مايكروسكوب متخصص في حالة ممتازة شريته من امازون الامريكي للبيع لاعلى سعر المواصفات: Amscope 40X-1000X Plan Infinity Compound Microscope with LED Koehler Illumination Model No: T670Q-PL Key Features: Infinity-corrected optical system with Koehler illumination Five Plan objectives: 4X, 10X, 20X, 40X, 100X Highly-expandable microscopy system Trinocular port for adding photo/video capability Detailed Description This is a highly-versatile, research-grade microscope with an infinity-corrected Plan optical system and LED Koehler illumination. The infinity-corrected optical system allows for introduction of inline-components without the limits of a finite tube-length. This includes episcopic illuminators, such as a fluorescence kit. The quintuple nosepiece provides quick access to five objective lenses (4X,10X,20X,40X,100X). The Plan achromatic objectives provide excellent correction for both chromatic abberation and field geometry. With the 10X wide-field eyepieces, the magnification ranges from 40X to 1000X. The Siedentopf head-design allows for compensation-free interpupillary-adjustment. Following Koehler illumination principles, the LED light-source provides bright, even illumination with a field-diaphragm for precision control. This is an ideal instrument for clinical offices, veterinary and research labs, and anyone who wants an expandable microscopy-system.
