34-427 50 mm Dia. N-BK7 Precision Protective Flat Window; t=1 mm Uncoated
The 34-427 is a 50 mm diameter, 1 mm thick uncoated flat window, precision-engineered from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This window is sourced from Edmund Optics, a trusted vendor known for high-quality optical components.
The window's primary function is to protect optical surfaces from environmental hazards such as dust, dirt, and moisture, while minimally affecting the light path. Its 50 mm diameter and 1 mm thickness make it suitable for various applications, including beam manipulation and optical system protection.
The window is made from N-BK7 Schott glass, a borosilicate crown glass known for its low dispersion and high homogeneity. This material is an excellent choice for applications where high optical quality is required, such as imaging systems, interferometers, and spectrometers.
Notably, this window is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance performance in specific applications, an uncoated window offers simplicity, cost-effectiveness, and versatility, making it a suitable choice for many users.
