Product Description Good Quality High Performance Sapphire Glass Optical Window Why choose sapphire glass? The uncoated sapphire window is suitable for harsh conditions, including environments subject to high temperature, high pressure, and strong vacuum or corrosive environments. Sapphire has high compressive strength and resistance to strong acid corrosion. Characteristics of Sapphire glass window: 1.Adapt to high temperature, high pressure or strong vacuum environment 2.High corrosion resistance 3.Transparency range from 170 nm to 5.5 µm 4.Very hard, more durable than standard optical glass Technical Information Material Properties Material properties including the transmission, refractive index, and hardness of the window substrate can be critical for deciding which window is the best choice for your application. The figure below highlights the transmission regions of the different materials Oplens® offers as windows. Types of Optical Windows Ultraviolet Windows This kind of optial windows-ultraviolet windows are often used with laser instruments or other applications in medical, industrial and defense areas. JUKA Optics can help determine the best substrates, UV coatings, and other optical properties and custom manufacture UV windows to best meet your specific requirements and applications. Anti-Reflective (AR) coating is available for one or both surfaces. Visible Windows Visible windows are designed for use in the visible spectrum: the type of light visible to the human eye. Visible windows are ideal for protecting optical systems and other optical components, imaging or display systems, or other applications. JUKA Optics can custom manufacture visible windows in a variety of shapes, sizes, and substrates for various optics applications, including those with extreme temperatures or other challenging conditions. AR coating is available for one or both surfaces. Infrared (IR) Windows Infrared windows are often used in FLIR, FTIR spectroscopy, medical systems, thermal imaging, or other optics applications within the infrared light spectrum. IR windows can help protect your employees and equipment. JUKA Optics can custom manufacture IR windows in a variety of shapes, sizes, substrates, and coatings for various infrared applications. AR coating is available for one or both surfaces. Product Parameters

Company Profile Oplens has been committed to providing customers with high-precision optical system solutions over 16 years, covering the complete manufacturing process from the design, processing and assembly of various optical components and mechanics.It occupies 10,000 square meters of modernized facilities with hundreds of equipments and instruments. More importantly, Oplens owns an excellent team of more than 200 experienced engineers and workers, who provide the best products and service to their both domestic and overseas customers. Processing Oplens equipped Precitech SPDT with Taylor Hobson PGI 3D profilometer. The results of the profilometer measurement system can be directly put into the diamond machine to provide positive compensation values for the machining of aspheric components. At the same time, curvature, surface flatness, roughness and other indicators can be quantified effectively and accurately. Testing Oplens equipped Zygos which work by producing a beam of laser light and transmitting it to the optic under test by way of a very, very accurate lens fitted to the Zygo. This is the key to the instrument's accuracy. As the light passes through this lens, which is not coated, it enables 4% of the light to be reflected back into the Zygo.
