Lense e koahetsoeng ka silicon e monocrystalline silicon e tloaelehileng e koahetsoeng ka filimi ea AR e khahlanong le reflection
Litšobotsi tsa lense tsa silicon tse koahetsoeng:
1. Ts'ebetso ea Optical:
Lekhalo la phetiso: 1.2-7μm (haufi le infrared ho ea bohareng ba infrared), transmittance >90% in the 3-5μm atmospheric window bend (kamora ho roala).
Ka lebaka la index e phahameng ea refractive (n≈ 3.4@4μm), filimi e khahlanong le ho bonahatsa (e kang MgF₂ / Y₂O₃) e lokela ho kenngoa ho fokotsa tahlehelo ea ho bonahatsa bokaholimo.
2. Thermal botsitso:
Coefficient e tlase ea ho atolosa mocheso (2.6 × 10⁻⁶/K), ho hanyetsa mocheso o phahameng (mocheso o sebetsang ho fihlela ho 500 ℃), o loketseng lisebelisoa tse phahameng tsa laser.
3. Thepa ea mochini:
Mohs hardness 7, khanyetso ea scratch, empa brittleness e phahameng, e hloka tšireletso e matla.
4. Litšobotsi tsa ho roala:
Customized anti-reflection film (AR@3-5μm), high reflection film (HR@10.6μm for CO₂ laser), bandpass filter film, etc.
Lisebelisoa tsa lense tse koahetsoeng ka silicon:
(1) Sistimi ea ho nahana ka mocheso oa infrared
E le karolo ea mantlha ea lilense tsa infrared (3-5μm kapa 8-12μm band) bakeng sa tlhahlobo ea ts'ireletso, tlhahlobo ea indasteri le lisebelisoa tsa pono tsa bosiu tsa sesole.
(2) Laser optical system
CO₂ Laser (10.6μm) : Lense e phahameng ea ho bonahatsa bakeng sa li-resonator tsa laser kapa ho tsamaisa marako.
Fiber laser (1.5-2μm) : Lense ea filimi ea anti-reflection e ntlafatsa katleho ea ho kopanya.
(3) Lisebelisoa tsa ho hlahloba semiconductor
Sepheo sa microscopic sa infrared sa ho lemoha sekoli, se hananang le kutu ea plasma (ts'ireletso e khethehileng ea ho roala e hlokahalang).
(4) lisebelisoa tsa tlhahlobo ea spectral
E le karolo ea spectral ea Fourier infrared spectrometer (FTIR), phetiso e phahameng le ho khopama ha maqhubu a tlase hoa hlokahala.
Litekanyetso tsa tekheniki:
Lense ea silicon e entsoeng ka monocrystalline e fetohile karolo ea bohlokoa e ke keng ea nkeloa sebaka tsamaisong ea infrared optical ka lebaka la phetisetso ea eona e ntle ea khanya ea infrared, botsitso bo phahameng ba mocheso le litšoaneleho tse ka khonehang tsa ho roala. Litšebeletso tsa rona tse ikhethileng tsa moetlo li netefatsa ts'ebetso e ntle ka ho fetisisa ea lilense ho lisebelisoa tsa laser, tlhahlobo le litšoantšo.

XKH Ts'ebeletso e ikhethileng
XKH e fana ka ts'ebetso e felletseng ea lilense tsa silicon tse koahetsoeng: Ho tloha ho khetho ea silicon ea monocrystalline (resistivity> 1000Ω·cm), ts'ebetso e nepahetseng ea optical (spherical/aspherical, surface accuracy λ/4@633nm), ho roala ka tloaelo (anti-reflection/high reflection/filters) ho ts'ehetsa, ho ts'ehetsa meralo e mengata ea laser tlhahlobo ea ho tšepahala), tšehetsa batch e nyenyane (likotoana tse 10) ho hlahisa lihlahisoa tse kholo. E boetse e fana ka litokomane tsa tekheniki (coating curves, optical parameters) le ts'ehetso ea ka mor'a thekiso ho fihlela litlhoko tse batloang ke lisebelisoa tsa infrared optical system.
