Zinc Selenide (ZnSe)
Positive Meniscus Lenses
ZnSe lenzi dzakanyanya kukodzera kushandiswa nepamusoro-simba CO2 lasers.Nekuda kweiyo yakakwira refractive index yeZnSe, tinogona kupa spherical yakanakisa fomu dhizaini yeZnSe, inova yakanaka meniscus dhizaini.Aya malenzi anokonzeresa kukanganiswa kudiki, saizi yemavara, uye zvikanganiso zvewavefront zvinofananidzwa neakanakisa fomu lenzi akagadzirwa nezvimwe zvinhu.
Paralight Optics inopa Zinc Selenide (ZnSe) Positive Meniscus Lenses inowanikwa nebroadband AR coating yakagadziridzwa ye8 µm kusvika 12 μm spectral renji yakaiswa panzvimbo dzese dziri mbiri.Uku kupfekedza kunoderedza zvakanyanya kutaridzika kwepamusoro kweiyo substrate, ichipa avhareji yekutapurirana inodarika 97% pamusoro peiyo AR coating renji.
