Product Description

Digital Laser Power Probe Meter
The Digital Laser Power Probe Meter is a completely portable, easy-to-use calorimeter type power meter. The instrument consists of two components: a microprocessor based digital meter and Probe Head. Different Probe Heads are available to cover various laser types with power ranges from a few watts to over 11 kilowatts. The meter accepts any of the Probe Heads so it is easy to change power ranges as well as check a reading using a second Probe Head of the same type. The digital meter can be used with an optional thermocouple to become an accurate digital thermometer. Like our highly successful dial type "Laser Power Probes," the Digital Laser Power Probe uses timed exposures and is based on the idea that laser power measurement should be quick and easy. Setup should not require special fixturing or time consuming alignment. Ideally, it should be possible to take power measurement at any point in the optical system where losses are likely to occur. Unfortunately, most laser power meters have sacrificed ease of use to gain continuous power readings. In most laboratory and production situations, however, the usual requirement is for quick power spot-checks with minimum disruptions. The Digital Power Probe has several special features. They are:

Increased accuracy is achieved by microprocessor control and a digital readout. The meter automatically compensates for non-linearities and other sources for error in power measurements. Laser power readings are retained until the meter is "reset". This makes taking remote power measurements easy. Extension cables are available for situations when the distance between the meter and the head must be greater than 1.5 meters (5 feet). Power Probe Heads are inexpensive and easily switched. This permits alternating between two Probe Heads so that readings can be made using one head while the other head cools. The Probe Heads can be quickly cooled by water immersion. The Digital Laser Power Probe measures laser power with full accuracy from 20 watts to over 11 kilowatts using four Probe Heads with overlapping ranges. Each probe has better than a 10 to 1 power range. For example, the 220 watt head can accurately measure laser power from 220 watts down to 20 watts. The range, resolution and accuracy for each Probe Head are given in Table 1. The meter can also be used as a digital thermometer by substituting a thermocouple accessory for the Laser Power Probe Head. Temperature may be displayed in either C or F. This feature is very useful for checking the temperature of a cooling system or monitoring the temperature rise of an optical component. New absorption coatings have been developed which are more resistant to damage. See "Probe Head Selection" for more information.
