WG70530-G 0.5in Dia. AR Coated; ZnSe Broadband Precision Window; t=3 mm 7-12µm
The WG70530-G is a high-quality, broadband precision window offered by Thorlabs. This window, designed for general-purpose use, boasts a 0.5-inch diameter and a thickness of 3 mm, making it a versatile and robust option for various optical applications.
The window is made from ZnSe (Zinc Selenide), a material known for its excellent optical properties, including high transparency in the infrared region (7-12 µm). This makes it an ideal choice for applications that require efficient transmission of light in this spectral range.
The WG70530-G features anti-reflection (AR) coatings on both the front and back surfaces. These coatings, identified as 'tho gznsearc70001200', are designed to minimize reflection and maximize transmission, further enhancing the window's performance.
The window's geometry is that of a thin lens, which can be beneficial in certain optical configurations. However, it's important to note that this window is not designed to focus light; its primary function is to provide a transparent barrier with minimal optical distortion.
