OPB-80C12-20-2 80 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=12 mm Uncoated

The OPB-80C12-20-2 is a high-quality optical window from OptoSigma, designed with precision and durability in mind. This window is a flat, circular shape with a diameter of 80 mm and a thickness of 12 mm, making it suitable for a wide range of optical applications.

The window is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The N-BK7 Schott used in this window ensures high transparency and low auto-fluorescence, making it ideal for applications that require high light transmission and low background noise.

The window is designed to operate at a wavelength of 588 nm, which covers a significant portion of the visible light spectrum. This makes it suitable for use in a wide range of applications, from simple light transmission to more complex optical systems.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in applications where the natural properties of the glass are desired, or where additional coatings could interfere with the system's operation. However, it's important to note that uncoated windows may be more susceptible to environmental factors such as dust, moisture, and scratches.

The window is available from OptoSigma and is currently in stock, according to the vendor's website. This ensures quick and reliable delivery, making it a convenient choice for those needing a high-quality optical window promptly.
