The 36-581 is a high-quality protective flat window offered by Edmund Optics, designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to the wavelength of 587.6 nm. This window is a circular-shaped, thin lens type optical element, boasting a diameter of 20 mm and a thickness of 2 mm.

The window is constructed from sapphire, a highly durable and scratch-resistant material, identified in the item data as al2o3 mal-1972-n-o. This makes it an ideal choice for applications requiring a robust and reliable optical window.
