NE2R50A Dia. 2 in Absorptive ND Filter; SM2-Threaded Mount; Optical Density 5.0
The NE2R50A is a Neutral Density Filter, specifically designed for applications requiring high-quality light absorption. Manufactured by Thorlabs, this filter boasts a catalog number of NE2R50A and is available for purchase directly from their website, which currently indicates that it is in stock.
This circular filter has a diameter of 50.8 millimeters and a thickness of 3.6 millimeters, making it a substantial yet manageable component. It features an SM2-threaded mount, providing a secure and reliable means of attachment to other optical elements.
The NE2R50A filter is coated with a specialized material, identified as "uvfs mal- 1965" in the item data. This coating is applied to both the front and back surfaces of the filter, ensuring consistent light absorption across the entire component.
The filter is designed to operate at a wavelength of 633 nanometers, making it suitable for a wide range of applications. Its shape is described as "Thin Lens", suggesting that it may have some light-focusing properties, although this is not explicitly stated in the item data.
