9. More to come…

Production models will be lighter and smaller with custom sensor circuit boards, reduced wiring, custom case, etc.
 
There is a scintillator in the Helium Ion Fluorescence Spectrometer, it converts the back-scattered particles into the visible light range which is then displayed as a spectrum. The spectrum characteristics can then be mapped to known elements.
 
Yes, He-4 detectors have good pulse-width discrimination between gammas and fast neutrons, although plastic scintillators are generally reckoned to be best for efficiency. Not so good for thermal neutrons, where various types of lithium-doped glass scintillators are better.

Since neutrons are electrically neutral particles, they are mainly subject to strong nuclear forces but not electric ones. Therefore, neutrons are not directly ionizing and usually have to be converted into charged particles before they can be detected. Generally, every type of neutron detector must be equipped with a converter (to convert neutron radiation to common detectable radiation) and one of the conventional radiation detectors (scintillation detector, gaseous detector, semiconductor detector, etc.). Fast neutrons (>0.5 MeV) primarily rely on the recoil proton in (n,p) reactions. Materials rich in hydrogen, such as plastic scintillators, are best suited for their detection. Thermal neutrons rely on nuclear reactions such as the (n,γ) or (n,α) reactions to produce ionization. Materials such as LiI(Eu) or glass silicates are therefore particularly well-suited for detecting thermal neutrons. The advantage of 6LiGlass scintillators is their stability and their large range of sizes.

It's a huge subject to try to summarise in a few lines, and the exact measurement requirements (flux, direction, and energy spectrum) are important to decide what detection method(s) should be used. A general-purpose device would have limited applicability for many use cases.
 
What about adding in a Touch Microscope?

You can also add in a traditional Electro-Optical Field Microscope to see minor details and record it the info for later.

Lidar/Radar sensors for local 3D environmental imaging?
 
^Impressive and interesting. 3 µm x/y-axis resolution and 0.3 µm z-axis resolution, so not as good as an electron microscope or the best optical microscope. x/y-axis resolution is 0.2 nm for a transmission electron microscope (TEM) and 10 nm for a scanning tunnelling electron microscope (STM). The best optical microscope can manage 0.2 µm, which is 500 times better than the human eye. An atomic force microscope (AFM) has a resolution of about 0.1 nm. For comparison, atomic radii typically range from about 0.1 to 0.2 nm. For casual use, this would be handy though.

To the wish list of capabilities, one might add RNA and DNA sequencing.

The thing about a handy, all-purpose device is that it's never going to excel at any one thing. A specialised piece of lab equipment is always going to beat it.
 
Yes - I was going to mention...
Do NOT try to make it a Jack-of-all-trades. Create specialized versions.

There's a good reason not to try to cram too much functionality into a single system of such modest size.
 
I liked the early Lytro camera housings.

You might get everything into the ST II/ALIENS type devices...as large as they are.

That touch microscope... maybe an object can be rotated into it and be read.

I liked the near flat saucer of the FASA Refit Enterprise and have often wanted a scaled up version.

What about advanced electronic sensors to cover:
Smell
Taste
Hearing

We already have the VISOR to cover the Visual and near Visible Spectrum.

We have Tricorders that cover most EM waves

We can have advanced Microscopes.

I agree, specialised add-on modules for different applications would seem the way to go for a tablet-based device. The main limitations are the processing power and memory of the tablet and the power delivery and bitrate capabilities of the data cable. USB4 supports up to 5A at 48 V (240 W) and 80 Gbit/s symmetric or 120 Gbit/s asymmetric.

Star Trek has two varieties of tricorder (at least) and they are limited in ability (depending on the plot requirements). McCoy can only do so much with his medical one before he can get the patient back to sick bay. Spock has more sensors at his disposal on the Enterprise's bridge than he does out in the field. I think there are also specialised engineering tricorders, but were they ever described in detail?

As for medical tricorders, in the real world there is the rHEALTH One, which was reportedly going to be deployed on the ISS. It's a little bulky, but perhaps could be miniaturised somewhat.

Battery power is always an issue.
This original tablet could barely run 4 hours in reduced CPU and backlight mode with no USB devices plugged into it.
One of the first upgrades was to add batteries to it inside the electronics enclosure on the back, which are connected to the internal batteries and charge controller.
I upped the battery capacity to 36,000mAh from 8,000mAh @ 3.7V, this should give over 12 hours working time depending on which combination of sensors are turned on, with the backlight on full (outdoor operation is assumed) and all 4 processors running at top speed.
There is room to add more but I thought that was good to start, and you have to consider the weight.
 
Another suggestion - maybe try to find a partner to develop a package more suited to what you are trying to create.

I would suggest it be a bit thicker than an iPad - this gives more room for a better power source and could allow you to embed the core of the sensor package inside the 'Tricorder'. Could also allow a slightly tougher package and could allow a better protected screen.

While this concept will obviously be mainly for Science/Medical applications - trust me - the military will get interested if only for the Medical version. They will insist on DOD Spec construction and electronics.
 
I do have tentative plans for production.
There is a lot of work going from prototype to production so I have 3 Phases.

Phase 1: Finish designing and testing the prototype along with designing and prototyping some of the sensor packages.

Phase 2: Create an LLC company and crowd fund equity to get to the production stage

Phase 3: Create a crowd fund with someone like Indigogo or Kickstarter for advertising and sales

You probably couldn't call it a "tricorder" without negotiating with CBS Studios Inc., who hold the trademark, I believe.

Here's a link to the US register of filings for that name.

Search on "tricorder" if it has timed out.

Gene Roddenberry intentionally did not copyright the word "Tricorder" and hoped that people would make real ones, however you can't make it look like any CBS tricorders from any of it's productions.
Most of the trademarks at uspto.gov refer to a "toy" or a "medical device" both of which it is not.
My Phase 2 has a legal review period to make sure everything is ok.
Negotiating with CBS is also an option.

Well, Roddenberry is long dead and the suits tend to get greedy. You would be attempting to profit off corporately-owned IP and I expect they would want their cut. Even if the trademark does not cover the specific functionality of your version, I expect they could tie you up in the courts and bankrupt you through legal shenanigans if they felt so inclined. Also, you should not confuse copyright with trademark. They are different things.

I'm also not getting the market for this device. People who want to cosplay would be happy enough with a cheap non-functional replica from the various series. People who want a proper scientific instrument might not want to buy a device from an unknown manufacturer. Serious career scientists don't rank "cool geek value" above fitness of a device to perform a specialised function at work. Your market would seem to be the intersecting set of Star Trek fans and science professionals who want to show off to other such people - such as the main guys portrayed on The Big Bang Theory. If so, it should look more like a device from one of the Star Trek shows.

It should also be open source so users can tailor as they see fit for their needs. If it were going to run Linux, it should be open source anyway. If it runs iPadOS or Windows, you risk alienating the subsets who hate Apple or Microsoft. I've never met anyone who hates Linux - apart from the controversial excrescence that is systemd.

ETA: I expect there are quite a few people working on such handheld devices, where convenience makes sense for obtaining quick results. Here's a video on the topic from 5 years ago about a medical version:
