I haven't put that on Thingiverse yet, mainly because the metal adapter I use to screw it to the lens was from some random lens I had and it's unlikely anyone else can find the same adapter. I would tackle that one by ending the plastic part to a ring, which has outer diameter that matches the inne...

Great test and write-up Robert, I had been waiting for this one! I'm pleased to see I can stick with my Laowa and not bother chasing any further improvements on optical quality at 2x for the time-being. I've been using this lens for about two and a bit years now and it has performed wonderfully, I j...

Haha yes exactly what I had in mind. It did make me think whether these guys happened to come across something like this beforehand. Perhaps something similar evolved independently in the electronics community as well.

Very cool. What's on the bottom of the base? I am wondering how this would secure to a linear stage. Thanks for sharing. The bottom of the base has some small feet to raise it a few mm off the surface and while it has some mounting holes etc, I think it'd be easier to do away with the base and just...

Thanks! It's an open-source javascript plugin called OpenSeaDragon that is used by various museums (e.g. British Museum), auction houses, etc. The implementation depends a bit on how your website is setup and your skill level. If you're a developer, you could probably implement it yourself. Me, I k...

kaleun96, there is a simple cure for the problems you mentiones in axial lighting. Use a half-silvered first-surface mirror, and exchange the position of the camera and light source, so that you are photographing the reflection of the object. Thus you are not shooting through any glass that could d...

Interesting results! I've tried axial lighting many, many times but was never satisified with the results. Yours, however, are much more encouraging. I've used everything from picture frame glass to optical grade beamsplitter glass, to teleprompter glass, and all suffered from "ghosting" (doubling ...

I recently purchased a newly developed "helping hands" tool made by some guys in Sweden primarily for electronics/soldering and thought it might work well as a specimen holder too: https://omnifixo.com/ You can buy two versions: one with a larger base and four magnetic clips, the other has a smaller...

Why go with Thorlabs at all? Just get an 8020 post and a long bolt and bolt it directly to the surface. You can get sufficient force between the two that it won't move. Depending on the spacing between holes, you may be able to use a double or quad and hold it down with 2 or 4 bolts. I am looking f...

I've been looking for a good source to print these. 3D Hub is now "Hub"and wanted $90 to print just one of the smaller ones - they require a $50 surcharge for some reason. Found another site and they ask what Process to use - DLS, DMLS, etc, and what material EPU, SIL, etc. What would you recommend...

These look great. Would you be interested in selling some? Thanks! If you have a 3D printer, you're more than welcome to print them for free, you can find the files here: https://www.thingiverse.com/thing:4916557 If you don't have a 3D printer, I would recommend using something like 3D Hubs, which ...

Hi Cam. Your rail concept is great. I use an aluminum extrusion rig (15 series profile) and your rail should be able to be adapted to my set-up. Can you please describe more the hardware for the rail? Also, what is travel per turn of the knob? Thanks. Josh Hey Josh! Is 15 series similar to v-slot a...

Made some upgrades: Improved the dovetail fit Changed the rollers from the split-wheel design to a solid wheel for greater contact Incorporated the block for the screw nut into the carriage Changed from using an M8 threaded rod to an 8mm "acme" (ISO trapezoidal screw) rod Added a second pillow block...
