By design and quality optics, these microscopes are recommended especially for long duration work. Ideally suited for biology, botany, archaeology, geology, teaching and electronics.
Three dimensional optical resolution, wide field of view without side aberrations, excellent crisp contrast and true colour.
Rechargeable battery 3x1800Ah and external charger.
Binocular head inclined at 45° with adjustable interpupillary distance from 55 to 75 mm.
Rotating head of 360° with easy access for large items. Dioptric correction in the left eyepiece of ±5dp.
Ocular head held with secure fixing screws.
Pair of eyepieces, wide field of view WF 10x (23 mm Ø). In the model ZTX-3C. Pair of eyepieces, wide field of view WF 20x (20 mm Ø). In the model ZTX-20. Objectives of 2 x and 4 x, located in a double objectives support turret with rotation in both directions.
Double focus: by means of a vertical slip clutch of the head up and down a column, with fine adjustment using a bilateral macrometer with rack and pinion tension and control.
Solid base consisting of a platform with double contrast (black and white) circular plate and translucent etched light diffuser, with fixing screw and holding clips.
System with triple illumination of low voltage, with incident light (episcopic) in the head and transmitted (diascopic) in the circular platform, Activated individually or simultaneously, with controllable intensity. Also the incident light incorporates a condenser lens with an extractable blue filter.
