• When thin, collimated white light is introduced into a prism, it is divided into wavelength components depending on the difference in refractive index relative to the wavelength.
• Dispersion prisms are used 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 use it from any side.
• The DPSQ type is made of synthetic quartz and can be used 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)
