Variable Metallic Neutral Density Filter Beamsplitters

Variable Metallic Neutral Density filters can be used as beamsplitting optics for many applications where the splitting ratio needs to be varied. For holographic and interferometric applications, a specific splitting ratio is required which makes it difficult to find off the shelf catalog optics. This product is the ideal solution for varying the splitting ratio as needed. There may be situations where the user may need to change lasers to generate a good result, so they end up switching to a stronger laser source and perhaps even to a new wavelength.  This variable beamsplitter is well suited for different laser wavelengths due to the broadband metallic coating.
