WebThe 4 Most Common Spectrometer Applications. Spectroradiometers are used to separate, quantify, and analyze the spectral characteristics of a light source, providing industry-specific insights based on a light’s wavelength intensities or frequency. Spectroradiometers use a grating to split light into wavelengths of different bandwidths and ... WebA spherometer is a tool used to measure spherical curvatures. They work great for measuring the radius of curvature (ROC) of your mirror as you progress through the grinding process, allowing you to determine if your ROC is getting longer or shorter. You can also use one to measure the radius of curvature of an unknown surface.

WebThe spherometer used for measuring radius of curvature of spheri-cal surfaces is explicitly based on a geometric relation unique to circles and spheres. We present an alternate approach using coordinate ge-ometry, which reproduces the well-known result for the spherometer and also leads to a scheme to study aspherical surfaces. We shall also brie
A spherometer is an instrument used for the precise measurement of the radius of curvature of a sphere or a curved surface. Originally, these instruments were primarily used by opticians to measure the curvature of the surface of a lens.
