215-0122 15 mm x 20 mm; N-BK7 Flat Rectangular Window; t=2 mm Uncoated

The 215-0122 is a Flat Rectangular Window, sourced from EKSMA Optics, designed to meet the demands of various optical applications. This window boasts a base shape of a rectangle, with a width of 15 mm and a length of 20 mm, providing a substantial surface area for light transmission.

The window is fabricated from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, making it an ideal choice for a wide range of applications, particularly in the visible spectrum. The window's thickness is 2 mm, providing sufficient structural integrity while minimizing optical distortion.

This window is uncoated, offering bare optical glass for applications where coating is not required or preferred. The uncoated surface provides a broadband anti-reflection effect, enhancing light transmission. However, for applications requiring specific reflection or transmission characteristics, coatings can be applied.

The window's geometry is that of a thin lens, suggesting its potential use in focusing or collimating light beams. However, its primary function is as a window, providing protection for optical components while allowing light transmission.

Please note that the window's wavelength is 633 nm, indicating its design for use in red light applications. However, due to its high transmittance across the visible spectrum, it can be used in other visible light applications as well.
