Description
Our premium optical components are meticulously crafted to meet the highest standards of precision and quality. These components are available in a variety of materials, including ZnSe, ZnS, Ge, Silicon, CaF2, Sapphire, Fused Silica, SF, and BK7, each offering unique properties suitable for diverse optical applications. With a uniform diameter tolerance of +0.0''/-.010'' and thickness tolerance of ±.010'', these components ensure reliable and consistent performance across all uses.
The surface quality of these optical components is exceptional, with a remarkable surface figure tolerance of less than 3 arc minutes and a surface quality rating of 40/20 or better, depending on the material. This high level of precision ensures that the components deliver optimal performance with minimal optical distortion. The components also feature a wedge surface figure of λ/40 at 10.6µm for ZnSe, ZnS, Ge, and Silicon, and λ/4 for CaF2, Sapphire, Fused Silica, SF, and BK7, further enhancing their optical clarity and efficiency.
Our optical components are designed to achieve superior transmittance, exceeding 85%, with a CA chamfer ranging from .01'' to .03'' at 45°. This ensures that light passes through with minimal loss, making them ideal for high-precision optical systems. The components are suitable for various applications, including spherical lenses, cylindrical lenses, and flats/plano surfaces, offering versatility for different optical designs.
The coatings available for these components are tailored to meet specific wavelength requirements, ranging from narrowband IR (2µm to 20µm) to broadband VIS/NIR applications. With anti-reflective coatings achieving reflectance as low as ≤0.25% and laserline coatings providing reflectance up to ≥99.7%, these components are optimized for maximum performance in demanding optical environments.
Please note that the specifications provided are intended for reference only and may vary based on dimensions and other customer-specific requirements. Our team is dedicated to providing customized solutions to meet the unique needs of each application, ensuring that our optical components deliver unparalleled performance and reliability.

Frequently Asked Questions
The Parallel Windows are designed for applications in which angular deviation of the transmitted beam must be kept as small as possible. Misalignment errors are also minimized when the window is repeatedly inserted and removed.
The diameter tolerance is +0.0''/ -.010'' and the thickness tolerance is ±.010''. The surface figure is λ/40 @ 10.6um and the surface quality is 40/20 > 85%. The wedge is < 3 arc min and the CA Chamfer is .01'' - .03'' @ 45°.
Parallel Windows are similar to Plane Windows, but with parallel surfaces. They are well suited for applications in which angular deviation of the transmitted beam must be kept as small as possible.
Round, square, and rectangular windows are available in a wide range of size and shape specifications. Materials available include ZnSe, ZnS, Ge, Si, Cleartran, and Chalcogenide Glass.
