Nā Paʻa Lens

Hoʻohana ʻia ka paʻa lens e hoʻopaʻa a mālama i ke kūlana o nā optics āpau i ka hui lens. ʻO ke kumu nui o ka mea paʻa lens e hāʻawi i ka paʻa a paʻa i nā optics i kahi paʻa. Hiki ke hoʻohana ʻia nā mea paʻa lens me nā kānana, polarizers, pinholes, a me nā mea geometry-adaptive he nui. ʻO ke koho kūpono o ka mauna lens e pili ana i ka noi, optics, ka pololei i makemake ʻia, a me ka helu o nā kuhikuhi hoʻoponopono. He manaʻo hou paha ke kumu kūʻai, ma muli o ka nui o nā ʻāpana optical e pili ana.

Nui nā ʻano lens mounts i loaʻa e paʻa i nā lens o nā ʻano like ʻole a me nā ʻano. Loaʻa i nā papa maʻamau nā papa paʻa, nā papa paʻa me nā apo hoʻopaʻa, nā papa biaxial, nā papa honua, a me nā kiʻi ponoʻī. ʻO ka mauna Lens Paʻa me ka Paʻa Screw Hoʻokahi he mea maʻalahi, haʻahaʻa kumu kūʻai mauna lens mauna. Ke koi ʻia ka pololei waena, e hoʻohana i ka mauna lens paʻa me ke apo paʻa. He mauna mauna ili keia, aka, ua kikoo kela me keia mauna i ke anawaena lens. ʻO ka mauna lens axis ʻelua he mauna lens paʻa me kahi apo paʻa e hiki ai ke hoʻololi i ke kūpaʻa a me ke ākea o nā optics. Hāʻawi nā puʻu lens ʻelua axis i ke kūlana pololei, akā kikoʻī kēlā me kēia mauna i ka nui o ke anawaena lens. Hiki ke hoʻohana ʻia me nā lens lens ākea ākea. ʻAʻole hiki i nā puʻu lens universal ke kumu i nā hewa kikowaena a loaʻa kahi kūlana paʻa e pili ana i ke axis optical. Loaʻa nā puʻu lens hoʻokohukohu ponoʻī me nā anawaena lens like ʻole, a ʻo ke kikowaena o ka lens e hoʻopili mau ʻia me ke axis optical. Ma muli o ko lākou paʻakikī, hiki ke ʻoi aku ke kumukūʻai o kēia mau mauna ma mua o nā puʻu lens maʻalahi.

Hoʻolālā kūikawā ʻia paha kekahi mau mea paʻa lens e paʻa i kahi pahuhopu, kahi ʻano o nā lens ana, a i ʻole kahi collimator. ʻO nā ʻano puʻu lens ʻē aʻe e pili ana i nā puʻu aniani, prism a me cube beamsplitter mounts, kānana mauna, nā puʻu polarizer rotating, pinhole a me nā puʻu slit, mauna fiber, a me nā mauna laser cylindrical.
