Germanium Plano-Convex (PCX) Lenses feature precision diamond turned surfaces making them ideal for a variety of infrared applications, including thermal imaging, infrared spectroscopy, and remote sensing. Germanium (Ge) is popular for its high index of refraction, broad transmission range, and rugged mechanical properties. These lenses are available in 25 and 50mm diameters, uncoated, or with multiple broadband coating options.
Germanium (Ge) material feature high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these germanium windows for sufficient transmission in the region of interest. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these germanium windows should be used at temperatures below 100°C. Germanium`s high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems.

Application and structure of CQB-G high temperature magnetic centrifugal pump
I. Product use: CQB-G-type high temperature magnetic centrifugal pump for petroleum, chemical, pharmaceutical, metallurgy, electroplating, environmental protection, food, film and television printing, water treatment, defense and other industries, is the transport of high temperature flammable, explosive, volatile , Toxic, rare precious liquid and a variety of corrosive liquids ideal equipment. It is suitable for liquids without hard particles and fibers whose working pressure is less than 1.6MPa, temperature is less than 280 ℃, density is not more than 1840kg / m3 and viscosity is not more than 30cm2 / S. Two. Product Overview: CQB-G-type high-temperature magnetic centrifugal pump is usually motor, magnetic coupling, water cooling device and corrosion-resistant centrifugal pump four major components, the main feature is the use of magnetic coupling to transmit power. When the motor drives the outer magnet of the magnetic coupling to rotate, the magnetic flux passes through the gap and the isolation sleeve and acts on the inner magnet so that the pump rotor rotates synchronously with the motor to transmit the torque without mechanical contact. At the pump's power input, there is no dynamic seal and no leakage because the fluid is enclosed in a stationary isolation sleeve. Magnetic coupling magnetic materials using high temperature rare earth permanent magnetic materials, can withstand 280 degrees below the high temperature medium and maintain a strong magnetic torque. A water cooling device is installed between the motor and the magnetic coupling to prevent the heat from pumping the high-temperature medium from being conducted to the motor so as to keep the normal operation of the motor so as to achieve a leak-free transmission of the high-temperature medium.
