Abbe number calculator 
The Abbe number, or V-number or constringence of a transparent material, is a measure of the material's dispersion (variation of refractive index with wavelength) in relation to the refractive index. A calculator created by Mikhail Polyanskiy using the optical refractive index data from his web database at RefractiveIndex.INFO that covers many glasses, crystals, plastics, liquids and more.

Advanced critical angle calculator 
The critical angle is the angle of incidence above which the total internal reflection of an incident ray of light occurs when the light passes from one optical medium into another. Optical properties are used from the online Refractive index database at RefractiveIndex.INFO for a wide range of materials including glasses, crystals, liquids, liquid crystals and some gases, created by Mikhail Polyanskiy .

Brinell Hardness Number Calculator 
The diameter of the impression is the average of two readings at right angles and the use of a Brinell hardness number table can simplify the determination of the Brinell hardness. A well structured Brinell hardness number reveals the test conditions, and looks like this, "75 HB 10/500/30" which means that a Brinell Hardness of 75 was obtained using a 10mm diameter hardened steel with a 500 kilogram load applied for a period of 30 seconds

Calculator for Conversion of Vickers Hardness Number 
There is now a trend towards reporting Vickers hardness in SI units (MPa or GPa) particularly in academic papers. Unfortunately, this can cause confusion. Vickers hardness (e.g. HV/30) value should normally be expressed as a number only (without the units kgf/mm2). Rigorous application of SI is a problem. Most Vickers hardness testing machines use forces of 1, 2, 5, 10, 30, 50 and 100 kgf and tables for calculating HV. SI would involve reporting force in newtons (compare 700 HV/30 to HV/294 N = 6.87 GPa) which is practically meaningless and messy to engineers and technicians. Gordon England
