LASER SWITCH

Switch. On the tube of the switch, indicated by the

label, is a small green DOT (LED). With the laser beam

aimed down the axis of the tube, align the Laser Switch

such that the DOT lights up as brightly as possible. The

Laser Switch is now properly aligned with the laser.

Caution: Never attempt to align the laser switch

by sighting with your eye. Never look directly into

the laser. Never use a laser with an output exceed-

ing 0.5 mW unless you are wearing laser safety

glasses and the instructor is present.

The PASCO Model ME-9259A Laser Switch is a high

performance photo switch which utilizes a laser (such as

PASCO Models OS-9171 and SE-9367) as a light source. It

is extremely valuable in the following situations.

➀ When the interruption of the photogate is of very short

duration. Since the rise and fall times of the ME-9259A

are on the order of 200 nanoseconds, this Laser Switch

can easily “see” interruptions on the order of 1 micro-

second.

➁ When the photodetector must be located more than a

few inches from the light source. This is necessary if

the object to pass through the photogate is large, or if

the object’s trajectory is not easily controllable, or if a

combination of mirrors is to be used to allow one laser

and one Laser Switch to start and stop the timer. See

Figure 1.

Set-Up and Alignment

➀ If the distance between the laser and Laser Switch is 5

m or less, a 0.5 mW laser is probably sufficient.

Beyond 5 m, a more powerful laser must be used.

➁ Align the Laser Switch such that the laser beam is

incident upon the input port at the end of the Laser
