Product : B-380 Series Upright laboratory microscopes. Optical system & objectives: The models of the B-380 series are equipped, depending on the version, with two different types of optical systems: the standard 160mm one and the infinity-corrected system (IOS). In both cases, the field diameter of the eyepieces is 20mm. The focuslenghth of the tube lens is 180 mm the parfocal length of the objectives is 45 mm. Microscope stand: Modern and ergonomic, this stand is made of die-cast aluminium. Coarse and fine focusing (graduation: 0.002mm) with coaxial control knobs. Adjustable focusing tension and limit stop. Heads: Available in binocular or trinocular version. The heads are equipped with interpupillary distance control (55-75 mm) as well with dioptric compensation. All heads are 360° rotatable and 30° inclined. Illumination: The illuminating system consists of X-LED source. The brightness can be adjusted by a rheostat located on the left side of the microscope base. X-LED 3 – The future of illumination OPTIKA is proud to introduce its own revolutionary LED powered illumination system. Developed by our R&D dept. it consists of a new combination of LED and optical technology. A new high-efficiency single chip LED works in combination with a special optical lens, which allows to double the intensity of the light generated by the LED itself. The result is a quantity of light equivalent to the light generated by a standard 50W halogen bulb, but with a colour temperature of 6300K. It means white light instead of the yellow one produced by halogen bulbs. The electrical consumption (3.6W only) shows the high efficiency of the system: the same light intensity with less than 10% of the consumption of a standard halogen bulb. Last but not least, the lifetime of our LED is 50.000 hours, instead of 1.500 hours.
