66-187 20 mm Dia. N-BK7 Ultra-Thin Protective Flat Window; t=0.2 mm Uncoated

The 66-187 is a 20 mm diameter uncoated ultra-thin protective flat window, featuring a thickness of 0.2 mm. This window is made from N-BK7, a popular glass type from Schott, known for its excellent optical properties. The window is designed in a flat configuration, ensuring a uniform optical path and minimal distortion.

The window's geometry is circular, making it suitable for a wide range of applications where a circular aperture is required. The N-BK7 material is renowned for its high refractive index and low dispersion, making it an ideal choice for applications that require high-quality imaging or precise light control.

This window is uncoated, meaning it does not have any anti-reflective or other surface coatings. While coatings can enhance the performance of optical elements in specific applications, an uncoated window can be advantageous in certain scenarios due to its simplicity, cost-effectiveness, and durability.

The window is sourced from Edmund Optics, a leading vendor in the optical industry, ensuring high quality and reliability. According to the vendor, the window is currently in stock, indicating its availability for immediate purchase and delivery.
