MPF has a large variety of air and vacuum side accessories that are designed to work with ceramic-to-metal specifications. Coaxial plugs, multipin connectors, thermocouple hardware, in-vacuum cables, signal and power contacts, voltage standoff spacers can all be chosen to transmit your energy and data.
MPF has multiple ceramic-to-metal designs brazed and welded into 304 Stainless Steel 1” OD bolts. These bolts become compressed against the wall of the vacuum/pressure vessel using an elastomer style O-ring. These are typically used in High Vacuum deposition and coating applications where a quick disconnect mounting system is preferred. MPF offers these units in High Voltage, High Amperage, Multipin, Thermocouple, and Coaxial designs to meet all your system needs.
Beam Positioning Feedthrough (5)
MPF Products manufactures RF Coaxial connectors as an integral part of a Beam Position Monitor. These devices are used in High Energy Physics applications worldwide to gather characteristics about a beam’s size, shape, location, and intensity. These connectors are designed for UHV, high temperature environments with a capacitive button/antenna used for non-destructive diagnosis. MPF’s products are used in leading edge synchrotrons, accelerators, cyclotrons, and light source facilities around the globe.
We utilize 304SS, 304LSS, 316L, 316LN and titanium materials. Our units also have a flatness of Antenna-to-Housing (within .002”), concentricity of Antenna-to-Housing (within .002”), parallelism (within .002”), perpendicularity (within .002”) and have matched-impedance.
Coaxial Connectors (325)
MPF standard coaxial designs offer an electrical continuity through the inner most conductor while being electrically isolated from the vacuum flange and grounding system. Our coax connectors can also have a Floating Shield feature which offers additional isolation from the chamber ground. Our designs can be utilized with standard Mil Spec airside connectors, but we also offer Double End versions where a connector can be used inside the vacuum chamber. We offer numerous coaxial designations to fit varying requirements.
Crystal Sensor Feedthrough (12)
MPF offers a small variety of coaxial connectors combined with various stainless steel ¼ and 3/16 inches water lines for your thin film coating instruments. These can be mounted to standard conflat flanges and 1.00” inch base plate bolts.
Fiber Optic Feedthroughs (307)
MPF Fiber Optical Feedthroughs are designed for UHV applications with extremely low outgassing rates and excellent helium leak rates. The feedthroughs are designed to mate with industry standard connectors (FC/PC, FC/APC, and FSMA). These allow for high transmission and minimal insertion loss at interconnects. We offer four fibers in single mode and four fibers with broader range frequencies (multimode).
Multipin Connectors (189)
MPF manufactures a single header design with varying conductor qualities. These multipin’s are typically used for transmission of multiple electrical signals. In some applications they could also be used for low power requirements. The pin sizes can vary from .032” inches up to .142” inches supporting 1 amp per pin to 40 amps per pin. We offer these designs in Copper, Alumel, Nickel, BeCu, Stainless steel and Molybdenum conductor materials. We offer instrumentation circular Mil-C-5015 and Mil-C-26482 in addition to Instrumentation rectangular Sub D series 24308 and Micro D series 83513.
Power Feedthroughs (452)
MPF power feedthroughs transmit varying amounts of voltage and current from an external power supply to inside the vacuum chamber powering the customer application. MPF provides a wide variety of conductor sizes and alumina ceramic designs to satisfy the electrical system requirements. Our standard designs utilize copper, nickel, molybdenum, and stainless-steel conductors. We offer 500 volts to 100,000 volts with our standard designs.
RF Power Feedthroughs (8)
MPF has standard RF Power Feedthroughs. They are specifically designed for the transmission of Radio Frequency power into the vacuum environment using non-magnetic materials to reduce current induction. Our designs are water-cooled feedthroughs intended for use with grounded, closed-loop cooling systems with non-conductive coolants such as deionized water. Standard conductor options for these feedthroughs include copper, nickel and stainless tubes. These feedthroughs are mostly used induction heating, non-magnetic, and plasma generation applications.
Thermocouple Feedthroughs (360)
Thermocouple Connectors are commonly used in temperature measurement systems. They are designed to conduct a thermocouple’s voltage signal from inside the vacuum system to an external controller. MPF creates a hermetic bond between the alumina ceramic and various Thermocouple conductors such as Alumel, Chromel, Iron, Constantan, and compensating wire for Tungsten, Rhenium, Platinum, and Rhodium.
UHV Breaks (50)
MPF UHV breaks are tubular electrical isolators. Each design is comprised of a metal adapter hermetically bonded to each end of an alumina ceramic resulting in a voltage standoff from each side. All of our designs will yield a different voltage standoff depending on the length, wall thickness and inside diameter of the alumina ceramic.
UHV Viewports (167)
MPF Products, Inc. specializes in designing and manufacturing Optical components for scientific & harsh environment applications that require excellent atomic level hermeticity. MPF designs use UV and EUV grade Sapphire and Fused Silica to various metals.
MPF has over 175 standard designs on our website, while our engineering team has produced hundreds of specialty viewport designs over the last twenty years. Our extensive inventory levels of titanium and 316LN materials can easily translate into truly non-magnetic windows for your demanding environment.
Our Anti-Reflective (AR) and Indium-Tin-Oxide (ITO) Coated viewports have shipped globally for use in Laser Applications including KrF, XeCl, ND-YAG and Helium Neon lasers. We have also partnered with our customers to construct viewports for Differentially Pumped, Wedged, Brewster Angled, Large Viewing, Re-Entrant, Water-Cooled, Over Pressure and NIR/IR applications.
MPF Products Inc. does not approve the use of ultrasonic cleaning for any viewport. We ship our viewports UHV ready. You may simply blow off the glass to remove any contaminants with clean, dry air. For additional cleaning steps for particulates or contamination from other processes, please review our cleaning procedures at https://mpfpi.com/resources/category/uhv-viewport-cleaning-notes/
