Vacuum Gauge Anode Assembly

By -


INNOVACERA provides precision anode assemblies designed for INFICON MPG400 / MPG401 cold cathode vacuum gauge repair and refurbishment applications.Manufactured with high purity alumina ceramic insulation, precision metallization and vacuum brazing technology,the assembly delivers reliable high voltage insulation, vacuum compatibility and stable electrical performance.


Technical Features

1.Built for high voltage vacuum environments.
2.Precision electrode alignment for stable ionization.
3.High voltage insulation for 2-4 kV DC operation.
4.Vacuum compatible materials for low outgassing conditions.
5.Hermetic ceramic to metal sealing by metallization and vacuum brazing.
6.Excellent electrical stability and long service life.
7.Precision concentricity control for field symmetry.

Why the Anode Assembly Is Critical

The anode assembly is a key electrical discharge control component in cold cathode vacuum gauges. Operating under 2-4 kV DC high voltage, it creates the electric field required for ionization. Precision alignment and insulation stability directly affect measurement accuracy and gauge reliability.

Ceramic Reflectors

Source: https://www.innovacera.com/news/ceramic-reflectors.html Our ceramic reflectors work particularly well in Ruby and Nd:YAG laser pumping chambers and can be a highly cost effective alternative to metal coated reflectors. They are also extensively used as reflectors in housings for high intensity lamps. Ceramic reflectors can be glazed both inside the cavity and the out surface using a highly reflective glaze that seals the ceramic against ingress of cooling fluids that may alter the refractive index, introduce impurities and reduce reflectance and efficiencies. Glaze can also act as filters and our yellow glazed reflectors have been used successfully in certain applications. The visible yellow colour is complementary to the spectral colours violet and indigo and effectively absorbs these wavelengths up to around 450 nm.

  The laser tubes usually used in CO2 laser machines are categorized into DC glass、RF metal tubes and ceramic tubes. But Metal-sealed lasers are the most proven technology on the market for high-performance CO2 lasers. Metal laser tubes are sealed metal chambers made of metal and ceramic. Metal is typically stainless steel or other durable alloys and ceramics are usually alumina; they are brazed to form a feedthrough of up to 1.0 x 10 -10 atm-cc/sec. The tube is filled with a specific mixture of gases in the ratio of 1:1:8, typically: Carbon Dioxide (CO2): Nitrogen (N2): Helium (He). The metal and ceramic laser tubes use a technique called “radio frequency” to stimulate the gases to produce the beam. Using RF has advantages over DC voltage, including lower energy consumption, better control of the engraving process, and longer life, resulting in a higher-quality laser beam output over a longer period of time. Metal and ceramic laser sources can be air-cooled or water-cooled, depend...
