Ideal for secondary schools and colleges, the Lascells Fibre Optics Kit enables hands-on exploration of fibre optic principles and data transmission, making complex physics concepts accessible for students. This robust, self-contained kit is designed for classroom demonstrations and practical investigations into light, communication, and wave behaviour.

• Includes transmitter (LED, 660nm deep red) and receiver (photodiode) units

• Offers variable frequency modulation (1–400Hz) and a 250kHz square wave for speed of light experiments

• Supplied with 5m and 20m sheathed polymer optical fibre coils, each with clip housings

• Receiver features a variable gain amplifier with integral loudspeaker and oscilloscope monitoring sockets

• Powered by 9V PP3 battery per unit (B8R05410, not included)

• Full instructions provided; suitable for demonstrating total internal reflection, data transmission, and speed of light (oscilloscope required for some activities, not included)
