Ceramic Laser Reflector for Pump Chamber

By -




High purity porous alumina ceramic of 99% Al2O3 content, used extensively for long-life Ceramic Laser Reflector. This material is sintered at high temperatures to achieve a controlled porosity.

Prime Features

  • Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity
  • 97% reflectance efficiency at 600-1000nm
  • Reflectance efficiency exceeds 95% across the wavelength range 400-1200nm (see curve)
  • Controlled porosity
  • Good thermal conductivity
  • High electrical resistivity

Physical properties

  • Color: White
  • Bulk density (fired): 3.1 g/cm3
  • Porosity (apparent), nominal: 22%
  • Flexural strength (ASTM C1161, 3-point): 170 MPa
  • Thermal expansion coefficient:
    200-500℃, 7.9*10-6/C
    200-1000℃, 9.0*10-6/C

Typical Applications

  • Pumping chambers for flash lamp and continuous-wave lasers using media such as Nd:YAG lasers,
    Alexandrite — low to high power, single or multiple lamp designs used for welding, cutting, marking, and in medical lasers.
  • Layered and segmented pumping chambers for diode-pumped lasers
  • Intense Pulse Light (IPL) applications for cosmetic surgery

Source: https://www.innovacera.com/news/ceramic-heater-coil-for-vaporizer.html Not every dry herb vaporizers are the same! Especially those used ceramic heating element. The ceramic heating element is a safety and healthiest option for dry herb vaporizers, so every vaper is preferred to choose those vaporizers that carry ceramic heating element. The proponents believe that the heating element is the core of the vaporizer and primarily dictates the experience of the taste. Let's more specific, when a vaper burns tobacco, marijuana, or hemp during traditional smoking to release the active component, whatever it's nicotine, CBD, or THC, they inhale the smoke. We all know that's not good for health. Rather than burning, Vaporizer heats the liquid, wax or even dry herb to release a vapour, and a vaper inhales the vapour without any damage to their lungs or throat. And why the ceramic heating element is becoming the core part of the vaporizer? It's mainly because: 1. Ceramic ...

BAN combines  Aluminum Nitride with Boron Nitride , a hybrid machinable Aluminum Nitride ceramic with excellent thermal conductivity, high strength, and resistance to thermal shock. Innovacera provides BAN, and it has very similar properties to SHAPAL material. SHAPAL is a trademark of Tokuyama Corporation.   These ceramics are used in various industries, including electronics, semiconductor manufacturing, aerospace, automotive and medical. BAN ceramics have properties that make them suitable for applications such as  heat sinks , heater substrates, semiconductor processing components, and optical equipment.   Material Advantages : High mechanical strength. High thermal conductivity. Low thermal expansion. Low dielectric loss. Excellent electrical insulation. High corrosion resistance–non-wetted by molten metals. Excellent Machinabilit–BAN can be machined to high-precision complex shapes. It has excellent sealing ability to vacuum and hasn’t given off much gas. High-...
