MAN-30-70 30 mm Dia. Optical Glass Mounted Absorptive Neutral Density Filter 400-700nm
OptoSigma's MAN-30-70 is a high-quality Neutral Density Filter, designed to provide consistent attenuation across the visible spectrum, specifically within the 400-700nm range. This filter is mounted on a 30mm diameter optical glass, making it an ideal choice for various optical applications.
The filter is of the Absorptive type, meaning it reduces light intensity by absorbing it rather than reflecting or scattering. This results in a more precise and uniform attenuation. The front and back of the filter are coated with 'opt and-70', a coating that enhances the filter's performance and durability.
The filter's geometry is defined by a diameter of 30mm and a thickness of 2mm, giving it a Thin Lens shape. This design ensures minimal distortion and maintains the integrity of the optical path. The filter is identified by the Material ID 'uvfs mal- 1965', which can be useful for cataloging and cross-referencing.
The filter's wavelength is centered at 550nm, making it suitable for applications that require a balanced attenuation across the visible spectrum. The catalog number 'MAN-30-70' can be used to easily locate this item on OptoSigma's website, where it is currently in stock.
