Advanced alignment protocol
When the system is installed, the service engineer will establish alignment of the laser beam into the scan
head by verifying the overlay between the NIR laser and one of the VIS lasers. Although routine use
usually does not usually require a complete realignment with the scan head, tuning the laser over large
wavelength increments or changing or cleaning the optics in the laser can cause gross changes in beam
pointing. If this occurs, it is best to use the following protocol to re-establish proper alignment with the
scan head. For this protocol, a partially reflective grid slide is needed (Part number 474028-0000-000,
Test Grid Specimen for LSM). Care must be taken to use low amounts of laser power when using this
slide or the grid can be easily burned.
Begin by confirming that the correct wavelength for the laser is set in the laser control panel in the
software. The wavelength can be changed by selecting the modify option. Refer to the Rees analyzer or
the BRF setting to determine the wavelength of the MIRA 900F.
Next, place the partially reflective grid slide on the microscope stage. Bring the grid slide in focus using
the 10x Plan-Neofluar objective and transmitted light. Configure the scan head as follows (Fig. 9-6):
This configuration is designed to use the PMTs to
detect the reflection of the NIR and VIS laser light
off of the grid slide so an image of the grid is
made on the screen. For this protocol, the 543 nm
line has been chosen. The HFT KP 700/488 beam
splitter is used to avoid sending too much 543 nm
laser light to the reflective slide. A KP 700/543
beam splitter can be used, but care must be taken
not to burn the slide. Alignment using this
procedure will ensure that the NIR and VIS lasers
overlay on the combining mirror when they enter
the scan head.
To perform the alignment, set the laser power for
both lasers at 3 % (1 % for a MIRA 900F with a
10W pump laser) and adjust only the gain to
improve the intensity of the signal.
WARNING: Too much laser power
can cause damage to the grid slide!
Be sure attenuation is set before
scanning.
