Sapphire optical window customizable size high-temperature crucible surgical imaging

Product Description:

Engineered for extreme environments, this transparent sapphire optical window features a 2cm (20mm) diameter with customizable thickness to meet specific pressure or weight requirements. Fabricated from 99.99% pure single-crystal Al₂O₃, it offers a broad transmission range from UV to mid-infrared (150nm to 5500nm).

With a Mohs hardness of 9, it provides unrivaled scratch resistance and structural integrity, making it ideal for high-pressure viewports, aerospace sensors, and semiconductor processing chambers. Its exceptional thermal conductivity and 2040°C melting point allow for stable performance in intense heat. Whether used in medical lasers or deep-sea exploration, this window maintains optical clarity against corrosive chemicals and abrasive debris. Standard finishes include S/D 60/40 or 40/20, ensuring precision for high-end industrial and scientific instrumentation.

Key Features:

Thermal Resistance:Withstands temperatures above 2000 °C, maintaining stability in extreme heat(continuous use around 1500°C and thermal cycling environments.

Hardness & Durability: Mohs hardness of 9, offering outstanding resistance to scratches, wear, and mechanical damage.

Chemical Stability: Highly resistant to acids, alkalis, and corrosive gases, ensuring long service life in harsh chemical environments.

Fully Customizable Dimensions:Available in customized outer diameter, inner diameter, length, and surface finish touch to meet specific application requirements.

Applications:

1.In analytical chemistry, these windows are used in FTIR or UV-Vis spectroscopy cells. The 1.25mm thickness provides the necessary structural rigidity to withstand high pressures during liquid sampling. Because sapphire is chemically inert, it allows for the analysis of corrosive acids and bases that would destroy standard glass.

2. In industrial furnaces or vacuum chambers, this specific window size acts as a durable viewport for infrared temperature sensors. The 20mm diameter offers a sufficient field of view, while the sapphire material transmits heat signatures in the mid-infrared range flawlessly, even when exposed to temperatures exceeding 1000°C.

3. The 20mm diameter is a standard size for protective lens covers in specialized medical imaging. Sapphire's extreme hardness ensures the window remains scratch-free during surgical procedures or sterilization. Its biocompatibility and 1.25mm thickness make it a robust barrier for sensitive internal optics against bodily fluids and physical impact.
