010-0205E 25.4 mm Dia. N-BK7 Plano-Concave Window; t=6mm Uncoated

This 010-0205E optical component is a Plano-Concave Window, sourced from EKSMA Optics, a renowned vendor in the field of optical elements. The window boasts a base shape of a circle with a diameter of 25.4 mm, making it suitable for a wide range of applications.

The window's geometry is defined by a thickness of 6 mm at the edge and a radius of curvature (r1) of -250 mm. This specific curvature results in an effective focal length (EFL) of 483.57 mm, which is a crucial factor in determining the window's performance in various optical systems.

The material used in the construction of this window is N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. Specifically, it is a Schott N-BK7, ensuring high-quality performance and reliability.

The window is designed to operate at a wavelength of 588 nm. It features a spherical shape, which is a common choice for optical components due to its ease of manufacturing and excellent optical properties.

Notably, this window is uncoated. Coatings are often applied to optical components to enhance their performance, such as increasing transmission, reducing reflection, or providing environmental protection. However, this window has been left uncoated, which may be suitable for certain applications where specific coating properties are not required.
