RW-28.6-14.3-3.18-C 28.6 x 14.3 mm N-BK7 Laser Grade Optical Window; t=3.18mm Uncoated

The RW-28.6-14.3-3.18-C is a high-quality optical window from CVI Laser Optics, designed for use in laser applications. This window is a flat, rectangular shape, with dimensions of 28.6 mm in width and 14.3 mm in height. It has a thickness of 3.18 mm, making it a thin lens suitable for various optical systems.

The window is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material, also known as Schott glass, is often used in laser applications due to its high damage threshold and low autofluorescence. The N-BK7 material ensures high transmission and low absorption across a wide range of wavelengths, making it suitable for use with a variety of laser sources.

The RW-28.6-14.3-3.18-C is designed for use at a wavelength of 633 nm. This wavelength is commonly used in helium-neon lasers, a type of gas laser that emits a bright red light. The window's design at this wavelength ensures optimal performance and minimal loss of laser power.

Notably, this optical window is uncoated. While coatings can be applied to enhance the window's performance, such as by reducing reflection or increasing transmission, an uncoated window can be advantageous in certain applications. For instance, an uncoated window can be used when broadband anti-reflection coatings are not required, or when cost is a significant factor.

The RW-28.6-14.3-3.18-C is currently in stock and available for immediate purchase. More information about this product can be found on the CVI Laser Optics website.
