Abstract
In order to furnish an optical component and a phase contrast microscope which can indicate difference of phases of a specimen including information of frequency and color, at least two optical mediums are arranged side by side so that a constant difference of the phases is generated.
Claims6
An optical component including an input surface which receives light beams of at least two wavelengths, and an output surface which outputs the light beams after changing a phase of the received light beam, comprising
- an optical medium body which includes at least two optical mediums arranged side by side between said input surface and said output surface,
- said optical medium body including
- a first optical medium portion which outputs each of said light beams of at least two wavelengths after changing a phase thereof according to the wavelength,
- a second optical medium portion which outputs each of said light beams of at least two wavelengths after changing a phase thereof according to the wavelength so that difference between a phase of the light beam outputted from said first optical medium portion and a phase of the light beam outputted from said second optical medium portion is approximately constant.
