monocrystalline Al2O3 sapphire step lens sapphire glass windows
Sapphire step windows are either windows or plates ground with a step into the edge or length of the glass. This step can allow for rings or sealant for useful for sealing into housing or mechanical assembly. The step windows are made from a wide range of materials including BK7, Fused Quartz, Borosilicate and Sapphire. In fact all materials can be engineered in this way subject to thickness. Additional bevels can be ground to the step for assembly and handling. Angles can also be produced to create angled cones or an angled ground step
ZMSH stock step windows to various designs and can custom make them to additional shapes with AR coatings.
- Sapphire physical parameter
Sapphire material has high hardness (Moths 9), high melting point (2050℃) and good thermal stability, with wear resistance, corrosion resistance characteristics. And in the infrared spectrum, it has a high transmission rate, can be used in the wavelength range of 200 nm - 450 nm.

ZMSH Optics ‘C’ cut axis Sapphire windows and plates are cut to the optical axis perpendicular to the plane of the crystal, this is known as ‘C’ cut, ‘Z’ cut or 0° plane cut Sapphire. This material is better suited for highly optical and mechanical applications due to random being moderately birefringent. Extremely hard and has a good transmission from the ultraviolet to the mid infrared ideal for optical and high demanding mechanical applications. These windows and plates are used in analytical, medical instruments, camera systems, optical instruments and industrial applications.
Our Optics stock Sapphire windows & plates ‘C’ cut axis are stock in many sizes with the option to custom make to a desired specification including AR coatings.
