5313309 Stereomicroscopes with Zoom

APPLICATIONS 
By design and quality optics, these microscopes are recommended especially for longduration work. Ideally suitedforbiology,botany,archaeology,geology, teaching and electronics.

COMMON FEATURES 
Variable magnification using a continuous zoom control, with control knobs on either side to enable parfocal centralised focus. 
Three dimensional optical resolution, wide field of view without side abe- rrations, excellent crisp contrast and true colour. Optics are protected against knocks. 
Binocular or Trinocular head (Model dependent), inclined at 45°. Adjustable interpupillary distance from 54 to 75 mm. Rotating head of 360° with easy access for large items. 
Dioptric correction of ±5 dp in both eyepieces. 
Ocular head fixed with secure screws. Rubber eyecups. 
Pair of eyepieces wide field of view WF20x (12 Ø) or WF10x (22 Ø) mo- del dependent. 
Macrometric focus: by means of a vertical slip clutch with a fine adjustment using rack and pinion tension control. 
Solid base consisting of a platform with double contrast (black and white) circular plates and translucent etched light diffuser, with fixing screw and holding clips. 
Triple illumination LED system, low voltage with incident light (episcopic) in the head and transmitted (diascopic) in the circular platform: activated in- dividually or simultaneously, with controllable intensity.

Model SQF-E LED trinocular 
Same characteristics to theSQF-D LED model, except that the head is trinocular and it is supplied withaphotographyadapterandeyepiece WF10x withanadjustablefocus visor. The photographic eyepiece and camera with support T2 PK and trigger cable have to be ordered as accessories.
