Nkọwa dị mkpirikpi:

Igwe anya silicon monocrystalline mkpuchi bụ ihe na-arụ ọrụ ngwa anya dabere na silicon monocrystalline silicon (Si) dị ọcha site na nhazi ngwa anya na teknụzụ mkpuchi. Silicon Monocrystalline nwere ezigbo nnyefe ọkụ na band infrared (1.2-7μm), yana jikọtara ya na mkpuchi dị ka ihe nkiri mgbochi ntụgharị (AR), ihe nkiri dị elu (HR) ma ọ bụ ihe nzacha, ọ nwere ike imeziwanye nnyefe ma ọ bụ ntụgharị uche nke otu ìgwè. A na-eji ngwaahịa ndị a eme ihe na infrared imaging, laser optics na nchọpụta semiconductor.

Njirimara oghere silicon mkpuchi:

1. Ọrụ anya:
Oke nnyefe: 1.2-7μm (nke dị nso na infrared na etiti infrared), nnyefe> 90% na 3-5μm ikuku windo band (mgbe mkpuchi gasịrị).
N'ihi nnukwu refractive index (n≈ 3.4@4μm), ihe nkiri mgbochi nchegharị (dị ka MgF₂/Y₂O₃) kwesịrị ka a na-edobe iji belata nhụsianya elu.

2. Nkwụsi ike okpomọkụ:
Low thermal mgbasa ọnụọgụ (2.6 × 10⁻⁶ / K), elu okpomọkụ eguzogide (arụ ọrụ okpomọkụ ruo 500 ℃), adabara elu ike laser ngwa.

3. Mechanical Njirimara:
Mohs hardness 7, nkwụsi ike ọkọ, mana nnukwu brittleness, chọrọ nchebe chamfering ihu.

4. Njirimara mkpuchi:
Customized anti-reflection film (AR@3-5μm), high reflection film (HR@10.6μm for CO₂ laser), bandpass filter film, etc.

Ngwa lens silicon mkpuchi mkpuchi:

(1) Infrared thermal imaging usoro
Dị ka akụkụ bụ isi nke anya anya infrared (3-5μm ma ọ bụ 8-12μm band) maka nlekota nchekwa, nyocha ụlọ ọrụ na akụrụngwa ọhụụ abalị.

(2) Laser ngwa anya usoro
CO₂ Laser (10.6μm): oghere reflector dị elu maka resonators laser ma ọ bụ ntugharị ọkụ.

Fiber laser (1.5-2μm): oghere ihe nkiri na-emegide echiche na-eme ka arụmọrụ njikọ dị mma.

(3) Ngwa nyocha nke Semiconductor
Ebumnuche microscopic infrared maka nchọpụta ntụpọ wafer, na-eguzogide corrosion plasma (nchebe mkpuchi pụrụ iche chọrọ).

(4) ngwa nyocha nke spectral
Dị ka akụkụ dị iche iche nke Fourier infrared spectrometer (FTIR), nnyefe dị elu na mgbagha ihu ihu dị ala dị mkpa.
