Yaikulu-kakulidwe Machining Kutha

Magalasi akulu akulu (omwe nthawi zambiri amatengera zinthu zowoneka bwino zoyambira masentimita makumi angapo mpaka ma mita angapo) amagwira ntchito yofunika kwambiri paukadaulo wamakono wamakono, ndikugwiritsa ntchito magawo angapo monga kuyang'ana zakuthambo, laser physics, mafakitale opanga mafakitale, ndi zida zamankhwala. Zotsatirazi zikufotokozera zochitika zogwiritsira ntchito, ntchito, ndi zochitika zenizeni:

1, Kuthekera Kwakusonkhanitsa Kuwala Kwambiri

Mfundo yofunikira: Kukula kwa lens kwakukulu kumafanana ndi kabowo kakang'ono ka kuwala (malo ogwira ntchito), zomwe zimathandiza kusonkhanitsa mphamvu zambiri zowunikira.

Kagwiritsidwe Ntchito:

Kuyang’anira Zakuthambo: Mwachitsanzo, magalasi aakulu 18 a beryllium a James Webb Telescope amajambula kuwala kwa nyenyezi kuchokera pa mtunda wa zaka 13 biliyoni za kuwala kwa zaka 13 biliyoni pokulitsa malo ounikira.

2, Kusintha kwa Optical Resolution ndi Kujambula Kwambiri

Mfundo: Malinga ndi muyezo wa Rayleigh, kukula kwa kabowo ka mandala, kumapangitsa kuti diffraction-limited resolution (njira: θ≈1.22λ/D, pomwe D ndi mainchesi a lens).

Kagwiritsidwe Ntchito:

Masetilaiti Owona Kutali: Magalasi a zolinga zazikulu (monga ma lens a 2.4-mita a satellite ya US Keyhole) amatha kuthetsa zolinga zapansi pa sikelo ya mita 0.1.

3, Kusinthasintha kwa Gawo Lowala, Makulitsidwe, ndi Polarization

Kuzindikira mwaukadaulo: Mawonekedwe a mafunde a kuwala amasinthidwa kudzera mu mawonekedwe a pamwamba (mwachitsanzo, parabolic, aspheric surfaces) kapena njira zokutira pa mandala.

Mapulogalamu Odziwika:

Ma Gravitational Wave Detectors (LIGO): Magalasi akulu akulu osakanikirana a silica amasunga kukhazikika kwa gawo la kusokoneza kwa laser kudzera mu mawonekedwe apamwamba kwambiri (zolakwika <1 nanometer).

Polarization Optical Systems: Ma polarizer akulu akulu kapena ma wave plate amagwiritsidwa ntchito mu zida za laser kuti athe kuwongolera polarization ya ma lasers ndikukhathamiritsa zotsatira za kukonza zinthu.
