WSI2504 25.4 mm Dia. Silicon Round Window; t=4mm Uncoated

The WSI2504 is a 25.4 mm diameter silicon round window with a thickness of 4mm, sourced from Knight Optical. This uncoated window is a flat, circular optical component designed for use in various applications.

The window is made of silicon, specifically silicon sal vil 1957, which is known for its excellent optical properties. The 25.4 mm diameter provides a substantial aperture, allowing for efficient light transmission. The 4mm thickness offers a good balance between mechanical strength and optical performance.

The window is of the 'Thin Lens' shape, which means it has a flat surface on both sides, allowing for easy integration into optical systems. The uncoated nature of the window means it does not have any anti-reflective or other coatings, which can be beneficial in certain applications where such coatings may interfere with the desired optical performance.

This window is designed to work at a wavelength of 633nm, making it suitable for applications that use red light, such as certain types of lasers or optical imaging systems. The item data indicates that this window is in stock and available for immediate purchase, making it a convenient choice for those needing a high-quality silicon window.
