B-380 Series
Upright laboratory microscopes.
Your routine work requires long hours on your microscope. Easily accessible controls, including the stage drive, fine focus and brightness control combined with Optika’s revulotionary ALC system grants maximum comfort and relaxed working conditions.
Optical system & objectives:
The models of the B-380 series are equipped, depending on 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 fokuslenghth of the tube lens is 180 mm the parfocal lenght of the ojectives 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: 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 ...!
B-383PL
The B-383PL is a microscope designed specifically for advanced teaching and routine laboratory work. The cast iron tripod provides high stability and ergonomics.
lighting
The light intensity of theX-LED3 can be adjusted using a rotary knob on the left-hand side.
Focus
Coaxial coarse and fine focus with preset stop to prevent the lenses from coming into contact with the specimen. The turning resistance of the coarse drive is adjustable.
Cross table
The mechanical object stage measures 150 mm x 139 mm, has a two-layer design and is equipped with a scratch-resistant surface. The vernier scale has an accuracy of 0.1 mm.
Microscope head
The trinocular microscope head can be rotated 360°. The view is tilted by 30°. Diopter adjustment is possible on the left eyepiece. The eyepiece distance can be adjusted between 48-75 mm.
Revolver
Five lenses can be screwed into the ball-bearing revolver.
Condenser
The fold-out Abbe-type condenser has a numerical aperture of 1.25 and can be centred.
