Scitec Instruments sells various laser and power measuring instruments including those for OEM applications:

	LM 100 - Laser power meter
	LEM 2410 - Pulse energy and power measuring instrument
	LEM 2510 - OEM pulse energy and power measuring instrument for industrial 19" systems
	PM 200 - Laser energy meter with high dynamic range

LM 100

Features

	Large analogue display
	7 ranges (30 mW - 30 W)
	Mains and battery operation
	Integrated charging unit
	Battery life time: 30 hrs
	Time constant: 1 sec
	Solid metal case
	Outer dimensions: 70 x 120 x 65 mm³

This read out unit is designed to measure the output power of different lasers in combination with a thermophile head. The maximum power is limited by the power head used.

Normally, the time constant of a power head is in the region of 15 to 25 seconds. Use of the read out unit enables reduction of the time constant of the whole measurement system to one second.

A special adapter is required for connecting the head (15pin Sub-D to BNC). This adapter is used for matching sensitivity and thermal characteristic.

The LM 100 is equipped with a rechargeable battery and charging unit. The LM 100 can be operated either using the mains supply or the rechargeable built-in batteries. This makes it versatile and adaptable to most applications.

The batteries are automatically charged when the instrument is plugged into the mains AC power supply. The batteries can also be charged when the LM 100 is turned off. The charging circuit prevents the batteries from being overcharged. The state of the batteries and the charging circuit is displayed by two LEDs.

PM 200

Features

	High sensitivity
	Analogue and digital display
	low noise
	Computer interface and software available
	Incl. pyroelectric detector with meter ranges from 3 µJ to 200 mJ

In the past laser energy meters often required a whole selection of pyroelectric detectors for measuring different energies. From this point of view the PM 200 is a very modest instrument.

A single detector enables monitoring of energies from the detection limit at 3 µJ up to highest energies of 200 mJ. The active sensor area with an aperture diameter of 34 mm ensures simple and reliable alignment for the detection of large beam profiles.

For fast and comfortable tuning alignments the pulse energies are displayed by an analogue meter. Simultaneously, a 3.5 digit LCD display gives the precise value of single shot energies for accurate fine adjustments.

The common practice of continuously switching meter ranges has essentially been made obsolete by the digital readout.

A further feature of the PM 200 is the effective suppression of noise by the signal preamplifier that is directly built into the sensor head. The ‘Sync Out’ output supplies TTL pulses for synchronisation.

In addition the detector signal can be observed (e.g. by an oscilloscope) using the BNC socket. This output delivers a DC voltage proportional to the measured pulse energy e.g. for connecting a chart recorder.

Optional intelligent RS 232 interface for remote control and data acquisition via computer.
