WBMA-20C03-10-550 20 mm Dia. N-BK7 Round AR coated Flat Window; t=3 mm 400-700nm

The WBMA-20C03-10-550 is a high-quality optical window offered by OptoSigma. This window, designed for use in optical systems, features a flat design with a circular shape and a diameter of 20 mm. The window has a thickness of 3 mm, providing a robust and stable platform for optical components.

The window is made from N-BK7, a popular glass type in the optical industry known for its excellent optical properties. This material, also known as BK7, is a borosilicate crown glass with a low coefficient of thermal expansion, making it suitable for various applications.

The WBMA-20C03-10-550 is coated with an anti-reflection (AR) coating on both the front and back surfaces. This coating, denoted as "opt m," is designed to reduce reflection across the visible spectrum, specifically between 400 and 700 nm. The AR coating ensures high transmission and minimal loss of light, enhancing the performance of the optical system.

This window is suitable for use in a wide range of applications, including but not limited to, imaging systems, beam delivery systems, and laser applications. With its robust design, high-quality materials, and advanced coatings, the WBMA-20C03-10-550 is an excellent choice for those seeking a reliable and high-performing optical window.
