Hace 5 días · Polishing with the bonnet head linearly 30 mm distance, and measured the lens surface after the experiment through ZYGO Verifire™ Fizeau interferometer, and captured the line segment cross-section. If the polishing pad is grooved, the contact between the groove and the workpiece may change the TIF shape from smooth to sharp, which have either a Gaussian or trapezoidal shape.

Hace 1 día · In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light).The opposite change, a decrease in wavelength and increase in frequency and energy, is known as a blueshift, or negative redshift.The terms derive from the colours red and blue which form the extremes of the visible light spectrum.
Hace 5 días · Determining the surface quality of a critical component, the deviation from the intended shape whether ?at, spherical, etc.is crucial to high-precision manufacturing. Traditional methods consist of an interferometer, for example a Twyman-Green interferometer (pictured below) that compares the test optic to a reference.
