GB/T 22061-2008Microscopes -- Reference system of polarized light microscopy (English PDF)

GB/T 22061-2008 is the English-translated version of 显微镜 偏光显微术的参考系统.

GB/T 22061-2008 — This standard specifies the microscope and all rotating and moving the adjustment mechanism of attachment on the reference system, in order to consistent measurement process.

This standard focuses on the polarization parameters and test accessories, such as rotating stage microscope, polarizing element and compensator. Principle 2 Under pressure, temperature and wavelength constant, anisotropy, asymmetric and non-absorbing crystal optical properties, can be folded with a triaxial Reflectance ellipsoid described.

The length of the axle ellipsoid shaped by the principal refractive index alpha crystal form beta and gamma given shape. After any of the refractive index ellipsoid and ellipsoidal Planar body centers are generally shaped shaft length alpha and gamma-shaped oval.

By definition, a relationship with each other. like alpha<= like alpha<= like beta<= like gamma<= like gamma. All provisions in the polarization direction of observation is the reference direction of the highest refractive index-like gamma.

NOTE. To emphasize | like gamma | > | shaped alpha |, subscript usually gamma and alpha instead of gamma 'and alpha'. Uniaxial refractive index ellipsoid is a spheroid, and provides shape and form omega epsilon for two spindles, which shape and form omega epsilon substituting Table ordinary ray and the direction of vibration is very light.

The latter is a rotary axis direction, defined as follows. Shaped like alpha = beta = gamma = form omega != shaped like epsilon (n), shaped like beta = gamma = omega != shaped like shape alpha = epsilon (negative) that is.

If epsilon-like shape is greater than omega, compared with a positive uniaxial crystal; on the contrary, is negative uniaxial crystal. 3 the direction of rotation and displacement of the reference system (see Figure 1)
