The ADM -1000 offers laser users a new level of power-measuring performance combined with the ease of using a hand-held power meter - all at an affordable price.

The specialist design team at Lasermet developed the ADM -1000 in response to customer demand for a laser power meter with better quality and performance - one that is truly responsive, accurate, stable and easy to use.

The result is a convenient hand-held power meter with a response rate that is effectively instantaneous and the ability to make consistent, accurate measurements of peak and average power. For pulsed laser users, the ADM-1000 offers the precision to measure and display waveforms up to 400kHz.

At the heart of the system is the Lasermet Advanced Detector Interface (ADI) which has been specially configured to enable the ADM-1000 to measure significantly smaller and faster signals than conventionally-used meters. The ADI allows the electronics to be placed close to and optimised for each detecting head thereby achieving maximum performance every time.

The hand-held Advanced Digital Meter, which provides clear digital and graphical displays, is used in conjunction with any of the Lasermet detector heads. There are a variety of high-performance photodiode and thermal heads to choose from depending on the laser characteristics and type of measurements to be undertaken.

This versatile instrument has a wide variety of applications including:

• Production calibration	• Instantaneous measurements
• Automatic laser stability testing	• Laboratory or field use
• Direct peak power measurement for pulses of 4 µs or longer	• Medical laser output power / energy check
• Pulse energy measurement	• Measurements in confined areas
• Pulsed laser characterisation	• Laser tuning
• Oscilloscope function

Advanced Digital Meter ADM -1000

• Average and peak power measurement

Detector Heads

Standard photodiode heads.
These are supplied complete with integrating spheres for maximum reduction of reflections, easy alignment and high accuracy. UV- and IR-enhanced options are available

Compact photodiode heads
Designed for limited spaces with no integrating sphere, this head has a depth of only 25mm. These are available in standard and UV-enhanced options

Thermal heads
These have been designed with performance and ease of use in mind. They include:

• patented advanced speed-up circuitry giving a response time of 20 ms
• patented advanced integrated temperature stabilisation circuitry to massively reduce drift & thermal interference
