Seek Compact Pro - Telescope
« on: May 09, 2020, 05:32:13 pm »
Hello!

I've just finished up my Thermal Telescope prototype and thought I'd share it with you all. I'd welcome any feedback as this is the first optical device I've ever made.

Lenses used:

- 38mm dia Trumpf ZnSe lens (negative meniscus - 190.5mm FL)
- 20mm dia MCW ZnSe lens (plano-convex - 38,1mm FL)

Camera:

- Seek Compact Pro FF (iOS)

Extra Parts:

- Female to Male Lightning adapter
- Many 3D Printed parts. All bespoke.

Now, this is a prototype and I will be refining it some more, including redesigning the parts to improve the overall design. Was having a nightmare getting the images inline without been humongous so just attached for you to take a look at. Also, a small clip of a pigeon too https://youtu.be/TX-Pc-LAoUw

The magnification is approx 7.75x, which is great for what I want! Simple slide action can be used for focusing if needed.

Areas I'm aiming to improve:

- Image circle size. I'd like to maximise the image circle so that it covers the entire sensor. This could be a limitation to these lenses as their job is to focus the laser down to a small point minimising waste (hence the negative meniscus).
- Mount stability.
- Include amount for an iPhone 5s so I can mount the whole package together.
- Better fixing for the camera. Currently held in place with tape :-+

That's about it for now, hope you find this somewhat interesting! :-+ And a major thank you to @winternight95 for the lenses & @Fraser for the heads up!

Cheers

Niall

Which image can you get, if you place lens just in front of seek compact lens?! Can you see smd chip with 38mm dia Trumpf ZnSe lens?

If you are asking what the close focus is like then pretty good. Though that lens is overkill, a 20mm works great and can focus down to about 25mm.
