Boston Electronics is currently demonstrating its new Chop-In Opus 1 digital dual-phase lock-in amplifier and phase-locked optical chopper combination at Photonics West booth 814.

The Chop-In Opus 1 is computer controlled, and only needs USB power to operate. This greatly simplifies laboratory set ups as there is no need for multiple control boxes and power supplies.

Using the inherent processing capability of a computer, the Chop-In software enables lock-in performance at frequencies up to 5kHz, controls all hardware, implements signal acquisition, digital demodulation and filtering.
