43-891 15 mm Dia. Borofloat33 Protective Flat Window; t=1.75 mm Uncoated

The 43-891 is a 15 mm diameter, 1.75 mm thick uncoated Borofloat33 protective flat window, available from Edmund Optics. This window is designed for use in optical systems where a flat, transparent barrier is required. The Borofloat33 material offers excellent optical properties, making it suitable for a wide range of applications.

Borofloat33, also known as borosilicate glass 3.3, is a low-expansion glass with high thermal resistance. It is known for its excellent transmittance across a wide spectrum, from the ultraviolet to the infrared regions. This makes it an ideal choice for applications that require high visibility and clarity.

The window features a circular base shape and a thin lens design. The thin lens design helps to minimize optical distortion, ensuring that the image passing through the window remains clear and undistorted. The window is uncoated, meaning it does not have any additional layers applied to enhance its optical properties. However, this also means that it may be more susceptible to environmental factors such as dust, dirt, and moisture.

The 43-891 window is currently in stock and can be purchased directly from the Edmund Optics website. With its robust design and high-quality materials, this window is a reliable choice for a variety of optical applications.
