The 49-637 is a 5 mm diameter, UVFS round protective flat window with a thickness of 1 mm. This window is designed for use in the visible to near-infrared spectrum, covering wavelengths from 400 to 1000 nm.
The window is made from UVFS material, specifically UVFS Mal- 1965, which is known for its excellent optical properties. This material is often used in applications where high transmission and low absorption are critical.
The window features a VIS-NIR coating on both the front and back surfaces. This coating, identified as edm visnir0sp2002000, is designed to enhance the window's performance in the visible to near-infrared spectrum. It provides superior protection against environmental factors, such as dust, moisture, and other contaminants, while also minimizing reflection and maximizing transmission.
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 shape is often used in applications where a wide field of view is required, such as in cameras and other optical instruments.
The window is available from Edmund Optics, a leading vendor of optical components. According to the vendor's website, the window is currently in stock, making it readily available for immediate use.
