi nā mīkini CNC i kahi hana kūpaʻa a me ke kumu kūʻai, akā hiki ke hoʻohana ʻia nā mea wili maʻamau a me nā polishers e nā mea akamai a me nā ʻenehana loea me ka ʻike waiwai a hana i nā lens pololei loa.
ʻO CNC Grinders a me nā Polishers
ʻO nā mea wili maʻamau a me nā poni
Mīkini kikowaena
Hoʻohana ʻo Paralight Optics i ka Mīkini Centering Manual a me ka Mīkini Centering Auto ma ka wili ʻana i kona anawaena o waho, hiki iā mākou ke hoʻokō i kahi kikowaena a hiki i 30 arcseconds, maʻalahi i ka 3 arcminutes kikoʻī no ka hapa nui o kā mākou optics.Hoʻāʻo ʻia ke kikowaena ma hope o ke kikowaena e hōʻoia i ka hoʻohālikelike ʻana o nā axes optical a me mechanical.
