PROBLEM TO BE SOLVED: To provide a single crystal growing apparatus capable of reducing energy loss of light (heating source) and efficiently melting a sample.SOLUTION: A single crystal growing apparatus includes a pair of reflection mirrors 1 and 2 each provided with a pair of focuses F0 and F1, F0 and F2 and arranged such that the one focus F0 matches, and heating sources 3 and 4 arranged at the other focuses F1 and F2 of the reflection mirrors 1 and 2, and grows a single crystal by irradiating a sample S arranged at one focus F0 of the reflection mirrors 1 and 2 with radiation heat of the heating sources 3 and 4 directly or through reflection by the reflection mirrors 1 and 2. The respective reflection mirrors 1 and 2 comprise a first ellipsoidal mirror 21, a second ellipsoidal mirror 22 disposed on the outer diameter side of the first ellipsoidal mirror 21, and a spherical mirror 23 disposed between the first ellipsoidal mirror 21 and the second ellipsoidal mirror 22. |
