Knight Optical光学材料，氟化镁光学窗口，偏振器

氟化镁（MgF2）是一种无色、坚硬耐用的双折射材料。该材料的耐久性以及对机械和热的抵抗力震动使其能够在恶劣的条件下以窗户的形式使用，而双折射使其对UV波段中的偏振器有用。它在之间传输0.1µm和7µm之间，在0.4-5.0µm之间超过90%。氟化镁具有硬度约为HK576，使其成为光学氟化物中最硬的。 Material: Germanium Diameter: +0.0/-0.2mm Thickness: ±0.2 Surface Flatness @ 633nm: <2λ over 90% CA Surface Quality (S/D): <60/40 Parallelism: <5’ Diameter: 2mm to 300mm+ Thickness: 0.1mm to 50.0mm+ Surface Flatness @ 633nm: <1 fringe Surface Quality (S/D): <20/10 Parallelism: <1’ Part No. D (mm) T (mm) Coating Sides WGE1000 10 2 Uncoated None WGE2500 25 1 Uncoated None WGE2501 25 2 Uncoated None WGE2502 25.4 1 Uncoated None WGE3200 32 3 Uncoated None WGE1212 12.5 1 AR/AR 3-12um Both WGE2542 25 1 AR/AR 3-12um Both WGE2544 25 3 AR/AR 3-12um Both WGE5012 50 1 AR/AR 3-12um Both WGE5014 50 3 AR/AR 3-12um Both WGE1211 12.5 1 AR/DLC 7-14um Both WGE2533 25 3 AR/DLC 7-14um Both WGE3033 30 3 AR/DLC 7-14um Both WGE5033 50 3 AR/DLC 7-14um Both WGE5011 50 10 AR/DLC 7-14um Both WGE7533 75 3 AR/DLC 7-14um Both WGE10011 100 10 AR/DLC 7-14um Both
