1 FIBRE OPTIC CABLE, UNSHEATHED Bare (unsheathed) fibre optic cable, available in one metre lengths only (not in longer continuous lengths). Unsheathed cable illustrates the magical qualities of optical fibre light transmission. Cat No. Description Price Per OPL-250-100 Fibre Optic Cable, Unsheathed 2.07 1m 2 LASCELLS FIBRE OPTIC PROBE A white LED source with detachable fibre optic cable. The LED can be powered by any low voltage supply and when the fibre optic is inserted the beam can be seen coming from the fibre. Used for demonstrating the principle of light transmission along fibre optic 3 S-SHAPE BLOCK An acrylic block in the shape of an open ‘S’, for demonstrating total internal reflection (TIR). When a laser or parallel light beam is shone into one end of the block, the light rays can be seen reflecting off the internal walls as the light passes along the block, demonstrating TIR. A very crude form of optical fibre. Dimensions approx. 220 x 20 x 20mm. Cat No. Description Price Per OPR-350-100 S-Shape Block 9.43 ea. 4 LASCELLS FIBRE OPTICS This set provides a rugged, self-contained system for demonstrating and using a fibre optic communications link. The transmitter offers a choice of modulation – a variable frequency audio tone and a 250 kHz square wave for speed of light investigations. The receiver contains a user variable gain amplifier with integral loudspeaker as well as direct monitoring sockets for an oscilloscope. The system comes complete with 5m and 20m sheathed polymer optical fibre coils terminated with clip housings to mate with the transmitter and receiver units. The wavelength used is in the visible red part of the spectrum and with the modulation set at 1 Hz the pulsing beam can be easily seen, so that the fibre optic principle can easily be demonstrated. Full experimental details included. Also available separately are 5 metre and 20 metre lengths of unterminated fibre optic polymer cable. Cat No. Description Price Per OPL-265-100 Fibre Optics 292.48 ea. OPL-265-110 Fibre Optics Polymer Cable, 5 Metres 37.22 ea. OPL-265-120 Fibre Optics Polymer Cable, 20 Metres 91.43 ea. cables. Cat No. Description Price Per OPL-255-150 Fibre Optic Probe 43.33 ea.
