It is intended to record the pulse of laser energy, exceeding a specified threshold level.

APPLICATION

Laser ranging and location

FEATURES

On an input there is an integrating photoreceiver with an output on the comparator. Radiation arrives on an optical cable with an optical connector.

SPECIFICATION

The parameter name Value

The adjustment range of the threshold input power, mW………………… 0,25…0,5.

The total deviation of the threshold in the working temperature range, %, max….. 20

Pulse width of output signal, ms ………………………………….………….. 0,05-2

The wavelength of the input laser beam, msm………………………...…… 1,06 - 1,60

The duration of the laser pulse, ns ………………………..… .. …….…. 10-20

The range of input optical pulse power, mW …………………………….…. 0,25-2,5

Step response time of output signal in terms of amplitude, ns, max……….. 10

Load resistance, ohms, min …………….…………………………………. 1500

Power supply , V………………………………………………………… 5±0,25

The amplitude of the signal voltage at the output level………… TTL, CMOS

Weight, g, max……………………………………………………………... 15

Note - TPD 2 works at the input pulse energy of the laser radiation exceeding the established operation threshold, thus on an output there is an impulse of positive polarity TTL, CMOS levels with duration from 50 nanoseconds to 2 microseconds

DESCRIPTION

TPD 2 is implemented on the standard glass-metal base by hybrid-integrated technology.

Overall dimensions (14,4 Х 19,4 Х 10,7) mm.

Response threshold established by consumer with external multi-turn patentsiometrom

2.2 kOhm
