In transporting fluids such as water, steam, gases, oil, and chemicals, pipes are used. Designing a pipe with basic parameters such as the diameter and thickness of the pipe is explained in the previous article. While designing these pipes the length can be limited, there must be a way to join them to achieve suitable […]
What are the different Reticles in Metrology?
First of all, What is a Reticle? A Reticle is a Graticule that turns the microscope into a measuring device in Metrology. On the eyepiece of the microscope, there are the graduated reference lines are etched to take measurements, these are the Reticles. In this article, we are going to discuss the different Reticles with […]
What is Laser Interferometer?
Interferometry is nothing but the use of optical interference to carrying out precise measurements of very small linear dimensions. Laser Interferometer is one of the interferometers which uses laser means and electronic controls to carry out the inspection of machine parts for straightness, parallelism, and flatness, and measurement of very small diameters, among others, and also […]
Apple MacBook Air M1 Review
On November 10, 2020, Apple released the MacBook air with their own chipset so-called M1 based on ARM architecture. Previously apple used the intel chips built on the x86 architecture on the MacBooks. Here is the quick unboxing video showing the first look at the Apple Macbook Air with an Apple silicon M1 chip. Is […]
How to design a Pipe to transfer fluids?
Pipes are used to transporting the fluids such as water, steam, gases, oil and chemicals. So these pipes may undergo internal pressure for some applications and for some not. Many of us wondered about the pipes that we see to transport the fluids that are going to withstand the pressure exerted by the fluid or […]
How to design a Hydraulic Press?
Have you ever wondered how to design a Hydraulic Press?? We use Hydraulic Press for many applications from a manufacturing point of view to compacting. In this article, we will understand how to design a hydraulic press by finding out the necessary parameter such as the diameter of the ram, vertical columns, and Hydraulic cylinder […]
Stresses in Thick Cylindrical Shell
We have already discussed the different types of pressure vessels previously. The thick cylinder is one of the types of Cylindrical shells which is subjected to very high internal pressures for many applications such as Gun Barrels, Hydraulic cylinders, and pipes. In these applications, the wall thickness must be made thick to accommodate the high […]
How to use Pitter–NPL Gauge Interferometer?
Interferometry is nothing but optical interference to carry out precise measurements of very small linear dimensions. Pitter–NPL Gauge Interferometer is one of the interferometers in metrology used for determining actual lengths of slip gauges. We will discuss this Pitter–NPL Gauge Interferometer construction and working principle with help of a schematic diagram in this article. As we mentioned above, […]
How to use NPL Flatness Interferometer?
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 Optical Square in metrology. Optical Square An optical square is useful in […]
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 […]
