The 36-989 is a 5 mm diameter, 1 mm thick Flat Window made from UVFS material, specifically UVFS Mal-1965. This window is designed for use in the Near-Infrared (NIR) region of the spectrum, with a wavelength of 587.6 nm.
The window features a coating on both the front and back surfaces, specifically the EDM NIR-I STD curve. This coating is designed to optimize performance in the NIR region, providing superior protection and durability.
The window is shaped as a Thin Lens, which is a type of lens with a very small focal length compared to its diameter. This makes it ideal for use in applications where space is limited, or where a wide field of view is required.
The window is sourced from Edmund Optics, a leading vendor in the field of optical components. According to the vendor's website, the window is currently in stock, ensuring quick and reliable delivery.
