Given below is a brief description of these special features : 1) The lens is made of the finest quality optical glass giving crystal clear view with the object being seen in its true natural
colours. 2) This 4X area magnification lens has a large rectangular size (170 mm X 105 mm) specially designed for giving perfectly strainfree vision with both eyes. This enables continuous viewing
for long hours without any fatigue whatsoever. 3) The entire spring balancing mechanism of the magnifier is built inside the magnifier's body, thus providing some unique advantages: a) Most
pleasing form and aesthetics. b) This unbroken external surface can be provided with highly durable surface finish, thus ensuring that the unit retains its aesthetic appeal even after several years
of heavy duty usage. c) Also, because of this enclosed construction this model is the ideal choice for use in highly corrosive or humid environment. 4) This model's enclosed construction is
particularly amenable to Electro Static Discharge (ESD) Proofing, which is mandatory in certain sensitive applications such as in electronics and explosives industries. 5) This model offers both
shadowless as well as directional lighting modes. Although in general shadowless illumination is preferred - there are many applications (eg. study of minute surface defects) where directional
illumination is essential for highlighting defects and other features of interest. 6) Since the lens is held in a slim (but tough) edge from the front side, the user does not lose eye-contact with
the object under view when switching between direct and magnified view.
