Description

The Thorlabs Model LIA100 Lock-In Amplifier is designed to deliver high performance in a compact, cost-effective package. By eliminating some of the less-used features of conventional lock-in amplifiers, the LIA100 offers the performance of units many times its price.

The LIA100 consists of a programmable AC input amplifier, a monolithic phase-sensitive detector (PSD), and a two-stage programmable output low-pass filter. The input amplifier is a two-stage design with an adjustable gain to boost the modulated input. The PSD performs a frequency translation to shift the modulated signal back to its original base band DC. The output filter is a two-stage low pass filter to remove any residual harmonics from the output of the PSD. The output filter has adjustable settings of 10ms, 100ms, 1s, and 3s. In addition, a user-defined time constant can be set by simply adding two capacitors to the LIA100 printed circuit board.

The LIA100 includes a six-position sensitivity control to provide over 60dB of gain adjustment to accommodate a wide range of input signal levels. A monitor output allows the user to monitor the buffered AC amplifier output. A five-position Output Time Constant switch allows the output filter to be set from 10ms to 3s to match the noise and bandwidth of the LIA100 to your signal dynamics (on-board provisions allow a user-specified capacitor to be used for customizing the output filter). A 10X output expand allows the output to be amplified by a factor of 10 (20dB) for optimizing the output signal level for specific data acquisition systems.

Note: The principal advantage of lock-in amplifiers is that all non-synchronous noise (i.e. noise components which are out of phase with the modulated signal) is suppressed by the PSD. This results in a signal-to-noise improvement of many orders of magnitude.

InstraView™ Equipment Inspection



Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
