210-0102M 12.5 mm Dia. N-BK7 Flat Round Window; t=2 mm Uncoated

The 210-0102M is a Flat Round Window, a type of optical component designed for use in various applications. This particular model boasts a diameter of 12.5 mm and a thickness of 2 mm, making it a compact and versatile option.

The window is made from N-BK7, a popular material in the optical industry due to its excellent optical properties. This specific type of glass, often referred to as BK7, is known for its low dispersion and high transmittance across a wide range of wavelengths. In this case, the window is designed for use with a wavelength of 633 nm.

The window's shape is defined as a Thin Lens, which suggests that it has been designed to minimize optical aberrations. This makes it suitable for use in high-precision applications where optical quality is paramount.

Notably, this window is uncoated. While coatings can be applied to optical components to enhance their performance, an uncoated window can be advantageous in certain situations. For instance, it can offer broader wavelength compatibility and reduced cost compared to coated alternatives.

This window is provided by EKSMA Optics, a reputable vendor in the optical industry. The web link provided in the item data indicates that the window is currently in stock, ensuring quick and efficient delivery.
