NE30B-A Dia. 25 mm AR-Coated Neutral Density Filter; 350-700nm; OD 3.0 AR 350-700nm

The NE30B-A is a Neutral Density Filter with a diameter of 25 mm, manufactured by Thorlabs. This filter is designed for use within the wavelength range of 350-700nm, making it suitable for a wide range of optical applications. The filter has a thickness of 2.1mm, which is relatively thin, reducing the risk of vignetting and ensuring ease of integration into optical systems.

The NE30B-A filter is made from UVFS material, identified by the Mal-1965 material ID. This material is known for its excellent optical properties, ensuring high-quality performance. The filter features AR coatings on both the front and back surfaces, specifically designed for the 350-700nm range. This coating helps to minimize reflections and increase transmission, enhancing the overall efficiency of the optical system.

The filter's shape is described as a Thin Lens, which is a type of optical element that focuses light. This shape further expands the potential applications of the NE30B-A filter, making it a versatile choice for many optical systems.

The NE30B-A filter is currently in stock and available for purchase through the Thorlabs website. The catalog number for this item is NE30B-A.
