476301 Light Transmitter and Receiver

Light Transmitter and Receiver For measuring the velocity of light and also the refractive indices of optically transparent liquids as well as optically transparent solids using an electronic modulation method. The light only needs to travel short distances (a distance of just 2.5 m between the transmitter and the receiver provides measured values with an accuracy of ± 1%). Fig.: 476 30 with 300 11 Light transmitter: Transmitter: light-emitting diode (red, 670 nm) with condenser Modulation frequency: 60.0 MHz ± 5 kHz Power supply: via cable from power supply of the receiver Dimensions: approx. 12 cm x 7 cm diam. Rod: 10 mm diam., 115 mm length Weight: 0.8 kg Receiver and power supply unit: Sensor: silicon PIN photodiode Output voltage: reference channel approx. 2 Vpp working channel approx. 2 Vpp Signal-to-noise ratio: 46 dB Load resistor: higher than 2 kΩ Mains supply: 115/230 V, 50/60 Hz Power consumption: 15 VA Fuses: for 230 V: T 0.125 B, for 115 V: T 0.2 B Dimensions: 21 cm x 20 cm x 23 cm Weight: 3.5 kg Scope of Delivery: 1 Light transmitter with condenser 1 Receiver with power supply unit 1 BNC cable, 6 m 2 BNC cables, 2 m   INSTRUCTIONS FOR USE CLICK HERE
