I-High Purity SiC Optical Lens Cubic 4H-semi 6SP Usayizi Owenziwe Ngokwezifiso

Incazelo emfushane:

Amalensi e-SiC (amalensi e-silicon carbide optical) ayizingxenye zokukhanya ezinembile ezenziwe nge-high-purity silicon carbide (SiC), enikeza izici ze-physicochemical ezihlukile nokusebenza kokubona. Iphawuleka ngokuqhutshwa kwe-ultrahigh thermal conductivity (490 W/m·K), i-coefficient ephansi yokunwetshwa kwe-thermal (4.0×10⁻⁶/K), kanye nokuzinza okuvelele kwemvelo, amalensi e-SiC asephenduke inketho efanele kumasistimu okubona asebenza ezimeni ezimbi kakhulu. Lawa ma-lens abonisa ukusebenza okuhle kakhulu kokudlulisela (ukudlulisela okunganancoated>70%) kuwo wonke ama-ultraviolet kuya kumaza amaza e-infrared akude (0.2-6 μm), okuwenza afanelekele ngokukhethekile amasistimu e-laser enamandla amakhulu, okokusebenza komkhathi, kanye ne-optical imaging ezindaweni ezibucayi zezimboni.

Inqubo yokukhiqiza yamalensi e-SiC ihilela ukugaywa okunembayo, ukupholishwa okunembe kakhulu, nokwelashwa okunamathelayo okukhethekile ukuze kuzuzwe izindawo ezikhanyayo ngokunemba kwe-nanoscale (ukuhwaqeka kobuso <1 nm). Amajiyometri angokwezifiso okuhlanganisa izindawo ezingathi sína ne-aspheric kanye ne-freeform zingakhiwa ukuze zihlangabezane nezidingo zedizayini zesistimu yokubona enembayo ephezulu.

Ukuzinza Kwe-Thermal: I-Thermal conductivity engu-100× ephakeme kune-silica ehlanganisiwe, ene-CTE nje engu-1/10 yengilazi evamile, eqinisekisa ukuzinza ngaphansi kokuhamba ngebhayisikili okushisayo okusheshayo.

2. Optical Performance Izinzuzo

Ukudluliswa okubanzi kwe-spectral (0.2-6 μm); okunamathelayo okuyisipesheli kungakhulisa ukuthunyelwa ku>95% kumabhendi athile (isb, 3-5 μm maphakathi ne-IR).

Ukulahleka kokuhlakazeka okuphansi (<0.5%/cm), ukuqeda phezulu kufika ku-10/5 okujwayelekile kokumba, kanye nokucaba kwendawo λ/10@633 nm.

I-high laser-induced damage threshold (LIDT) >15 J/cm² (1064 nm, 10 ns pulses), ilungele amasistimu okugxilisa amandla amakhulu e-laser.

3. Precision Machining Amakhono

Isekela izindawo eziyinkimbinkimbi (i-aspheric, i-freeform) ngokunemba kwefomu <100 nm PV kanye ne-centration <1 arcmin.

Iyakwazi ukwenza amalensi e-SiC amakhulu kakhulu (ububanzi>500 mm) wezibonakude zezinkanyezi kanye ne-space Optics.

Izicelo Eziyinhloko ze-SiC Optical Lens

1. I-Space Optics & Defense
