FNP0150 50 x 50 mm Gelatine Neutral Density Filter 546nm

The FNP0150 is a 50 x 50 mm Neutral Density Filter, specifically designed with a wavelength of 546nm. This filter is sourced from Knight Optical, a reputable vendor known for its high-quality optical elements.

The filter is made of gelatine, a material identified as UVFS MAL-1965 in the item data. This material is known for its excellent optical properties, making it an ideal choice for various optical applications. The filter's rectangular base shape is designed to fit into most optical systems, providing versatility and convenience.

The FNP0150 has a thickness of 0.1mm, which is considered thin in the context of optical elements. This thinness contributes to its lightweight nature, making it easy to handle and integrate into optical systems. The filter's geometry, including its width and length, is standardized at 50mm each, ensuring compatibility with common optical mounts and holders.

The filter features a coating on both the front and back surfaces, identified as 'kni fnp01'. This coating is likely designed to enhance the filter's performance, such as by reducing reflections or increasing durability. The exact nature of the coating, however, is not specified in the item data.

The filter's shape is described as 'Thin Lens', suggesting that it may have some lens-like properties. However, without additional information, it is difficult to specify what these properties might be.
