WebLens doublets are also known as achromatic lenses or achromats for short, derived from the Greek terms a meaning without and chroma meaning color. This simple form of correction allows the image points at 486 nanometers in the blue region and 656 nanometers in the red region to now coincide (Figure 1(b)). An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. Wavelengths in between these two then have better focus error than could be obtained with a simple lens.

WebThe line from the achromatic point W intersects the chromaticity diagram boundary at a saturated nonspectral purple-red at P. The dominant colour designation is then obtained by extrapolating the line in the opposite direction to a saturated spectral colour and is given as “complementary dominant wavelength 495 nm,” or 495c. WebPivot Point Meaning. A pivot point is a technical analysis indicator commonly used in financial markets to determine potential support and resistance levels for an asset’s price movement. It is calculated based on the previous trading day’s high, low, and closing prices. It helps traders figure the market trends at various time points dutch chip machine maker
