Maybe you are aware of it anyway, but just in case to help with your trials: For such high NA objectives, as cover slip/cover glass thickness is critical for best performance, I recall that in the lab there were coverslips with narrower tolerances than the standard ones around. I just had a look at ...
Yeah, when it comes to sourcing used tech equipment, the grass for our US American friends on the other side of the pond is so much greener than over here. :) :wink: Thanks for sharing your thoughts, guys. With your refocussing method findings you have blazed a new trail, Hristo! And thanks for the ...
Thanks for the clarification, Hristo! Have you ever used such an "unbranded" 1501-9398 20x Nikon with good results? Or if not, do you expect they could give good results by your refocussing method? I ask since they are cheaper than the branded ones... after all we disadvantaged Europeans have to pay...
For fragile, delicate objects often so called featherweight forceps are used. They are made of very flexible stainless steel, so the force of the grip is just given by the spring force of the flexible steel which avoids damaging or crushing the fragile objects. I haven't seen locking featherweight f...
What are you using for the vertical linear motion surface for Z(on the back side of this) ? Sandwiched between the two angle brackets is a Newport M-426 linear stage. Also, I've got rough mental plans to motorize my goniometer so I can move the subject itself via Wi-Fi and a pi pico w. Yeah, I have...
Was "the weird Nikon" used here one of those Nikons from a gene sequencer, designed to be used with the thicker glass of a flow cell, just labelled with a number like 1501-9398?
"Hmmmm" indeed, .... for a faecal pellet this object seems to have a lot of structures. From where it was found and from its looks, I am with Scarodactyl, that it reminds of a tapeworm proglottis. Half the size of a sesame seed woud be rather small, and despite your photo through the microscope, one...
I very much enjoy your new stereo pair that shows the mouthparts from below. So many details, lovely! I am surprised to hear about the "endangered" status. Are your Tapinoma species not fond of living in kitchens like ours? As to the "endagered" status: With Germany being a rather densely populated ...
More outstanding photographs! The stereos of the mouthparts are a treat and really rock! And you have even managed to capture the "eyelet" in a living specimen! I wonder why the picture of the petiolus in my key doesn't show it, and neither is it mentioned in the text. Now I have to look at a Tapino...
Attached is a picture how I've added Z and Rz to my diffractometer head with spare parts I had on the shelf for some time. The linear stage, here sandwiched vertically between two angle brackets, would also allow for manual stacking, if this specimen holder/stage was used in a vertical setup below t...
I'm sorry if this has been brought up before a bunch, but please direct me to any keywords I should search for for a rundown on how people deal with specimen holding. I saw this goniometer for a really cheap price online and it seemed appealing, but I was also considering the ~$75 xyz stages I see ...
