NE501B Dia. 0.5 in Absorptive ND Filter; Optical Density 0.1
The NE501B is a Neutral Density (ND) Filter, designed and manufactured by Thorlabs. This filter is circular in shape, with a diameter of 12.7 mm and a thickness of 0.6 mm, making it suitable for a wide range of optical applications. The NE501B features a n-bk7 schott material ID, ensuring high-quality performance and durability.
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 tho ne01a coating on both the front and back surfaces. The optical density of this filter is 0.1, which corresponds to a reduction factor of approximately 1.26 in light intensity.
The NE501B filter is designed with a thin lens shape, which can be beneficial in certain optical systems where minimal thickness is required. The catalog number for this item is NE501B, and it is currently in stock on the Thorlabs website. For more information or to make a purchase, please visit the provided weblink.
