Fused Quartz Prism
Daim duab qhia ntxaws
Txheej txheem cej luam ntawm Quartz Prisms
Fused quartz prisms yog qhov tseem ceeb ntawm cov khoom siv kho qhov muag siv los tswj, tswj xyuas, thiab hloov lub teeb nyob rau hauv ntau qhov kev ua haujlwm siab kho qhov muag. Tsim los ntawm ultra-high purity fused silica, cov prisms no muaj tshwj xeeb kis tau tus mob nyob rau hauv lub ultraviolet (UV), pom, thiab ze-infrared (NIR) spectral ranges. Nrog zoo thermal thiab tshuaj tsis kam, zoo heev mechanical zog, thiab tsawg kawg nkaus birefringence, fused quartz prisms yog zoo tagnrho rau cov ntaub ntawv tseem ceeb hauv spectroscopy, laser optics, imaging, thiab scientific instrumentation.
Fused quartz yog non-crystalline, amorphous daim ntawv ntawm silicon dioxide (SiO₂) uas nthuav tawm tsis tshua muaj impurity theem thiab superior kho qhov muag homogeneity. Cov yam ntxwv no tso cai rau fused quartz prisms ua nrog qhov cuam tshuam tsawg, txawm tias nyob rau hauv ib puag ncig huab cua.
