This product is a 36-579 12.5 mm Dia. AR Coated Sapphire Protective Flat Window, offered by Edmund Optics. It is a circular window with a diameter of 12.5 mm and a thickness of 1 mm, designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically at a wavelength of 587.6 nm.
The window is made of sapphire, also known as aluminum oxide (Al2O3), which is a highly durable and scratch-resistant material. This makes it an ideal choice for protective applications where the window may be exposed to potential damage.
The window features anti-reflective (AR) coatings on both the front and back surfaces. These coatings, identified as 'edm visnir0sp2002000', are specifically designed to reduce reflection in the VIS-NIR spectrum, enhancing transmittance and improving overall optical performance.
The window is shaped as a thin lens, suggesting that it may have some light-bending properties, although this is not explicitly stated in the provided data.
