Under some circumstances some manufactures will do lens repairs. Several years ago I won a Zeiss Plan Apochromat 100x/1.4 on eBay for a very good price. When I got the lens it was covered in oil to the extent that oil was actually dripping from it, the foam pad in the bottom of the vial was saturate...

Re: unmount polarizer filters
. . . (BTW, the right filter has a kind of horizontal axle: in what kind of application does one need that?) The last filter should fit one of the drop-in filter slots available on many Optiphot vertical illuminators. The pins keep it from falling too far into the slot and the screw provides a conv...

It may be that it's missing only the rod that moves the internal DF tube into or out of the optical path. People remove them all the time to use in other equipment. Ask the seller to insert an M4 x 0.7 threaded rod and see if it will engage the threads on the BF/DF slider. The rod, either a long scr...

Would it be reasonable to file it down from an existing screw? I personally would run an over-long screw through a nut, hold the nut in a vise (so as to not damage the threads), file the end, then cut off to the desired length. A slotted head can be cut with a hacksaw or a dremel. Yes, but I wouldn...

Wonderful pictures Walter. Walter and Pau, If you're not already doing so, and if the time between exposures is long, you can reduce bleaching by placing a shutter between the lamp and subject, opening it just before and closing it just after the camera shutter opens and closes. Probably a silly que...

This method works pretty well for applying adhesive backed flocking inside cylinders. I know it seems like a lot of steps but after the first time it goes very quickly. You'll need protostar, superglue, and a dowel at least a few inches longer than the protostar. 1) Cut your protostar to size plus a...

Another advantage is due to the fact that the tube lens may not be designed for cross polarization and putting the analyzer behind it in some cases can degrade the polarization state of the light. There's no reason to retain polarization after the analyzer. In critical applications a waveplate is a...

IMS Schneider makes drivers that have a "gear shift" mode that allows changes between full steps and micro-steps on the fly without loosing position. No need to engineer anything. Check out IMS IM481H if you're not already locked into a specific driver type. Prior Scientific uses these in their cont...

. . . . Despite not having experience with this equipment, to me the coupling between both tubes doesn't seem right (red arrow) That coupling is exactly as it should be. The amount of space there doesn't matter once the parfocal distance is set correctly except that moving that tube up or down will...
