| | About Comparison Microscope By optical zoom, comparison microscope is used for macro of micro comparison of two or more objects in cutting or overlapping view field through one group of eyepieces observing left and right objective view fields. As clear imaging, high resolution, so you can identify the small differences Brief Introduction of Comparison Microscope NCC-500B 1. Advantages: NCC-500B Comparison microscope successfully solved the technical problems of comparing ridge width and consistency adjustable (this technology is included in the national technology security projects), NCC-500B is an upgraded product improved on NCC-500A model, which not only retains excellent technical performances of NCC-500A, but also increases its image quality and magnification, increases illumination ways and a variety of accessories, shape, structure more beautiful, reasonable, reliable, and makes the instrument fully plays its functions of comparison and identification. 2. Applications: This product is an ideal instrument for public security, inspection, court on document retrieval, marks checking and school teaching (used for bullets, tool marks, fingerprints, seals, texts, coins comparison and identification), but also for industries and sectors such as banks, archaeology, electronics, biology, agriculture which need to identify on objects to use. | | Optical Magnification Range | 3.1×-120× | | Eyepiece | 10×,16×, 25× | | Objective | 0.64×, 1×, 1.6×, 2.5×, 4×, 0.4×(Optional) | | Bridge Magnification | 1.2× | | Photograph Magnification | 3× | | Video Magnification | 0.44× | | Working Distance | 100mm | | Stage | 70mm×70mm, moving range: 51mm×51mm, vertical 54mm | | Horizontally Moving Range | 45mm | | Coarse Elevating Range | 49mm | | Illumination | 12V/50W Halogen, adjustable, air-blast strong light source | | Cold Light Source | 12V/50W, adjustable, Φ10mm | | Power Supply | 220V AC input, 12V DC stable Voltage Output, fit for International safety standard | | Color Video Recording System | Matched with CCD color video recording head and professional monitor and video frequency print, to realize multi people observing images, discuss, study and images real-time output. | | Images processing system | Matched with computer and images processing software, to realize intelligent dealing analyzing of images, and saving of analysis result, share or outputting of remote Internet. | | Images photographing system | Optic or digital camera and video recording camera of various types. | | 0.4× wide view field low magnification objectives | Use with 10× standard eyepiece, objectives vision field nears Φ60mm. | | Bullet holder | Used for observation of warhead and shell case. | | Trans-illumination | Use for observation of transparent and semi transparent specimens | | Polarization | Wipe away stray light | | Coaxial light | Used for some objectives with deep hole trace, small trace or with smooth surface |
