Popis:	We developed a cryostat for optical observations at ultralow temperatures and in strong magnetic fields. The optical system consisted of a LED, a light transmission path and a CCD chip, with all components installed inside the inner vacuum can of the cryostat. We have been able to cool a 3He sample to a temperature of 0.6 mK in zero magnetic field and to 2 mK in 9 Tesla, while looking at the crystallization and melting of the solid 3He. The CCD chip gives a heat leak of only 200 pW to the 3He in our Pomeranchuk cell. The performance of the nuclear demagnetization cryostat as well as the optical system are described.
