ND2R30B Dia. 50 mm Unmounted Reflective ND Filter; Optical Density 3.0

The ND2R30B is a circular Neutral Density Filter with a 50 mm diameter and a thickness of 2 mm, sourced from the renowned optical component manufacturer, Thorlabs. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an essential tool for various optical applications.

The filter features a front and back coating of tho nd30, a specialized coating developed by Thorlabs. This coating provides an Optical Density of 3.0, which translates to a reduction of 1000x in light intensity. This high level of attenuation makes the ND2R30B ideal for use in high-intensity lighting environments or for extending exposure times in photography and videography.

The ND2R30B is crafted from N-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures the filter maintains high optical quality, reducing the risk of image degradation due to internal scattering or absorption.

The filter's thin lens shape allows for easy integration into various optical systems. It is unmounted, providing users with the flexibility to pair it with their preferred mounting solution. The filter's geometry and material specifications, along with its specialized coating, make it a versatile and reliable choice for a wide range of optical applications.
