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. Typical applications Ceramic Reflectors For Beauty and IPL Applications Ceramic Reflectors For Diode-pumped Solid-state Lasers Ceramic Reflectors For Lamp-pumped...

Boron Nitride Ceramic Insulator For High Temperature Furnace

  High temperature furnace designs contain heating elements made of carbon, tungsten or molybdenum. When the operating temperature of the high temperature furnace is significantly higher than 1500 ° C, the elements are electrical insulated from the furnace sides using aluminum oxide ceramics.   With the development of technology, more and more companies need high temperature electrical furnaces with shorter production cycles and faster heating and cooling speeds. These oxide ceramic insulation parts are easily subject to failure of components due to high pressure, which increases the downtime of the furnace.   Compared with traditional aluminum oxide materials, the working life of ceramic components made of hexagonal  boron nitride (BN)  is much longer. For thermal processes at extremely high temperatures and vacuum or inert conditions,  boron nitride ceramics  are often the only feasible solution. Boron nitride ceramic material max using temperature i...

  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...
