Interferometry is nothing but optical interference to carry out precise measurements of very small linear dimensions. NPL Flatness Interferometer is developed by the National Physical Laboratory of the United Kingdom. We will discuss this NPL Flatness Interferometer construction and working principle with help of a schematic diagram. Construction of NPL Flatness Interferometer The NPL Flatness […]
What is an Optical flat in Interferometry?
An Optical Flat is a glass claimed to be extremely flat on one or both sides. it will be used with monochromatic light to determine the flatness of other objects with the help of optical interference. The optical flat is the popular choice for measurement using the interferometry technique, a host of other instruments, popularly […]
How to design a Cylinder?
Have you ever wondered how to design a Cylinder?? I mean how the basic parameters such as diameter and thickness are set. We mostly see Cylinders in Internal combustion Engines, Compressors, and Hydraulic pumps. In all these cases the Cylinder will experience internal pressure caused by combustion in engines, air compressed by the piston in […]
Stresses in a Thin Cylindrical Shell
You must have seen heavy vehicles transporting fluids such as water/petroleum or steam boilers in some industrial plants etc. with a cylindrical structure called tanks or Pressure vessels. These Pressure vessels are used to store the fluids under the pressure. Since these fluids are stored under pressure, these may undergo a state of change inside […]

Solex Pneumatic Comparator
A comparator is a precision instrument used to compare the Dimensions of a given working component with the actual working standard. There are different types of comparators are available. Solex Pneumatic Comparator is coming under the Pneumatic Comparators. Let us discuss this in detail. Solex Pneumatic Comparator Solex Air Gauges Ltd. is one of the biggest and most popular pneumatic comparators […]
What is Interferometry in Metrology?
In the previous article, we have discussed what is Optical Interference, in this article we are going to discuss Interferometry in metrology. In simple words, Interferometry is nothing but the use of optical interference to carrying out precise measurements of very small linear dimensions. Interferometry in Metrology Due to the Optical interference of two or […]
What is Optical Interference?
Optical Interference is an effect that can occur when two or more light beams are superimposed. We knew that a ray of light is composed of an infinite number of waves of equal wavelength. the value of the wavelength determines the colour of light. For the sake of simplicity, let us consider two waves, having […]
What is an Optical Square in Metrology?
In the previous article, we have discussed the different Optical Measurement Techniques, the first one is the Tool Maker’s Microscope, the second one is the Profile Projector, the third one is this optical square. In this article, we are going to discuss briefly Profile Projector. Optical Square An optical square is useful in turning the […]
What is Tool Maker’s Microscope in Metrology?
We generally utilize microscopes in science and medicine. It is also a metrological tool of the most fundamental importance and the greatest integrity. The Holmarc’s Tool maker’s microscope is a multi-functional measuring instrument used in metrology for inspection and measurement of miniature mechanical and electronic parts and tools. Tool maker’s microscope provides a high degree of magnification, and […]
What are the Optical Measurement Techniques in Metrology?
An Optical measurement device is made up of Optical means. We are familiar with the most common applications of optics, namely Microscopes. Chemists, Biologists and engineers use various types of microscopes. The main function of the microscope is that, for the visual magnification of small objects to a high degree with an additional provision for […]

What are Aramid Fibers? | Kevlar Fibers
Aromatic Polyamide, also known as Aramid fibers are a class of heat-resistant and strong synthetic fibers. In this article we will discuss more details on the Aramid fibers. Aramid Fibers Aramid Fibers are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in bicycle tires, marine cordage, marine hull reinforcement, […]
What is Carbon Fiber? | Graphite Fiber
Carbon fiber is also sometimes called as the Graphite Fiber. It is an advanced fiber material, Synthetic, and inorganic in nature. Carbon Fiber History In 1860, Joseph Swan produced carbon fibers for the first time, for use in light bulbs 1879 when Thomas Edison baked cotton threads or bamboo silvers at high temperatures, which carbonized […]
What are the different types of Glass Fiber?
Glass fibers are the advanced fibers which are synthetic fibers and inorganically prepared. Fibers are used as reinforcement in the Composite materials. Glass Fiber is one of the most common advanced fibers in the composites industry. We have discussed the different types of Glass Fiber in this article. Types of Glass Fiber Depending upon the […]
What is the difference between Heat and Temperature?
Have you ever thought that the heat and the temperature are the same? The answer is no. Heat and temperature are related to each other but are different concepts. In this article, we will understand how they are interconnected. Heat vs Temperature When two bodies of different temperatures bring them into contact with each other, […]
What is a Reinforcement and Matrix in composites?
The word “composite” means “consisting of two or more distinct parts”. Thus a material having two or more distinct constituent materials or phases may be considered to be a composite material. Reinforcement and the matrix are the two phases of the composite material. However, we recognize materials as composites only when the constituent phases will not […]
What is a Composite material? | Advanced Composites
The word “composite” means “consisting of two or more distinct parts”. Thus a material having two or more distinct constituent materials or phases may be considered to be a composite material. However, we recognize materials as composites only when the constituent phases will not dissolve into one another and have significantly different physical properties, and […]
What is Product Teardown process?
In the course of Product design and the development, Product Teardown is the process of taking apart a product to understand it and to understand how the company making the product succeeds. Let us discuss more detail on this topic. Product Teardown Before a product to be evolved to the next stage/generation, the current version […]
Function Analysis and System Technique – FAST diagram
To analyse the function of a product, service or process can be done with the Function tress techniques. FAST Diagram Method and the Subtract and Operate Procedures are the two techniques in functional trees method.
