Silicon (Si)
Plano-Convex Lenses

Malenzi ePlano-convex (PCX) ane hurefu hwefocal kureba uye anogona kushandiswa kunangisa danda rakatenderedzwa kuseri kwenzvimbo, kutenderedza chiedza kubva panzvimbo, kana kuderedza kona yakatsaukana yenzvimbo inotsauka. Kuti kuderedze kuiswa kwe spherical aberration, chiedza che collimated chinofanirwa kuitika panzvimbo yakakombama ye lens kana uchishandisa PCX kutarisa chiedza che collimated; Saizvozvo, mwenje wemwenje unotsauka unofanirwa kunge uchiitika pane yakarongwa pamusoro pePCX lens kana ichibatanidza nzvimbo yechiedza. Aya ma lens anoshandiswa mune zvisingaperi uye zvisingaperi conjugate application.

Pakusarudza pakati pe plano-convex lens uye bi-convex lens, izvo zvese zvinokonzeresa kuti collimated chiitiko chiedza chisanganise, zvinowanzova zvakakodzera kusarudza plano-convex lenzi kana kukwidziridzwa kwaunoda kuri pasi pe0.2 kana kupfuura 5. Pakati pezvinhu zviviri izvi, ma-bi-convex lenzi anowanzodiwa.

Silicon inopa yakakwira yekupisa conductivity uye yakaderera density. Zvisinei ine bhendi rakasimba rekunyura pa9 microns, haina kukodzera kushandiswa neCO2 laser transmission applications. Paralight Optics inopa Silicon (Si) Plano-Convex Lenses inowanika nebroadband AR coating yakagadziridzwa ye3 µm kusvika 5 μm spectral renji yakaiswa pane ese ari maviri. Uku kupfekedza kunoderedza zvakanyanya kutaridzika kwepasi peiyo substrate, ichipa yakakwira kutapurirana uye kushoma kunyura pamusoro peiyo AR coating renji. Tarisa maGrafu kune mareferensi ako.
