This product is a 20 mm diameter Sapphire Flat Window, offered by the renowned optical vendor, Edmund Optics. The window is designed with a thickness of 2 mm, making it a robust and reliable option for various applications.
The window is made from Sapphire, a material with the ID al2o3 mal-1972-n-o. Sapphire is known for its exceptional hardness, second only to diamond, making it highly resistant to scratches and abrasions. It also has excellent thermal shock resistance and is transparent across a wide spectrum, from ultraviolet to infrared wavelengths.
The window features Anti-Reflective (AR) coatings on both the front and back surfaces. These coatings are of the MgF2 type, with a standard curve. The AR coatings are designed to operate within the wavelength range of 400-700 nm, which covers the visible light spectrum. The coatings significantly reduce reflective losses, thereby enhancing the transmittance of light through the window.
The window is shaped as a Thin Lens, which can be beneficial in certain optical systems where minimal optical power is desired. The window is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
