Modern way of creating microphotographs/microform?

The enlarger route sounds like a nice poison. Digital enlargers themselves are crazy $$, but maybe I can do the phone thing in the negative holder as a first try.
Is there a way to tell if an enlarger lens is designed to pass UV? I don't have an enlarger yet...and it's been a while since I've used one.
If I am aiming to have the image projected exactly 35mm, what type of lens would I be after?
Those 8mm movie lenses?
Also, when it comes to flipping the lensboard, does that offer optical reduction if the lens is flipped?

Is that how the cyanotype microform was created in my link above?

No, I don't think so. Are you familiar with Microfiche? The originals are already reduced in size, and the cyanotypes were made via ordinary contact printing methods such as you might do at home using the sun as a UV light source.

As for how such things were miniaturized in first place, I found these tidbits:

If you want to create enlarged cyanotypes, the trick is to create a negative of the desired size, then contact-print in the usual manner as per yet another video:

I suspect that UV-light enlargers would not be simple or cheap, hence the popularity of contact printing.

I realized it was a contact print after posting...my mistake!
Yes, microfiche/microform is basically what im after, but using a digital image directly inputted, and not making printed transparency sheets if I'm using an enlarger.
The only way I can think of is putting a phone/ipad or something in the negative holder.
I have seen those planetary cameras before, not sure how easy it is to get one for a good price.
I am curious to know if anyone out there has tried creating microforms using an enlarger, and what their setup is.

I don't know what lens I would need to get an image 24x36mm/same output as a 4k+ film recorder (but analog)

I think I need a 35mm lens for an enlarger, is this correct if I want a 35mm area?

Since it's a direct digital UV light source I want (no transparencies), I guess a phone or ipad wouldn't work.

@Bronson Dugnutt If photographing a LCD screen/monitor with a regular 35mm camera, would cyanotype-in-camera work at all, or would the exposure times be extremely long?
I hear you need quartz lenses for the UV to get through, do I have that right?
What lens would offer both UV transmission/fast exposure and ability to shoot a screen at proper angle/ratio?
But also, a monitor isn't going to emit UV...so im not sure if there is a solution here either?

Thanks for the link!
One thing I'm thinking about since I'm after a live feed digital UV image is using a transparent screen (somehow) like a transparent oled or lcd, and shining UV through it. But the resolution would likely be crap. For an enlarger.
