B-350 Series - Advanced Biological Microscopes for Teachers
The brand new series B-350 strikes the right balance between price and quality. Thanks to the variety of its microscopes, it can be successfully used both in advanced teaching situations and in laboratories. Professional users will certainly value the technical characteristics of the B-350 series that make its high quality microscopes resistant and reliable.
Optical system & objectives
The series B-350 microscopes are equipped, depending on the various models, with two different types of optical system: antifungus 160 mm standard and infinity corrected system (IOS). In both cases the field diameter of the system is 20 mm. The series B-350 includes 8 models featuring achromatic, planachromatic and infinity corrected plan objectives.
Microscope stand
Modern and ergonomic, this stand is made from die-cast aluminium. Macro and micrometric focusing (graduated, 0.002mm) with coaxial controls. Adjustable focusing tension and upper limit controls.
Heads
They are available in binocular and in trinocular version suitable for photography/video applications. Both heads are equipped with interpupillary distance control (55- 75 mm) as well as with dioptric compensation. WF10x/20mm eyepieces also suitable for people wearing spectacles. All heads are 360° rotatable and 30° inclined.
Illuminator - The X-LED Illumination System
OPTIKA Microscopes is proud to introduce a revolutionary LED powered illumination system. This system has been developed by our R&D dept. and it consists of a new combination of LED and optical technology. A new high-efficiency single chip LED improved by a special optical system doubles the light intensity generated by an ordinary LED. The resulting light is comparable to the light generated by a 30W halogen lamp but with a colour temperature of 6300K: this means a white light instead of the yellow one produced by filament lamps. The electric consumption (3W only) proves the high efficiency of this system: the same light intensity with less consumption; 10% of an ordinary 30W halogen lamp's consumption.
In addition, the lifetime of the LED is 50.000 hours instead of the 1.500 hours of an ordinary halogen lamp.
Condenser
Included in the package is an Abbe type condenser. It can be centred through a double-control system and adjusted in height through a rack-and-pinion mechanism by means of control knobs located on both sides of the microscope stand. The condenser is also fitted with an iris diaphragm whose aperture can be adjusted with graduated reference scale. The phase contrast models are equipped with a special phase contrast/brightfield/darkfield condenser.
