Lens Big Manufacturer,Supplier and Exporter in India

Lens Big (Product Code: SLE/LSM/04) is a large hand lens used to enlarge leaves, seeds, insects, fabric and print during primary science and nature-study lessons. Its 75 mm diameter gives a wide field of view at 2.25X magnification, so two or three children can look through one lens together. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for schools that want a simple hand lens magnifier for school science.

Specifications

What Is the Big Lens Used For?

A big, low-power lens is the easiest magnifier for young learners. At 2.25X the whole object stays in view, so a child can follow an ant across a leaf or compare the veins of two leaves without losing the subject. Typical activities include looking at soil and sand grains, comparing fingerprints, examining flower parts and reading very small print.

Show pupils to hold the lens still and move the object, or keep the object still and move the lens, until the image is sharp. Never look at the Sun through a lens, and do not leave it lying in direct sunlight, because a lens can focus the Sun’s rays and scorch paper or skin. Wipe it with a soft cloth to avoid scratches that blur the view.

Frequently Asked Questions

What magnification and size is the Lens Big?
The Lens Big (SLE/LSM/04) magnifies 2.25X and has a lens diameter of 75 mm. The low power keeps the whole object in view, and the large lens lets young children find the subject quickly, which suits early-years and primary observation work.

How is the Lens Big different from the Linen Tester?
The Lens Big gives a wide 75 mm view at 2.25X for whole leaves, insects and objects, while the Linen Tester is a fold-up magnifier at 10x for close texture such as cloth fibres or paper. Many schools use the Lens Big first and the Linen Tester later.

What is the Lens Big made of?
The Lens Big listing states its 2.25X magnification and 75 mm diameter but not the lens or handle material. If material matters for your age group or tender, ask us through the contact page and we will confirm it before you order.

How should the Lens Big be cleaned and stored?
Clean the Lens Big with a soft, dry lens cloth and store it in a box or drawer out of direct sunlight. Sunlight passing through any lens can be focused into a hot spot, and a scratched surface makes the magnified image less clear.

Who supplies the Lens Big?
The Lens Big is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala in Haryana, India. The company supplies Science Material items to schools, dealers and importers in India and international markets.

Can schools buy the Lens Big for a whole class?
Yes, the Lens Big can be quoted in class and bulk quantities as well as single pieces. State how many lenses you need and your delivery location when you enquire, and ScienceLab will send a quotation for delivery within India or abroad.
