Re: Benthic diatomeas

They are quite common in my benthic samples. Let me know how could I prepare a slide and I may send it to you. Would it be enough if I sent them in an eppendorf tube in 70% ethanol? You could mount them into a permanent slide. Neutral balsam, or even UV resin will work well enough. You can manipula...

Re: What features and comforts would your hypothetical dream camera system have, based on your needs?

Super fun everything, of the easier things I quoted I wonder if a semi-portable camera with peltier junction cooling with water cooling on the peltier has had any application for some specific field. Power hungry, but maybe not impossibly heavy or expensive. I would love mini-hdmi over micro hdmi, ...

Re: What features and comforts would your hypothetical dream camera system have, based on your needs?

I know there are liquid lenses, but are there liquid filters? A filter that could continuously adjust across the visible range (and beyond) would allow a monochromatic sensor to be exposed at any wavelength. Yeah, there are liquid crystal continuously adjustable bandpass filters. The OD is often pr...

Re: Mitutoyo 10x 0.42 M Plan APO HR lens adventure

If you watch closely, you can see in each video that the barrel of the objective has several small holes that are filled with white stuff. Yeah, you are right. I have seen people with a DIY setup to do this. They have this circular thing with several micrometers poking in. My guess is that the adhe...

Re: What features and comforts would your hypothetical dream camera system have, based on your needs?

If we are talking about a theoretical camera here, I will have some fun then. Sensor: I want a circular sensor with 42mm in diameter, pixel size should be about 3.6x3.6um. That would translate to something along the lines of 107mp? A hybrid shutter, this means both global and rolling, with a bit dep...

Re: Diatoms: Kittonia elaborata (edit: stereo added)

PS. I have a *tiny* cleaned sample of the Russian diatomite that K. tripedia is found in. Sadly, I only found two broken examples in the whole sample (enough for two moderate-sized strews). One of the finds at least has two of the "stalks" intact - but it only acts as confirmation that the species ...

Re: Mitutoyo TAGLENS Liquid Tube Lens for Ultra Deep DOF

AO is not new at all, microscopists are only playing catch-up in the recent decade, compared to the astro-imaging field. Eric Betzig put it pretty well but his remarks were quite crude, so I will not quote him here. 14DZiERF9c8 At 2:32, without his usual swearing. There was an extended lecture where...

It does autofocus and extended depth of field imaging (processed?), and it is able to compensate for common aberrations.

Re: Macro rail assembly

The process is actually really easy, you just need a good rail. THK makes some nice ones, so does Suruga Seiki, Misumi and PI. They are all very expensive, however, I have seen them go for the $50 mark sold by people who do not know what they have. If you are okay with manual, then most large stages...
