What Is the Light Demonstration Guide Used For?
It gives students a visible model of how an optical fibre carries a signal, which helps them understand the principles of optical communications. A narrow beam from a ray box or torch shone into one end comes out at the other, showing that light can be guided along a bent path.
What to Specify When Ordering
- Number of bars.
- Any ray box or other light source, which is a separate item for the same enquiry.
Frequently Asked Questions
Why is the bar S-shaped?
The bends make the light meet the inner surface of the acrylic at large angles of incidence, beyond the critical angle, so it is reflected back inside again and again. Seeing the light leave the far end of a curved bar shows that it was guided along the bar by reflection rather than travelling in a straight line.
Why is the bottom of the bar white?
The white underside makes the light inside the bar easier to see.
What should an export quotation request include?
The quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), and any packing, labelling or tender details.
Who manufactures the Light Demonstration Guide?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it in Ambala, Haryana, and quotes for it as the manufacturer.
