Bresser, Microscopio invertito professionale da laboratorio Nexcope NIB620 a contrasto di fase

Inverted microscopes are primarily used for inspecting cultures. The NEXCOPE NIB620 is the ideal professional microscope for this purpose. The specimen is illuminated from above and inspected from underneath. This inverted design enables microscopy of plankton, microalgae and cell cultures . This allows cell cultures to be examined directly in the culture vessel without taking samples. This special microscope can be used in a wide range of applications, such as water management agencies, research institutes and universities, human and veterinary medicine, agriculture, marine biology, limnology and aquaculture . The inverted design prevents the lenses from coming into contact with the fluid. The specimen does not need to be covered, and the coating thickness is irrelevant. Culture vessels require a base thickness of 1.2 mm. The integrated display informs you at any time about the selected magnification and the status of the illumination as well as the sleep mode. The brightness can be programmed for each objective so that there is no need to readjust when changing magnification and the user is not blinded. OBJECTIVES The NEXCOPE NIB620 microscope is equipped with a quintuple nosepiece. One planachromatic 4x objective, and one each of 10x, 20x and 40x planachromatic phase contrast objectives are included. The condenser has a numerical aperture (N.A.) of 0.3 and an extra-long working distance. EYEPIECES The eyepieces have a 22 mm field of view . Thus you achieve a very large field of view. The high eyepiece head is ideal for spectacle wearers. A rubber edge protects against scratches on contact. A diopter compensation of -5 to +5 can be set individually for each eyepiece. The interpupillary distance can be adjusted between 48 mm and 75 mm. You can adjust the angle of the binocular part according to your posture and physique. ILLUMINATION The powerful 3 W LED has an adjustable brightness and provides the best possible illumination. The brightness can be adjusted individually for each objective. When an objective is changed, the NEXCOPE NIB620 automatically adjusts the previous brightness settings. The display shows the currently selected objective and the current brightness. The adjustment-free condenser enables quick readiness for use. The condenser can be removed for bright field observations in order to create more free space. MECHANICS In addition to the coarse focus , the fine focus helps to render a very sharp image of the object. A full turn of the fine focus moves the stage up/down by 0.2 mm. On the right side, fine focusi can be done with one finger. The friction of the coarse focus can also be adjusted. The fine focus knobs are held in place magnetically and can be replaced as needed. The cross stage offers the possibility to insert different holders. For example, you can insert slides or petri dishes. The microscope can also be operated without the cross stage. This creates a large, flat surface. CAMERA CONNECTION The NEXCOPE NIB620 is specially designed for use with c -mount cameras . You can choose from two different adapters, depending on the sensor size: 0.5x C-mount adapter for sensor sizes up to 2/3’’ 1x C-mount adapter for sensor sizes of 1’’ A corresponding 1x c-mount camera adapter is included in the scope of delivery. The camera connection is on the side and has a rod between visual observation and camera (100/0 or 0/100).
