===== Microscope overview ===== | ===== Microscope overview ===== | ||
- | GABY WORKING ON IT!!!! | + | SIM microscopy is one of the imaging techniques that can overcome the limits of resolution of widefield fluorescence microscopes (~200nm), ie, it allows "sub-diffraction" imaging. By using patterned ("structured") illumination, higher order spatial information is obtained that can then be extracted by computational algorithms in Fourier space. A typical DM OMX-SIM image is a reconstruction of 15 images, where the illumination pattern changes in angle (3x) and phase (5x). SIM works best with shallow samples, such as cells attached to glass, and is less reccomended for tissue imaging. Optimal optical conditions are important to avoid reconstructions artifacts. When successful, SIM can provide valuable information about organelles, cytoskeleton and other fine intracellular details. The speed of acquisition of the DV OMX system also allows live-cell imaging. |

- | SIM microscopy is one of the imaging techniques that can overcome the limits of resolution in a normal widefield microscope (~200nm), by using patterned ("structured") illumination with sliding and rotating stripes. These patterns produce high order spatial information that can later be extracted by computational algorithms in Fourier space. A typical SIM image is a reconstruction of several patterned images, where the illumination pattern changes in both angle or phase in order to extract almost twice the original resolution. in the DV OMX system, a total of 15images are acquired for each image (5x phases x3 angles). SIM works best with shallow samples, such as attached cells, and is less employed for tissue imaging. Optimal optical conditions are important to avoid reconstructions artifacts. When successful, SIM can provide valuable information about organelles, cytoskeleton and fine intra cellular details. The speed of acquisition of the DV OMX system also allows live-cell imaging. | + | |

+ | For more detailed information consult the full SOP/Guide here: | ||
+ | (under construction) | ||
+ | |||
+ | ==== Turning ON ==== | ||
+ | |||
+ | * Turn on the main power switch at the top module | ||
+ | * Turn on the laser chassis module (key switch) | ||
+ | * If necessary turn on temp controller | ||
+ | * Log on the OMX SR sworkstation (user: "worx" Password: "system serial number" | ||
+ | * Start the AcquireSR software, and in the acquistion software click "Instruments|Status" | ||
+ | * In the Instrument status dialog box, select "Restart Hardware" and wait. | ||
+ | * Once hardware restart is finished, select "Reset All Cameras", and wait until the camera SNs are reported in the log box. | ||
+ | * Mount sample and start imaging. | ||
+ | |||
+ | ==== Turning OFF ==== | ||
+ | |||
+ | If you are NOT the last user for the day: | ||
+ | * Transfer your data to the institutional server. Data will be deleted every month! | ||
+ | * Close SoftWorx | ||
+ | * Clean the objective and remove all your materials | ||
+ | |||
+ | Else: | ||
+ | * Turn "OFF" the laser control and Hardware control. | ||
+ | * Log off from the workstation | ||
