Teledyne FLIR Defense Expands identiFINDER® R425 Capabilities

Backward-compatible upgrades broaden isotope identification and add alpha/beta probe support for existing detectors.

Teledyne FLIR Defense today announced upgrades to the identiFINDER® R425 handheld radionuclide identification device, expanding its isotope library and adding support for an external alpha/beta probe. Introduced at CBRNe Convergence 2026, both upgrades are backward-compatible with R425 units already in service, allowing agencies to extend their detection capabilities without replacing their detectors.

Agencies operating the R425 or R425 UW variant can access the expanded isotope library through a remote firmware update and add alpha/beta probe capability with an accessory adaptor. The expanded library is available to existing customers free of charge, helping agencies build on their current equipment investment.

Expanded contamination-screening capability

The new adaptor connects the R425 to a commercially available alpha/beta probe, enabling operators to check personnel and surfaces for alpha and beta contamination without carrying a separate survey meter. Gamma and neutron detection remain built into the handheld device.

Broader isotope identification

The firmware update expands the R425 isotope library by over 40 percent and updates its identification algorithms, enabling the detector to recognize a wider range of radiological threats.

“Our identiFINDER customers have spoken, and we have listened.” said Clint Wichert, Vice President of Detection. “We have expanded our isotope library to address additional threat materials and are making the expanded library available to existing customers free of charge. By integrating support for alpha and beta contamination screening with our field-proven gamma identification and neutron detection capabilities, we are giving operators a full spectrum solution that builds on the equipment they already trust.”

“These quality of life updates demonstrate our continued investment and commitment to our customers on the front line of Radiation detection.” Clint added.

This announcement follows Teledyne FLIR Defense’ recent award of a $6M Delivery order to FEMA.
