I was pulling apart an old LaserTec C140 confocal microscope. Here are some pics! Here’s the main optical block:<\/p>\n\n\n\n

There’s a photodiode, I assume with a pinhole and CCD sensor here:<\/p>\n\n\n

On the other side of the unit there’s an FPGA.<\/p>\n\n\n

Under the unit there’s a stepper (right) and a BL55 “Laserscale”.<\/p>\n\n\n\n

I’ve been trying to figure out how all this fits together. The unit appears to be white light only, but I’m unclear on where the actuation is. It looks like everything is on the bottom of the unit. I guess the BL55 laser scale is used in combination with that stepper. But I’m not clear if there’s a full sub-micron precision XYZ stage here or if there’s something else going on. I was really expecting to see Galvos to scan the spot across the sample… hmmm.<\/p>\n","protected":false},"excerpt":{"rendered":"
