我们展示了一种简单易行的方法来生产低反射率表面，该表面兼容超高真空，可以高温烘烤，甚至可以轻松应用于复杂的表面几何形状。黑色氧化铜 (CuO) 表面可在几分钟内在任何铜表面上化学生长，从而实现低成本、快速原型设计和生产。经测量，其反射性能与用于创建光学黑色表面的市售产品相当。我们描述了一种真空装置，该装置使用多个黑铜表面，利用激光诱导荧光对分子进行灵敏、低背景的检测。
We demonstrate a simple and easy method for producing low-reflectivity surfaces that are ultra-high vacuum compatible, may be baked to high temperatures, and are easily applied even on complex surface geometries. Black cupric oxide (CuO) surfaces are chemically grown in minutes on any copper surface, allowing for low-cost, rapid prototyping, and production. The reflective properties are measured to be comparable to commercially available products for creating optically black surfaces. We describe a vacuum apparatus which uses multiple blackened copper surfaces for sensitive, low-background detection of molecules using laser-induced fluorescence.
