X-Ray Windows

  • Do you have standard mounted beryllium windows?
    Yes, we have standard mounted beryllium windows available in conflat flanges.
    Design Guidelines for DuraBeryllium window mount
  • What sizes of AP windows are available?
    Our standard sizes are 10mm2, 30mm2, 50mm2, 80mm2, and 140mm2. We can also talk to you about custom sizes and geometry.

    Consult a Moxtek expert >
  • What’s the difference between your DuraBeryllium and AP windows?
    In most cases, you would use our DuraBeryllium windows to detect elements as light as sodium and our AP windows for elements as light as beryllium (Be).

  • What does DuraCoat do?
    DuraCoat is our patented corrosion prevention coating that increases the life of your window, especially if it’s exposed to humidity or other corrosive materials. For minimal transmission loss, we make DuraCoat with elements lighter than oxygen.

    Visit our DuraBeryllium product page >
  • What is DuraCoat Plus?
    DuraCoat Plus is a polymer film added on top of our standard DuraCoat that adds additional corrosion prevention and leak integrity.
  • Does DuraCoat Plus have DuraCoat as well?
  • Where is DuraCoat applied?
    Generally, you would apply DuraCoat to any exposed surface using a proprietary deposition process.
  • Can I epoxy directly to DuraCoat?
    Yes you can.
  • Where can I find transmission curves for your windows?
    On each of our X-ray windows product pages, we've included a downloadable datasheet with that information.
  • How do you measure the leak rate of your windows?
    On each of our X-ray windows product pages, we've included a downloadable datasheet with that information.
  • How do I design a window mount?
  • What are the health hazards associated with beryllium?
    Under normal conditions and intended use, our X-ray windows have no exposure limits, nor do they represent an inhalation, ingestion or contact hazard.

    Please reference our Material Safety Datasheet (MSDS) for conditions that could cause harmful exposure to beryllium.

    See Material Safety Datasheet >
  • Can I buy bare beryllium from Moxtek?
    We are capable of providing bare beryllium. However, for your window’s protection, we strongly recommend using DuraCoat.

X-Ray Detectors

  • Do you sell a Silicon Drift Detector?
    At this time, we only sell PIN detectors.

X-Ray Sources

  • Does Moxtek manufacture tubes with voltages higher than 40kV?
    Yes. We offer our 50kV MAGNUM X-ray tube.
  • Can I use your sources for imaging?
    Yes, and we've even got an X-ray Sources web page with more information.

    Visit our X-ray Sources page >
  • What target materials are offered on your source?
    Each X-ray source web page contains a downloadable datasheet with that information.

    Visit our X-ray Sources page >
  • Why would you need different targets—like tungsten and rhodium—on an X-ray source?
    For XRF, tungsten is often used for metal identification RoHs/WHEE. Likewise, Rhodium or silver is typically used for light element analysis, detection of aluminum, magnesium, sulfur, etc.

    Consult a Moxtek expert >
  • What are your X-ray spot sizes?
    Our MAGNUM source spot-sizes from 500 microns to 800 microns.

    Consult a Moxtek expert >
  • What are the dimensions of your available sources?
    For monoblocks:
    We have a 4W (max), 50kV (max) monoblock source that is as small as 6” (150mm) long by 1” (25.4mm) wide by 2” (51mm) tall.
    We have a 12W (max), 60kV (max) monoblock source that is as large as 6.5” (165mm) long by 1.35” (35mm) wide by 2.75” (70mm) tall.

    For cabled power supplies, the power supply boxes range as follows: We have a 4W (max), 40kV (max) power supply that is as small as 5” (128mm) long by 0.8” (21mm) wide by 2” (51mm) tall, cables running between 4” (102mm) and 11.5” (292mm).
    We have a 10W (max), 50kV (max) power supply that is as small as 5.7” (145mm) long by 0.9” (23mm) wide by 2.25” (57mm) tall, cables running between 4” (102mm) and 11.5” (292mm).

    The tube shields range greatly, typically between 1.125” (29mm) and 1.25” (32mm) in diameter, 2.18” (55mm) to 2.5” (64mm) long.

    Specific dimensions are available on our datasheets.
  • Does Moxtek offer the power supply for x-ray tubes?
    Yes. All Moxtek X-ray sources include the power supply.
  • What power supply controller do you recommend for Moxtek tubes?
    We recommend our FTC-200 X-ray Tube Controller. For more information, we’ve posted a lot about this product on its detailed web page.

    Visit our FTC-200 Tube Controller page >
  • Are Optional Ribbon Cable (ASM00362) and Optional 2-PIN Secondary Cable (ASM00364) delivered with the product?
    The Optional Ribbon Cable is included with each of our FTC tube controllers. Our 2-PIN Secondary Cable is included with our standard 50kV cabled units. At the customer’s request, we will deliver the Optional Ribbon Cable and or Optional 2-pin Secondary Cable separately.
  • How much radiation do your X-ray sources produce?
    At 40kV, our tungsten sources give off approximately 3.0x1011 photons/second/steradian/100µA. Our silver sources (also at 40kV) give off approximately 1.5x1011 photons/second/steradian/100µA.
