Chalcogenides have a narrow band-gap energy which results in special optical properties of chalcogenide glasses, such as high refractive index, infrared (IR) transparency, nonlinear optical properties, and reversible phase change from amorphous to crystalline. Chalcogenide glasses can be polished or machined into planar, spherical or other shapes for various applications.

These pumps are easy to use and require less care and maintenance than diffusion pumps. The small foot print, the lack of need to cool with water, the speed to reach the desired vacuum, the high purity of these pumps are other advantages compared to diffusion pumps. Using these pumps, the pumping speed can be constant with a good accuracy (One of the disadvantages of these pumps is their high price). Turbomolecular pumps can be used in the range of rough vacuum, high vacuum and Ultra-High Vacuum (UHV) with a constant pumping speed of up to 4000 liters per second.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] What is the GLAD Sputtering Technique? There are various techniques for increasing the quality of thin films deposited by vacuum coating methods. GLAD Sputtering (Glancing Angle Deposition) or OLA (Oblique Angle Deposition) is one of the most widely used techniques in the sputtering deposition process. GLAD method helps to achieve different microstructural architectures and increases the surface area of thin films. In the GLAD Sputtering, you could make an array of periodic microstructures to increase the surface sensitivity.

Plasma Cleaning | What is Plasma Cleaner?

Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] What is Plasma Cleaning? Surface cleaning using plasma is an economical way to clean specimens uniformly and securely through plasma treatment. Removal of contaminants from the studied substrates without affecting the overall properties of the material is one of the benefits of the plasma surface cleaning method. Plasma cleaning is widely used in the circuit industry, including cleaning the PCB board before coating and cleaning the lead frames during the packaging process. Plasma sample cleaning has significant advantages over other surface cleaning methods as it applies to a wide range of materials, is eco-friendly, residual-free, and effective in highly sensitive applications like cleaning medical equipment.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text css=""] Mass Spectrometer Leak Detector (MSLD) Helium Leak Detector (HLD), also known as the Mass Spectrometer Leak Detector (MSLD), is an instrument commonly used to find the location of the leakage and measure the rate of it in a system. Among several methods of leak detection, helium leak test is the most accurate one. [/vc_column_text][vc_column_text css=""] What is A Vacuum Chamber Leak? Ideally, the vacuum chamber should retain the vacuum after the pumps have been turned off. But in real systems, over time, system pressure increases. This increase in pressure can be due to the penetration of wall molecules (Outgassing) or due to leakage and penetration of molecules from outside into the system.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] What is Pulsed DC Sputtering? Pulsed DC Magnetron Sputtering is a physical vapor deposition method used to make thin films of various materials including conductors and insulators. It is especially preferable in reactive ion sputtering where the risk of arc discharge damage is high. The arc discharge is a result of charge accumulation on the target and is harmful to both the thin film and the power supply.
