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.

High voltage vacuum relays by INNOVACERA are essential components in various advanced electronic systems, including airborne, mobile, and marine communication devices. Their robust design ensures reliable performance in demanding applications such as radio frequency (RF) circuitry, antenna switching, and heavy-duty power supplies. They are also widely used in environments requiring precise and efficient switching mechanisms. Vacuum serves as the ideal dielectric medium for high-voltage relay operations due to its outstanding electrical properties. It offers: Exceptional voltage breakdown strength. Rapid recovery times of up to 10 kV per millisecond. A completely inert environment for switching contacts, ensuring no oxidation or degradation over time. These characteristics make vacuum relays highly efficient, durable, and reliable for high-performance switching tasks. Relay Types INNOVACERA offers two primary designs of vacuum relays to cater to diverse application needs: Clapper Type R...

Why Metal And Ceramic CO2 Laser Tubes Are The Most Chosen For High-Performance CO2 Lasers

By -

  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 gasses 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 gasses 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, depe...
