49-070 25 mm Dia. NIR Metallic Based Neutral Density Filter; OD 0.9 700-1100nm

The 49-070 is a 25 mm diameter Neutral Density Filter, specifically designed for use in the Near-Infrared (NIR) spectrum with a wavelength of 588nm. This filter is manufactured by Edmund Optics, a leading provider of optical components. The filter is part of their extensive catalog, which includes a wide variety of optical elements from different vendors worldwide.

The filter is circular in shape and has a base material identified as "uvfs mal- 1965". It features a neutral density of 0.9, which is designed to reduce the intensity of light without altering its color balance. This makes it an ideal choice for applications where light intensity needs to be controlled, such as in photography, laser applications, and scientific research.

The filter has a diameter of 25mm and a thickness of 3mm, making it suitable for use in a variety of optical systems. The coating on both the front and back surfaces of the filter is "edm 49-068", which is likely a proprietary coating developed by Edmund Optics to enhance the performance and durability of their filters.

The filter is designed with a thin lens shape, which helps to minimize optical aberrations and distortions. This is particularly important in applications where high precision and accuracy are required.
