For buyers
Please make sure that your microscope is compatible with the objectives listed by ID microscope-cameralovelove before purchasing.
Listed lens types / long-neck objective lenses
Please make sure that the microscope is for the LB (Long Barrel) series (1X to 100X oil) with a focal length of 45 mm and a mechanical barrel length of 160 mm before purchasing.
Objectives and microscope brands can be used even if they are not the same.
This means, for example, that Olympus objectives can be attached to Nikon, Zeiss, Leica, Leitz, etc microscopes.
Incompatible Microscope / Please check.
If you have a microscope with a short-neck objective lens with a focal length of 36.65 mm or an objective lens that is compatible with infinity correction, you can attach it to the nosepiece, but you cannot observe it.

* About the diatom preparation used in the objective lens test *
It is mainly tested with a diatom preparation developed for performance testing of dry objective lenses and for testing microscope illumination.
This diatom preparation is tested with an extremely reliable diatom test plate that is also used by major optical equipment manufacturers.
The 12-13 putamen is mounted around diatoms, which are easy to use for lens testing. The main species are Nitzschia, Pleurosigma, Stauroneis, Pinnularia, etc.
It supports a wide range from low magnification objective lenses to oil immersion areas. It also supports the limit performance check of high magnification objective lenses with a numerical aperture of 1.4. Since this product is mounted with an encapsulant with a slightly low refractive index, it has a low contrast and has been tested with a preparation that is ideal for training in speculum technology.
Diatoms are mounted with the utmost care using a blue plate slide glass (0.9 mm thick) with few surface defects and a cover glass of 0.170 ± 0.005 mm.
*About the quality of the diatom slide used*
When examining traditional preparations from an optical point of view, the thickness of the cover glass, the thickness of the mounting medium, the focus shift due to the difference in the height of the diatom, and the foreign matter and devitrification of the mounting medium make it unusable as a reference for the differential interference method. It is also true that there were many problems such as It goes without saying that it is desirable to supply inspection plates of uniform optical quality, as inspection plates cannot be inspected correctly if they have defects. After examining these problems, we developed a method of arranging diatoms directly on the surface of the cover glass and encapsulating them directly, making it possible to manufacture a completely new quality test plate.
We test the quality of the objective lens by observing it under the above environment.
I observed it with the lens for sale and left it in the image.
Focuses on the cuticle diatom.

If you don't know the accuracy of the photo uploaded by Ebay ID microscope-cameralovelove
Scientific name: Try searching on Google for Cymbella.
You can see that it is a more accurate observation photo than most of Cymbella that comes up a lot on Google.
Ebay ID microscope-cameralovelove is saved in JPEG when saving the first observed image.
If you save the image in JPEG and upload it to the product description on Ebay, it will be a little less clear than when observed by the human eye.
So when you look at it in person, it looks sharper than the image you see uploaded in the product description.
I think that the observed photos are one of the indicators for measuring the condition, so I wanted the buyer to be aware of this fact.
Thank you.
For buyers, confirmation points of the objective lens

If the image is actually bad when the product arrives, I would like to ask you to confirm.
Is it really the seller's objective that you are not satisfied with your observation?
Try rotating the eyepiece.
Try rotating the objective lens from the nosepiece.
Try moving the slide slightly. What about dirt not only on the front side of the slide but also on the back side?
Is your microscope's viewfinder dirty with dust?
Try cleaning them.
Condenser centering,
Are the capacitors too low?
If the position of the condenser is low, various dirt can be seen.
Position the condenser as high as possible.
If it is raised too high, it will not be in focus and the contrast will be lowered or unclear.
The smudges in the image may be on the field lens or on the internal mirrors below the field lens.
Do you regularly maintain your microscope?
More to the point, have you seen the instruction manual for the microscope you have?
There are many other things I would like you to check.
for example
Is it because there is not enough light? If the amount of light is small, dirt is easily reflected.
Is the aperture setting wrong? "Contrast is also affected."
It is that.
Please check these and send me a message regarding the condition of the lens.
Even though I'm strictly referring to
This is because the way an image is captured is completely different depending on the difference in observation techniques, knowledge, and experience.
Depending on the equipment used for observation, the image will look different.
In fact, I was able to observe and shoot neatly to some extent as shown in the photos I posted.
Buyers are purchasing after confirming the product description.
Please do not unilaterally return goods, make accusations, or demean the seller.
Even if you send me a message, please be gentle and give me a valid message.
There is simply no reason or grounds for it, and the image quality is worse than you expected, so returning it will also be a problem.
I think you will continue to have more trouble.
Because no matter what objective you buy, if there is a problem with your observation, you will not be able to observe it satisfactorily.
In short, I want you to find the reason why you cannot observe satisfactorily.
We would like to sell our products to our customers and other customers in a stable manner.
Thank you for reading this far.
Thank you.
