Our LSKGG4(/M) Galvo-Galvo Scanner utilizes two galvo scan mirrors that deflect an incident laser beam in X and Y. Identical to the galvo-galvo scanner used in our Bergamo® III multiphoton microscopes and complete Cerna®-based confocal systems, each mirror has a mechanical scan range of ±7.5°, corresponding to an optical scan range of ±15°. This range is large enough to explore the entire diffraction-limited FN20 field of view of Thorlabs' SL50 scan lenses for laser scanning microscopy.

The scan head is connected to the controller using the included DB25 cable. If using the BNC input connectors to drive the galvo mirrors, a drive voltage of ±10 V at an impedance of 10 kΩ will be required for each axis. The BNC output connectors have a voltage range of ±3.75 V and an impedance of 1 kΩ.

The scan head has a mass of 0.56 kg, so it may be useful to support it directly using a Ø1/2" post or Ø1" post. Four 1/4"-20 tapped holes (M6) are located on the bottom.

SCANLAB

Each scan mirror has a protected silver coating that provides high reflectance in the visible and NIR; see the Specs tab for details. Since the coating is metallic, its performance varies minimally over the ±7.5° mechanical scan range of the mirror.

A National Instruments (NI) 68-pin connector is available to directly control and monitor the scanner via an NI card or breakout box (not included). The beam can also be steered by supplying DC, sine, sawtooth, or triangle wave drive signals through two BNC connectors. Two additional BNC connectors provide X and Y position feedback signals. This scanner is also compatible with Vidrio's ScanImage software.

Galvo Scanner

MountingThe input face of the scan head has internal SM05 (0.535"-40) threads, internal SM1 (1.035"-40) threads, and four Ø6 mm bores spaced for our 30 mm cage system. The output face has internal SM1 threads and four 4-40 taps for our 30 mm cage system.

Note because the galvo-galvo scanner can be steered using multiple methods of input signals, neither BNC cables nor an NI 68-pin cable are included.

Please note that the scan lens needs to be positioned such that its entrance pupil is at the midpoint between the galvo mirrors; when being used at the input, the distance is 27.255 mm, while at the output, the distance is 29.045 mm. For the CLS-SL Scan Lens, an LCP02(/M) Cage System Size Adapter can be used to convert the 30 mm cage system to a 60 mm cage system to mount and position this scan lens at the correct distance using a LCP8S Cage Plate. An SM1A70 adapter with external SM1 and internal SM30 mounting threads will position our SL50-CLS2, SL50-2P2, or SL50-3P Scan Lens at the correct distance from the scanner output port.
