constringence. A measure of the dispersion, or the way in which the refractive
index of an optical material varies with wavelength, symbol, r. It is given by:
where m486 is the refractive index at 486 nm (Balmer H-b line), m5iw is the
refractive ...

Constringence. In an optical medium, the Abbe number is defined as the inverse
of its dispersive power; that is, it represents the relative importance of refraction
and dispersion. There are two common definitions based on the use of different ...

The degree to which the refractive index varies with wavelength is called the
dispersion and is measured by the constringence, ν ν μ μ μ = − − 589 486 656 1 (
1.38) where μλ is the refractive index at wavelength λ. The three wavelengths that

Choosing and Using a Refracting Telescope
The Abbe number, also known as the V-number or constringence of a glass
material, is a measure of the glass's dispersion (variation of light bending with
wavelength) in relation to the refractive index. The Abbe number V of a material is
...

Here, v is the constringence of the glass, that is the reciprocal of its dispersive
power. Thus constringence is expressed by (nd — — ne). In the varieties of
optical glass available prior to 1886, a higher index was always accompanied by
a lower ...

A prism surface length of 2 cm is used and a precision of ±0.1 mm in prism
translation is assumed. If, for any spectral interval (Xi— Xi), the corresponding
constringence of a substance lies above the A E curve for the appropriate A, then
no ...

The first three numbers are the refractive index at a wavelength of 587.56 nm
minus 1 and the second three numbers are the first three digits of the Abbe
number or constringence at that wavelength. The Abbe number v is given by the
following ...

Dictionary of Pure and Applied Physics
The larger the constringence, the lesser the chromatism. The inverse of the Abbe
number is the dispersive power. Abbe sine condition (1) For an optical system, if
one considers the object and image planes perpendicular to the optical axis, ...

It has been customary in the past to specify the properties of an optical glass by
