ND01A Dia. 25 mm ND Reflective Filter; SM1-Threaded Mount; Optical Density 0.1
The ND01A is a Neutral Density Filter with a diameter of 25 mm, manufactured by Thorlabs. This filter is designed with a thin lens shape and an SM1-threaded mount, providing versatility and ease of integration into various optical systems.
The filter's primary function is to reduce the intensity of incident light without altering its color composition. This is achieved through the application of a front and back coating of tho nd01, which provides an optical density of 0.1. This level of optical density corresponds to a reduction of approximately 10% in light intensity.
The filter is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. The filter's geometry, including its 1 mm thickness, is designed to minimize optical aberrations and ensure high-fidelity light transmission.
The ND01A is currently in stock and available for purchase through the Thorlabs website. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
