UHV Overview Ultra-high vacuum (UHV) is a vacuum level where the gas pressure is so low that tiny leaks, surface contamination, and outgassing from materials can control how the system behaves. In most engineering contexts, UHV means pressures at or below about 10⁻⁹ torr (~10⁻⁹ mbar), far below what typical
Hermetic sealing is the science and engineering practice of creating a long-term, gas-tight barrier that protects sensitive components from moisture, gases, contaminants, and pressure changes. True hermeticity is often the difference between systems that operate reliably for years and systems that degrade prematurely because the outside environment slowly reaches the
Vacuum feedthroughs, flanges, and hermetic components are where most real-world vacuum systems either succeed or fail over time. These are the parts that must create true hermetic seals between the inside of a chamber and the outside environment while still letting power, signals, fluids, and light pass through the wall.
To avoid coating and/or window damage with laser applications, one needs to consider several parameters. The most fundamental consideration is the mode of laser operation: Pulsed vs. Continuous Wave (CW). Pulsed lasers deliver discrete energy packets, while CW beams supply continuous power. Pulsed The most significant parameter for pulsed lasers
Laser-induced-damage thresholds (LIDT’s) with various types of vitreous silica at 1064, 532, 355, and 266 nm are investigated. To read the full report, use the download link below.
All standard part numbers and special assemblies are 100% Helium Leak tested and guaranteed to Ultra High Vacuum (UHV) standards. Helium mass spectrometer leak detection is the most common form of leak detection used to qualify assemblies for high vacuum and ultra-high vacuum applications. Helium is one of the smallest
Scope: Excerpted from ASTM E498/E498M-11 This practice covers procedures for testing and locating the sources of gas leaking at the rate of 1 × 10-8 Pa-m3 /s (1× 10-9 Std. cm3 /s) or greater. The test may be conducted on any object to be tested that can be evacuated and
