Digital Power Probes

DIGITAL POWER PROBE PRODUCT INFORMATION

PROBE HEAD SELECTION

Eight different Probe Heads are available for use with the DM5 Digital Meter. The Probe Heads have four different power ranges (designated D1, D2, D3, D4). The Probe Heads are also available with two absorbing coatings designated Y and C.

The Y series Probe Heads have a broad spectral absorption coating that is particularly useful for YAG lasers but covers a spectral range from 0.4 to 6 microns. This coating can also be used with CO2 lasers.

If the Probe Head is to be used with only a CO2 laser, then the C coating is preferred. The C coating does not exhibit damage until the aluminum substrate is close to melting. The D3C and D4C Probe Heads are conical in shape allowing for a higher damage threshold.
