1.49 CR39 Nā Paʻa Makani Nānā Semi-hoʻopau
He aha nā mea hiki ke hana i nā ʻāpana Lens Semi Finished?
Nā ʻāpana hana lens spectacle e hoʻololi i nā lens semi-hoʻopau i nā lens i hoʻopau ʻia e like me nā ʻano kikoʻī o kahi ʻōlelo kuhikuhi.
ʻO ka hana maʻamau o nā laboratories hiki iā mākou ke hāʻawi i kahi ʻano like ʻole o nā hui optical no nā pono o ka mea hoʻohana, ʻoi aku hoʻi e pili ana i ka hoʻoponopono ʻana i ka presbyopia. Na nā Laboratories ke kuleana no ka hoʻoheheʻe ʻana (wili a me ka polishing) a me ka uhi ʻana (ka waihoʻoluʻu, anti-scratch, anti-reflective, anti-smudge etc.) i nā lens.
No ke aha e koho ai i nā Lenses Optical CR-39?
ʻO Crystal Vision (CR) nā lens maikaʻi loa i hana ʻia e kekahi o nā hui lens nui loa o ka honua.
ʻO CR-39, a i ʻole allyl diglycol carbonate (ADC), he polimer plastik i hoʻohana mau ʻia i ka hana ʻana i nā aniani aniani.
ʻO ka pōkole no "Columbia Resin #39", ʻo ia ka 39th formula o kahi plastic thermosetting i hoʻomohala ʻia e ka Columbia Resins project ma 1940.
Loaʻa iā PPG, ke hoʻololi nei kēia mea i ka hana lens.
ʻO ka hapalua ke kaumaha e like me ke aniani, ʻaʻole hiki ke haki, a ʻoi aku ka maikaʻi o ke aniani.
Hoʻomaʻamaʻa ʻia ʻo CR-39 a ninini ʻia i loko o nā pahu aniani ʻano maikaʻi - hoʻololi pono i nā ʻano o ke aniani.

He aha ke ano lens?
ʻO ka lens freeform maʻamau, he ʻili mua pōpō a me ka ʻili hope ʻekolu-dimensional i hoʻokomo ʻia i ka ʻōlelo kuhikuhi a ka mea maʻi. I ka hihia o kahi lens holomua holomua, ʻo ka geometry ʻili o hope me ka hoʻolālā holomua.
Hoʻohana ke kaʻina hana manuahi i nā lens spherical semi-finished i hiki ke loaʻa ma kahi ākea o nā pihi kumu a me nā kuhikuhi. Hoʻohana pololei ʻia kēia mau lens ma ka ʻaoʻao hope me ka hoʻohana ʻana i nā mea hana hou a me ka polishing e hana i ka papa kuhikuhi pololei.
• ka ili mua he ili poepoe maalahi
• ʻo ka ʻili hope he ʻili paʻakikī ʻekolu
ʻenehana no nā lens manuahi
• Hāʻawi i ka maʻalahi no ka hāʻawi ʻana i kahi ākea ākea o nā huahana kiʻekiʻe, ʻoiai no ke keʻena ʻoihana optical liʻiliʻi
• Pono wale ka waihona o nā pōʻai semi-hoʻopau i kēlā me kēia mea mai kekahi kumu maikaʻi
• Ua maʻalahi ka hoʻokele Lab me ka liʻiliʻi loa o nā SKU
• ʻOi aku ka pili o ka ʻili holomua i ka maka - hāʻawi i nā ʻike ākea ākea ma ke alahele a me ka wahi heluhelu
• Hoʻopuka pololei i ka hoʻolālā holomua i manaʻo ʻia
• 'A'ole i kaupalena 'ia ka pololei o ka palapala kauoha e na mea paahana i loa'a ma ke keena hana
• Hoʻopaʻa ʻia ka hoʻonohonoho pololei ʻana o ka palapala kauoha
