WQK4040-AV2 40 x 40 mm N-BK7 Precision Rectangular Window; t=6mm AR 450-900nm
The WQK4040-AV2 is a precision rectangular window, measuring 40 x 40 mm, with a thickness of 6mm. This window is made from N-BK7, a high-quality borosilicate glass, which is known for its excellent optical properties and durability. The window is sourced from Knight Optical, a reputable vendor in the optical industry.
This window is designed for use in the visible spectrum, specifically between 450-900nm, making it suitable for a wide range of applications. The window features an anti-reflective (AR) coating on both the front and back surfaces, which enhances its transmission capabilities and reduces unwanted reflections. The coating is of the KNI AV2 type, which is known for its high performance and reliability.
The window is shaped as a thin lens, which is a common design for optical components. This shape allows for efficient light transmission while minimizing optical aberrations. The window's rectangular base shape is also a common design, offering a balance between compactness and ease of alignment.
