Optical Apparatus and an Observation Apparatus Having the Same For Observing Micro Particles

摘要

Disclosed is an optical device for illuminating a chip having a sample provided thereto with a beam in an apparatus for observing the sample. The optical device comprises a light source; and a first reflector reflecting the beam of the light source to allow the reflected beam to be incident on the chip at an inclined angle. In addition, the invention provides an apparatus for observing micro particles having the optical device. When the light of the light source is incident on the sample at an incline angle according to the optical device of the invention, it is possible to maximize a transmittancy of the light. Accordingly, the light emitted from the sample is clearer and a clear image can be thus obtained.
