New MeoStar B1 Plus Binoculars (1 Viewer)

That's a good development. Using the light transmission graphs from the 2018 catalogue I speculated in another thread that the improvement in light transmission from changing to MeoLux should be about +2% at 550 nm, +3% at 650 nm and +4-5% at 450 nm for a complex binocular. Hopefully they'll make the same change to the S2 scope.

Henry:
I suppose we should all should know is what the term MeoLux means.
So, it would be good if you would help by telling us more on how you found those large differences in transmission numbers.

I am not sure if Meopta has a primary market. They strive to make a very good bino that will leave the user with no regrets. I have the MorStar B1 10x50's and they are IMHO better than my other Euro bino's that cost more than double.
I know the new for 2020 Air bino's have confused a lot of folks but I believe they will find their nitch and again, not leave the customer with any regrets.

My numbers, Jerry, but they come from sources in the 2019 Meopta catalogue. There's a graph showing the difference between rifle scopes using MeoLux vs MeoBright and in the technical data at the end of the catalogue there are Day (550 nm) and Night (480 nm) transmission specs for all Meopta Products. Maybe the 2020 catalogue will have revised transmission specs for the Meostar binoculars after the coating upgrade.

Thanks for the chart, those numbers now make sense.
I would think this would bring the new Meopta near the transmission of the newest Alpha's.

So regarding the Meopta Air due to come out in May,.... has there been any info on when the B1+ is due for the market?. I think the Air models are being promoted to Birders while the B1+ to the other popular sport.

Very cool, I've always been a fan of the Meostar series. I actually prefer the old, knobby armor but if this is anything like the Cabela's Euro series armoring, it is very tactile and durable.
I was looking to buy a new pair of binoculars soon, I've not bought anything in months...

Meopta advise that due to Covid-19 a realistic date for B1 Plus reaching dealers is September/October and this might be subject to change depending on how the virus progresses.

Thanks Lee, just have to get through another month, then perhaps some normalcy, fingers crossed.

I think it helps in these times to be optimistic, we will get over this as we have in the past. I wish the rainy weather would leave us for a while on the east coast.

Spring flowers are showing over here, Blackbirds are building nests, many species are singing and Hermann has seen Swallows already. This is optimistic: so you are right, let's all join nature.

Here is the diagram referred to by Henry.

Hi Lee and Henry,

Been interesting reading this thread as I know so little about Meopta except for the fact they have obviously a far far better product range than people like me would have realized. (Lee, I knew from you that they must meet exacting standards.)

So I became curious and wondered if you can explain the meaning of the shaded bar area in the graph Lee supplied. I am used to seeing Gijs's data but will admit freely to never looking beyond the figures themselves as a comparison between binos. I shan't feel patronized if you have to spell it out in words of one syllable! :-O

Looking today I managed to find a couple more Plus images at: https://www.armietiro.it/12313
They show:
- a x32, and
- a 15x56 HD

And for comparison an image of the current B1.1 15x56 HD from Meopta's site
(the RA colour is probably unchanged, just a difference in the software settings used to make the images?)

Tom the clues are the words in the bar at the bottom with Twilight on the left and Midday on the right. During daylight the eye is most sensitive to light at 555nm hence the right-hand margin of the grey band. The left-hand margin leaves me a little puzzled because max sensitivity here is normally given as 500nm (hence Gijs normally gives transmission data at 555 and 500) but the left margin is at 480. Anyway the grey band pretty much indicates the wavelengths to which the human is eye is most sensitive at twilight and during daylight.
