OHP
is the most essential VISUAL AID in modern education system
and in order to facilitate its use in schools and colleges,
we have designed a low cost or economy model of OHP. There
is not much difference in performance compared to high value
projectors.
Fluctuating
input voltage is a problem in most of the developing countries.
To overcome this, we have developed high frequency A/C power
supply which gives constant RMS Vvoltage to the halogen lamp.
This gives constant light output of OHP at all times and lamp
life increases considerably.
We
also supply single and triplet projection lenses, Fresnel
condenser and other components for OHP.
