XJL-302/302BD正置金相顯微鏡適用于對不透明物體的顯微觀察。采用優(yōu)良的無限遠光學系統(tǒng)與模塊化功能設計理念，可以方便升級系統(tǒng)，實現(xiàn)偏光觀察、暗場觀察等功能，緊湊穩(wěn)定的高剛性主體，充分體現(xiàn)了顯微操作的防振要求。符合人機工程學要求的理想設計，使操作更方便舒適，空間更廣闊。適用于金相組織及表面形態(tài)的顯微觀察，是金屬學、礦物學、精密工程學研究的理想儀器。
XJL-302/302BD upright metallurgical microscope is suitable to observe surfaces of opaque object. It is equipped excellent UIS optical system and modularization function design so that update system expediently ａnd achieved polarization, dark field observation. Compact and steady main frame body is embodiment for the shock resistance. The ideal ergonomic design is adopted in this unit and has easier operation and wider space. This is ideal optical instrument for micro observation in metallographic structure and surface morphology. It is suitable for research in metallography, mineralogy, precision engineering, etc.
