ND2R10B Dia. 50 mm Unmounted Reflective ND Filter; Optical Density 1.0

The ND2R10B is a Neutral Density Filter with a diameter of 50 mm, manufactured by Thorlabs. This unmounted filter is designed with a thin lens shape and a thickness of 2 mm, making it a compact and versatile option for various optical applications.

The filter is made from N-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures high-fidelity light transmission, making it suitable for applications that require precise light control.

The ND2R10B features a front and back coating of THo ND10, a reflective neutral density coating. This coating reduces the intensity of incident light without altering its color composition, providing a consistent and uniform attenuation. The optical density of 1.0 implies that the filter reduces the light intensity by a factor of 10, offering a significant level of light control.

The filter's circular shape and thin lens design allow for easy integration into various optical systems. It is currently in stock and available for purchase through the vendor's website, as indicated in the item data.
