Mystery optoelectronical parts

[HomoSovieticus]

Hello, maybe someone can explain me what you see in the pictures ? I know it has something to do with optoelectronics. I couldn't find any better forum to ask. Internet doesn't give any information on them. Maybe someone is interested in them ? They are super super heavy items 1 box is like >30kg easily. See the links below.

What the heck ?? I also own some other interesting pieces without any knowledge what it might be used for ? Like these(and if you are into guessing or have ever worked with things like these I'm super interested in hearing whats up with these things) The big ass metal stand seems like some laser positioning system or whatever ? And interestingly enough it seems that it was never used... :

Whats the matter with big round glasses ? Filters ? What kind of ? How to find out ? Check it out here :

Thanks for helping to resolve these mystery items.

The second picture shows the LOMO logo (https://en.wikipedia.org/wiki/LOMO)
Perhaps it's possible to ask them what the model OP-23 is, or with some luck find something in their catalogues?

I have sent e-mail to LOMO. It was very nice idea. I somehow thought that LOMO doesn't exist anymore. What is q switched laser ?

I don't really understand how that can be any type of laser ? It seem like pure piece of metal, no diodes, no wires, nothing ? Any other ideas ?

Now a question for you : What the word offtopic means ?
