  Quartz Crystal Wave Plate

  SURUGA SEIKI

  A birefringent element that applies phase contrast​to incidence light. Made by cutting a uniaxial quartz crystal along a plane that is parallel to the crystal axis.
  
  [Features]
  · A birefringent element that applies phase contrast​to incidence light. Made by cutting a uniaxial quartz crystal along a plane that is parallel to the crystal axis.
  · It is structured from two quartz crystal plates adhered together with their crystal axes orthogonal to each other. This helps reduce the impact of phase contrast​due to changes in temperature.
  · Both the 1/4 wave plate and the 1/2 wave plate have narrow band anti-reflection film applied on both sides.
  · The birefringence amount of a crystal varies depending on the wavelength. Its phase contrast​also changes.
  · Therefore, to obtain a phase contrast​of λ/4 or λ/2 using wave plates, it is necessary to select according to the wavelength used. A prescribed retardation cannot be obtained in other wavelength ranges.

  Polarizing Plate

  SURUGA SEIKI

  [Features]
  · A polarizing plate is a polarizer that can obtain linearly polarized light by making use of the dichroism of polymers.
  · Structured with a polarizing film sandwiched by transparent plastic sheets.
  · The extinction ratio is lower in comparison to polarizers (Glan-Thompson, etc.) which make use of birefringence and they are not adequate for high precision measurements. However, they are extremely useful for simple optical experiments from the perspective of them offering excellent affordability.
  · The element does not contain a mark to indicate the transmission axis.

  Wave Plate

  SURUGA SEIKI

  A multi-order wave plate structured from a birefringence polymer sandwiched between two glass substrates. Ideal for basic polarized light experiments and experiments that do not require high levels of precision.
  
  [Features]
  · Ideal for basic polarized light experiments and experiments that do not require high levels of precision as they are more affordable than quartz crystal wave plates.
  · The birefringence of a wave plate varies depending on the wavelength of the light. Its phase contrast​also changes.
  · Therefore, there are some cases where the wavelength plate will not be effective in wavelengths other than the wavelength to be used.
  · An anti-reflection film for the wavelengths used has been applied on the front and the back surfaces of the wave plate.
  · Do not use in high temperature environments or with high energy lasers.
  · The phase contrast​may change due to changes in temperature.
