Abstract
An optical microscope, which has a light source, for observing a sample by illuminating light from the light source on the sample includes a second light source that is different from the light source and is insertable/removable in/from the optical path of the optical microscope. The second light source is configured to have the peak of an emission spectrum only in a wavelength range of 400 to 490 nm.

An optical microscope, which includes a first light source, for observing a sample by illuminating light from the first light source on the sample, the optical microscope comprising:
- a second light source that is different from the first light source and is insertable/removable in/from an optical path of the optical microscope, wherein:
- the second light source has a peak of an emission spectrum only in a wavelength range of 400 nm to 490 nm,
- the second light source is included in a storage box of the optical microscope, and
- the second light source is placed in the optical path by storing the microscope.
An optical microscope which includes a first light source, for observing a sample by illuminating light from the first light source on the sample, the optical microscope comprising:
- a second light source that is different from the first light source and is insertable/removable in/from an optical path of the optical microscope, wherein:
- the second light source has a peak of an emission spectrum only in a wavelength range of 400 nm to 490 nm,
- the second light source is placed in a neighborhood of a back focal position of an eyepiece lens,
- the second light source is included in an eyepiece lens cap, and
- the second light source is placeable in the neighborhood of the back focal position by attaching the eyepiece lens cap to the eyepiece lens.
A storage box for storing an optical microscope, which includes a first light source, for observing a sample by illuminating light from the first light source on the sample, the storage box comprising:
- a second light source that has a peak of an emission spectrum only in a wavelength range of 400 nm to 490 nm,
- wherein the second light source is placed in an optical path of the optical microscope when the optical microscope is stored.
An eyepiece lens cap which is attachable to an optical microscope, and which includes a first light source, for observing a sample by illuminating light from the first light source on the sample, the eyepiece lens cap comprising:
- a second light source that has a peak of an emission spectrum only in a wavelength range of 400 nm to 490 nm,
- wherein the second light source is placed in a neighborhood of a back focal position when the eyepiece lens cap is attached to the optical microscope.
