Zinc Selenide (ZnSe)
Positive Meniscus Lenses
ZnSe lo ntsiab muag yog qhov tshwj xeeb zoo rau kev siv nrog lub zog siab CO2 lasers.Vim lub siab refractive Performance index ntawm ZnSe, peb muaj peev xwm muab lub spherical zoo tshaj plaws daim ntawv tsim rau ZnSe, uas yog lub zoo meniscus tsim.Cov lo ntsiab muag no ua rau me me aberrations, qhov ntau thiab tsawg, thiab wavefront yuam kev piv rau cov ntaub ntawv zoo tshaj plaws uas tsim los ntawm lwm cov ntaub ntawv.
Paralight Optics muaj Zinc Selenide (ZnSe) Zoo Meniscus Lenses muaj nrog broadband AR txheej optimized rau 8 µm txog 12 μm spectral ntau yam tso rau ntawm ob qhov chaw.Cov txheej no zoo heev txo qhov siab ntawm qhov pom ntawm lub substrate, ua rau qhov nruab nrab kis tau tus mob ntau dua 97% dhau ntawm tag nrho AR txheej.
