36-437 25 mm Dia. NIR Metallic Based Neutral Density Filter; OD 5 700-1100nm

The 36-437 is a 25 mm diameter Neutral Density Filter, specifically designed for use in the Near-Infrared (NIR) spectrum with a wavelength of 588 nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase through their website, where it is currently listed as in stock.

This filter is part of the Neutral Density Filter sub-type, which is characterized by its ability to reduce the intensity of all wavelengths of light equally, resulting in a neutral color balance. This makes it an ideal choice for applications where light intensity needs to be controlled without altering the color composition.

The filter is circular in shape, with a diameter of 25 mm and a thickness of 3 mm, making it suitable for use in a variety of optical systems. The material ID for this filter is UVFS MAL-1965, although further details about the material composition are not provided in the item data.

The 36-437 filter features a coating on both the front and back surfaces, identified as EDM 36-436. This coating likely contributes to the filter's performance in the NIR spectrum. The filter's shape is described as a Thin Lens, indicating that it is designed to minimize optical aberrations and distortions.
