Njirimara nke Lens Optic SiC

1. Ịdị Elu Ihe

Ike Mgbanwe Gburugburu Ebe Obibi Dị Oke: Na-eguzogide okpomọkụ karịrị 1500°C, mmebi siri ike nke acid/alkali, na radieshon ike dị elu, nke dị mma maka ụgbọ elu na ebe nuklia.

Ike Mekaniki Pụrụ Iche: Ike siri ike nke dị nso na dayamọnd (Mohs 9.5), ike flexural karịrị 400 MPa, na iguzogide mmetụta nke karịrị iko anya nkịtị.

Nkwụsi Ike nke Okpomọkụ: Ọkwa okpomọkụ dị elu karịa silica a gwakọtara agwakọta 100×, yana CTE naanị 1/10 nke iko nkịtị, na-eme ka ọ kwụsie ike n'okpuru usoro okpomọkụ ngwa ngwa.

2. Uru Arụmọrụ Anya

Mgbasa ozi sara mbara (0.2-6 μm); mkpuchi pụrụ iche nwere ike ime ka nnyefe dịkwuo mma ruo >95% na mpaghara ụfọdụ (dịka ọmụmaatụ, 3-5 μm n'etiti IR).

Mfu dị ala nke mgbasa ozi (<0.5%/cm), njedebe elu ruo ọkọlọtọ 10/5 nke nchịkọta ihe, na ịdị larịị nke elu λ/10@633 nm.

Oke mmebi dị elu nke laser kpatara (LIDT) >15 J/cm² (1064 nm, 10 ns pulses), nke dabara adaba maka sistemụ lesa ike dị elu.

3. Ike Ịrụzi Ihe nke Ọma

Na-akwado elu dị mgbagwoju anya (aspheric, freeform) na izi ezi nke ọdịdị <100 nm PV na centration <1 arcmin.

Nwere ike imepụta anya SiC buru ibu (dayameta karịrị 500 mm) maka telescopes mbara igwe na optics mbara igwe.

Ngwa Ndị Mbụ nke Lens Optical SiC

1. Ihe ngosi mbara igwe na nchekwa

Anya igwe na-ahụ maka ihe ngosi anya satịlaịtị na anya igwe na-ahụ maka oghere, na-eji ihe ndị dị mfe nke SiC (njupụta 3.21 g/cm³) na iguzogide radieshon eme ihe.

Windo anya nke na-achọ ngwa agha, nke na-adịgide ruo okpomọkụ ikuku (>1000°C) n'oge ụgbọelu hypersonic.

2. Sistemụ Laser Ike Dị Elu

Lensị lensị maka ngwa ịkpụ/ịgbado ọkụ laser ụlọ ọrụ mmepụta ihe, na-ejigide oge dị ogologo na lasers na-aga n'ihu na kW-klas.
