At MOK Optics Co LTD, we specialize in manufacturing step optical windows, including customized shapes with anti-reflective (AR) coatings tailored to your needs. Step windows are particularly beneficial in high-pressure environments, offering significant advantages over traditional optical windows.
What Are Step Windows?
Step windows are optical components characterized by a step ground into the edge or length of the glass, often produced according to specific customer designs.
Applications of Step Windows:
Step windows find excellent utility in viewports, pressure chambers, vacuum systems, and assembly processes. They can be crafted with step-ground or angled cones, enhancing their versatility and ease of handling.
Materials Used for Step Windows:
The choice of material for step windows depends on various factors such as optical performance, chemical properties, physical attributes, thermal behavior, and cost. Common materials suitable for step windows include N-BK7 (H-K9L), Fused Quartz, Borosilicate, and Sapphire, each offering unique benefits.
Key Design Parameters for Step Windows:
Materials:
Select the most suitable material based on the desired optical and mechanical properties.
Shape:
Consider shapes like round, square, or rectangular, with round step windows often being the most cost-effective choice.
Chamfer:
Include chamfers for chip removal, protection, and inner groove considerations.
Thickness:
Determine the minimum thickness required for your specific pressure conditions, optimizing performance while reducing weight and size.
Optical Coatings for Step Windows:
AR coatings are commonly applied to step windows to minimize reflection and enhance transmission efficiency. We offer a range of multiple anti-reflection coating options suitable for ultraviolet (UV), visible, and infrared (IR) wavelengths, ensuring optimal optical performance in diverse applications.
