Ƙarfin Mashina Mai Girma

Manya-manyan ruwan tabarau na gani (yawanci ana nufin abubuwan da suka shafi gani tare da diamita daga dubun santimita zuwa mita da yawa) suna taka muhimmiyar rawa a cikin fasahar gani na zamani, tare da aikace-aikacen da suka mamaye fagage da yawa kamar kallon sararin samaniya, kimiyyar lissafi laser, masana'antar masana'antu, da kayan aikin likita. Mai zuwa yana yin ƙarin bayani kan yanayin aikace-aikacen, aiki, da kuma lokuta na yau da kullun:

1, Ingantaccen Ƙarfin Tarin Haske

Ƙa'ida: Girman ruwan tabarau mai girma yayi daidai da mafi girma-bude haske (yanki mai tasiri), yana ba da damar tarin ƙarin makamashin haske.

Yanayin aikace-aikacen:

Duban Astronomical: Misali, manyan lensin beryllium 18 na na'urar hangen nesa ta James Webb ta kama hasken tauraro daga shekaru biliyan 13 mai nisa ta hanyar fadada wurin tattara haske.

2, Ingantattun Ƙwararrun Ƙwararru da Ƙirar Hoto

Ƙa'ida: Dangane da ma'auni na Rayleigh, mafi girman buɗewar ruwan tabarau, mafi girman ƙuduri mai iyakancewa (formula: θ≈1.22λ/D, inda D shine diamita na ruwan tabarau).

Yanayin aikace-aikacen:

Tauraron Dan Adam na Nesa: Manyan ruwan tabarau na haƙiƙa (misali, ruwan tabarau na mita 2.4 na tauraron dan adam na Maɓalli na Amurka) na iya warware maƙasudin ƙasa a sikelin mita 0.1.

Ganewar Fasaha: Halayen Wavefront na haske ana canza su ta hanyar ƙirar siffa (misali, parabolic, filaye mai aspheric) ko matakan shafi akan ruwan tabarau.

Aikace-aikace na yau da kullun:

Masu Gano Wave na Gravitational (LIGO): Manyan ruwan tabarau na silica fused mai girma suna kula da kwanciyar hankali na lokaci na tsangwama ta hanyar sifofin saman madaidaici (kurakurai <1 nanometer).

Polarization Optical Systems: Ana amfani da manyan polarizers masu girma ko faranti a cikin kayan sarrafa Laser don sarrafa yanayin polarization na lasers da haɓaka tasirin sarrafa kayan.
