The early version of TWX-1 had metal elastic pressure plates around the prism, which were later replaced by cement in order to compromise costs.......

The first thing I noticed was the fixing method of the body panels. The body number starts with 1970 and is fixed with bolts (red arrows) instead of riveting. Pay attention to the thread (green arrow). 11.jpg What's even more surprising is the "screw hole sealing process", “ a surprising composite o...

Compatible with original BH and Vanox AH microscopes. This will not fit BH2 or Vanox AH2/AH3. By machining a bottom condenser dovetail groove (not included in the price), it can fit into the BH2 of Olympus while retaining the rotating polarizer. If you are interested in the adapter, I can process it...

Okay, considering that I have been exposed to multiple TWX-1 microscopes in the past year. (From 1970 to 1984). I plan to compare the TWX-1 produced in different years (from structure to process) here. I don't have much exposure to antique microscopes. To satisfy my curiosity, I will ask questions. ...

intermediate tube and slider $1500!

Is that so?

There should be in the Chinese market, but due to weight, transportation costs will exceed the product itself

What component are you referring to?

Gorgeous footage! I wanted to share this paramecium as well - it's from a young microscopist on my Discord with a BH2 and a 40x SPlanApo. He's using an iPhone, though! https://www.reddit.com/r/microscopy/comments/14l9va0/fair_view_of_parameciums_contractile_vacuoles/ Are you sure it's an APO object...

Hey y’all, I want to get an AH-AAC condenser for my Olympus vanox AH since it comes with swing out filter holders, but it’s not widely available. Anyone know if a CH series or similar condenser would fit and has filter holding capabilities? Thank y’all for your guidance! It’s helped me progress eve...

With all due respect, the first thing to focus on is whether there is room for maneuver in the NFK focal length.

As far as I know, at least 5mm

Exquisite images, especially for non biological professionals

PS: The flash is designed to freeze motion......

I prefer to use 60 frames of video and extract images, which saves a lot of hardware preparation work

As far as I know, the ideal dark field effect should be to maintain a suitable distance between the stopper and the grating. That is, the position of the prism and PC ring.

Interesting project, thank you

I sell old microscopes from China and receive feedback from buyers in the United States without charging any taxes.

as the acme of perfection

But considering the complex and massive equipment, I decided it would be better to sit on the sidelines

From my perspective as an amateur player, the more significant difference is FOV.

Okay, I'll put a terrible picture here
This is a diamond abrasive (6.5 microns), and for this semi transparent material with single refraction, an electron scanning microscope should be the only choice.

I cannot guarantee whether the following 'English' is logical: High numerical aperture reflective condenser and dark field illumination provide the preferred method for observing and capturing very small collections of particles or colloidal suspensions, even if the particle diameter is significantl...

The three most common delay plates generate optical path length differences across the entire wavelength range (between 530 and 570 nanometers), half wavelength (260-280 nanometers), or quarter wavelength (137-150 nanometers).

so.......

Please allow me to correct: OEM products are not "reverse engineering", they are authorized transfer production activities (in order to obtain a price advantage). And use the original company brand, right? Of course, OEM has promoted the technological progress of latecomer industrial countries, in s...

but I have no idea how/where that Company sits in the grand scheme of Chinese manufacturing.

In my humble opinion, all OEM products serve as transitional products in the layout of China's manufacturing industry, and establishing independent brands is the long-term solution.

"This one had the circular stage BH2-SRG with permanently attached centering bolts, and it clips onto the same round stage holding frame used for several biological stages (the BHT stage and nose turret are easy to remove for different uses). Olympus also made a larger circular stage BH2-SRP, which ...

To non original English speakers language issues on the fine details of what is expressed may be the cause of misunderstanding (I’m Dutch). On my BH2’s switching from NFK2.5 setup with the standard Photomicro adapter L to the MTV-3 adapter with NFK3.3 requires fine adjustment of the focal plane (z-...

To be honest, I feel very confused :oops: Why is it that some people cannot understand? This is just showing the applicability of different photography eyepieces :roll: In that case, please allow me to waste some more space :geek: 屏幕截图 2023-04-22 215650.jpg From left to right: NFK2.5 direct projecti...

As is well known, the BH2 series camera system is designed for film cameras, so in my humble opinion, there is no 'most suitable digital camera accessory'. Additionally, these three images are of the same specimen, same objective, and same camera, so of course they can be compared. Allow me to inclu...

I would like to use this comparison chart to illustrate the problem. The Chinese translation in the picture is as follows: _20230421091149.jpg From left to right NFK 2.5 direct projection 120% NFK 3.3 Direct Projection 100% NFK 3.3+PMTVC 194% Equipment: BHS NIC SPlanc 40X Which setting do you prefer?

Pricing is $200 (excluding shipping), please contact me through personal information

This app hasn't been updated for many years, to be honest, I quickly deleted it.

It can quickly deplete the camera battery

If you want to use stacking, it is recommended to use a shutter line.

Actually, I prefer to use the 4K video function, which can maintain photo accuracy every frame.

If you accept a quotation of $300 (excluding shipping costs), you can contact me via private message.

No, it exists.
