连续可变中性密度滤光片是精确调节分光光度计、单色仪和激光器的理想之选。这些滤光片的光学密度在其长度方向上呈线性连续变化。通过成对使用，这些滤光片能够有效控制直径达25.4毫米的光束透射。连续可变中性密度滤光片特别适合于400-700nm的波长范围。滤光片尺寸为25.4 x 76.2毫米，提供多种光学密度选项。
Edmund Optics' Continuously Variable Neutral Density Filters are designed for dynamic light management. These filters feature a durable Inconel coating, delivering consistent spectral performance while enabling seamless light intensity control. Ideal for machine vision, optical spectroscopy, and dynamic imaging setups, they allow users to fine-tune transmission levels without the need to swap multiple fixed filters, simplifying complex experimental and production environments.
These filters offer a continuously adjustable optical density from OD 0.04 to OD 4.0. Before making a selection, check each filter's specifications.
They are ideal for optical spectroscopy, machine vision systems, applications requiring dynamic light control, and general visible light experiments.
Each filter is constructed of a float glass substrate and coated with Inconel, offering excellent durability and consistent optical performance across the visible spectrum.
