MAN-30-40 30 mm Dia. Optical Glass Mounted Absorptive Neutral Density Filter 400-700nm

OptoSigma's MAN-30-40 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 absorption is uniform across the spectrum, ensuring color neutrality and preventing any shifts in hue. The absorptive nature also makes this filter less susceptible to surface damage, such as scratches or dirt, which can affect the performance of reflective filters.

The MAN-30-40 features a Thin Lens shape, with a diameter of 30mm and a thickness of 2mm. This design ensures minimal interference with the light path, making it suitable for use in compact optical systems. The filter is coated on both the front and back with Opt and-40, a coating that enhances the filter's performance and durability.
