Precision Duo Scale "Tech-Line Series"

The duo-scales are, as its name states, two scales in one. You can find the common visible macro scale (Ø25 mm) as well as a micro scale (Ø2.5 mm) in the bottom half of the disk. Based in a black plastic ring, the scale floats/hovers over the object which prevents scratches.

The scaling, which is made out of hard-chrome, has purposely been applied on the underside of the hard-glass disks to prevent parallax error.

Five Scales to Choose from (Scale Number correlates to the position of the pictures):
More details on each scale are to follow and until then can be provided on request.

• High quality, aplanatic silicate glass optics. In the low magnification range, biconvex optics / bifocals are used.
• The silicate-glass optics used in Schweizers Tech-Line magnifiers are 100% manufactured in Germany. Not only do they contain the best optical features, they are also very scratch-resistant! (especially in comparison with plastic lenses).
  - All magnifiers with a silver coating are coated with a special 2-component-coating:
    Resistant to hand perspiration.
    Resistant to nearly all solvents/chemicals.
    Very hard and plane surface, scartch-resistant and easy to clean.
  
  
• Schweizer uses environmentally-friendly, energy-saving and extremely long-life high-performance LEDs (light colour approx. 6000 K).
