010-0230E 25.4 mm Dia. N-BK7 Plano-Concave Window; t=6mm Uncoated

This 010-0230E optical component is a Plano-Concave Window, sourced from EKSMA Optics, a renowned vendor in the optical industry. 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 -5000 mm, resulting in an effective focal length (EFL) of 9671.47 mm. This specific curvature and thickness combination make it an ideal choice for applications requiring precise optical path control and minimal spherical aberration.

The material of this window is N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including high transparency and low dispersion. This material is often used in high-precision optical systems due to its superior performance.

The window is designed to operate at a wavelength of 588 nm, making it suitable for applications in the yellow-orange part of the visible light spectrum. It is important to note that the window does not come with any coating, which means it is uncoated. This may affect its performance in certain applications, particularly those requiring high reflectivity or specific polarization characteristics.
