Product Details

Product Model: 61-6929-54
Product Brand: SIGMAKOKI CO., LTD.

Features

  • When thin, collimated white light is introduced into a prism, it is divided into wavelength components dep***ing on the difference in refractive index relative to the wavelength.
  • Dispersion prisms are ***d for dispersion compensation of oscillators in spectrometers and femtosecond lasers.
  • The wavelength dispersion is larger than that of a 45° prism, and the spectrum can be observed efficiently.
  • All three sides of the regular triangular prism are polished, so you can *** it from any side.
  • The DPSQ type is made of synthetic quartz and can be ***d in the ultraviolet range.
  • The DPTIH11 type has a large wavelength dispersion of refractive index and can observe the spectrum efficiently.
  • A prism holder (PLH) is provided for fixing the prism.
  • * Measured A dimension is slightly shorter since it includes chamfer.
  • * The tolerance is defined by the sides of the triangle formed by the slope and the two bases.
  • * Since the surface of the prism is not coated with anti-reflection coating, the transmittance loss is more than 11%. (However, in the case of unpolarized light)
