Re: New Raf Adapters Arrived

Very nice. I always use Raf for my adapters. Great quality and he is good to deal with. That must be the only other Zoerk MFS adapter I've seen outside of their old product literature. I got one years ago, when I bought a cheap 'Hasselblad to M39 adapter' from a second hand dealer here in the UK. Wh...

Re: Blog on UV and other aspects of microscopy and imaging

Congratulations! Very nice to see how the normalized tranmission curves and emission curves match so well at every peak. Your project is especially nice in that you have tested and quantified everything at every step. That's extremely rare, most of us don't have the intrumentation to do it. I hope ...

Re: Blog on UV and other aspects of microscopy and imaging

A bit of an update on the UV transmission microscope build. Everything is now done, and I have been able to do transmission imaging down at 313nm, which is about the limit of where I can get to with my current camera and light source. Link to the latest update here - https://jmcscientificconsulting....

Re: fluorescence metoo

First thing, check the spec sheets of the different bulbs. They could be different manufacturers versions with the same specs, which SHOULD be ok to use interchangeably, but I'll admit it is not something I'd want to do without knowing more about the bulbs. If not, then best to just use the original...

Happy New Year everyone. The UV microscope build is coming along. For the latest on how I modified the binocular head see here - https://jmcscientificconsulting.com/uv-microscopy-modifying-the-binocular-trinocular-head-part-ii/ I've used UV fused silica components to replace the glass parts in the r...

Re: Full spectrum fluorescence macroscape

Nicely done Lou. I enjoy going round the garden with a UV torch (I have a 15W 365nm one) at night and taking photos. This was the cut end of some Acaccia logs, taken using a Schott KV-418 filter on the lens (to ensure no UV gets through, as my Canon's internal filters do not block all the 365nm ligh...

Re: Is anyone doing UV transmission microscopy?

A bit of an update. I've been gradually pulling together parts for this build and now have what I need to complete it, so hope to have it up and running sometime early 2021. Will be able to image down to about 300nm with the camera and light source I have, however with an alternative camera and ligh...

Re: Blog on UV and other aspects of microscopy and imaging

In case you are interested in a crazy 10x 0.37 UV (365nm) "objective" with a gigantic field size and perfect field flatness, this just came up on eBay today: https://www.ebay.com/itm/193756315611?ul_noapp=true This is quite unique. If nothing else, it is full of UV-transmitting lenses made from exo...

Re: Blog on UV and other aspects of microscopy and imaging

My UV microscope build is coming along. The latest post summarises the work to date and brings together links to the different parts to it. Also I've swapped out some of the original Olympus optical components for UV fused silica now, and I share the initial testing of that. Here's the link - https:...

Re: Question about window on the underside of Olympus trinocular head

Little bit of an update on this one. As shown above both the prism and the glass window block the short wavelength UV, which means that they will be no good when I am doing UVB imaging. I've taken the plunge and ordered a replacement circular window in UV fused silica. This leaves the issue of the p...

Re: 1st attempting at modifying a condenser

Thanks Lou. It's proving to be a lot more involved than I (naively) thought. However I'm gradually working through it.
