Lascells Timer Light Gate Mk 2

Lascells Timer Light Gate Mk 2

The Lascells Timer Light Gate Mk 2 has been designed to allow precision measurement of time and velocity.

Applications include: the study of g by free fall, projectile motion and dynamics, and this light gate enables accurate and repeatable results.

Key Features:

• Connection via the 3.5 mm stereo jack to a compatible millisecond timer
• The light gate has an infrared emitter to provide the light beam, and a fast acting infrared receiver (photodetector) for improved accuracy of the measurements. 
• During use, the light beam is continuous until broken by an object or interrupt card moving through the beam, triggering the timer to start or stop.
• Requires a compatible millisecond timer, e.g. TMH-825-100 or TMH-835-100
• Can be used with the light gate adaptor, TMH-815-120, which converts the jack plug to 4 mm sockets for use with timers with 4 mm connectors.
• Two light gates can be combined for more versatility e.g. measurement of acceleration, or when the distance between measurements is large
• Achieves accurate and consistent time measurements with nanosecond resolution
• Includes an aluminium mounting bar, for use with retort stands
