Thank you, the lesson is just what I needed to clean my dad's 75 year old Nikon Nippon Kogaku 7X50 binocular.

I took my first pair of binos apart yesterday to address a fungus on the prisms issue. This is a pair of 7x35 11 degree with removable prism plate. I did remove the prism plates from the binocular body to better clean the prisms. Note I was not quite so foolish to remove the prisms from the prism plates. HOWEVER, upon attempting to put the prism plates back I "discovered" that the three screws that hold the prism plate down also seem to play some role in the prism plate tilting as there are grub screws next to each main screw which seem to be causing various tilts when tightening up the prism plate. And it seems that the order in which you tighten the screws to put the prism plate back affects the final tilt of the prism plate. Ok fine, so I put everything back together as best I could and then found my alignment was off. This was fixed with an eccentric ring collimation of the main lenses using stars at night. This worked but presently an interesting observation. Turning the right lens did not improve collimation at all. In fact, all if did was cause the star I was using for collimation to either disappear all together or reappear as I turned the lens. Turning the left lens did work well and allowed collimation for a single star image. However, I read somewhere that messing with the prisms for collimation would reduce the image quality. And the incident where turning the right lens caused the star to appear and disappear makes me think the light path of the prism could be really out whack. Am I understanding that wrong? Which lead to the question, how does one properly re-install a prism plate to get the optimal light path (independent of what might happen later if eccentric ring tweaking is needed). Thank you.

I don't know how to install prisms correctly, because I'm self-taught, but I learned to repair from my mistakes. I can say for sure that it is best to collimate binoculars with the help of adjustment rings on the lenses. I think that your binoculars are not professional enough to pay attention to the prisms.

if the factory produced binoculars with screws on the prisms to make collimation, then there is nothing wrong with this.

What you thinks about japanese Carton prisma 10x50 binocular sharpness?

@StOKRATzoom Ай бұрын

do you want to buy it? what is its price? I believe that these are budget binoculars from the 80s of the last century, so the quality is also so-so. buy new binoculars and you will be happy. for example SVbony SV202 I have a video
