    For buyers
    Please make sure that your microscope is compatible with the objective lens I am listing before purchasing.
    Listed lens type Short neck objective lens
    Please make sure that the microscope is for a short-neck objective lens with a focal length of 36.65 mm and a mechanical barrel length of 160 mm before purchasing.
    Long-neck objective lens focal length = 45mm, mechanical lens barrel length = 160mm LB (Long Barrel) series or infinity-corrected microscopes can be attached to the nosepiece. cannot be observed either.
    *Tools used to test the objective lens*
    microscope body Olympus BHB
    1.25 condenser
    MTV-3, Relay Lens NFK 2.5X LD 125,
    USB microscope camera 18 million pixels
    Olympus LBD-2N Blue Filter
    *About the diatom preparation used for testing the objective lens*
    It is mainly tested with a diatom preparation developed for testing the performance of dry objective lenses and microscope illumination methods.
    This diatom preparation is tested on a highly reliable diatom test plate that is also used by major optical equipment manufacturers.
    12-13 putamen are mounted around the diatom, which is easy to use for lens testing. The main species are Nitzschia, Pleurosigma, Stauroneis, Pinnularia, etc.
    It supports a wide range of applications from low magnification objective lenses to oil immersion areas. It also supports limit performance checks of high-magnification objective lenses with a numerical aperture of 1.4. Since this product is mounted with a mounting medium that has a slightly low refractive index, it has low contrast and has been tested with a preparation that is ideal for training microscopy techniques.
    A soda plate slide glass (thickness: 0.9 mm) with few surface defects and a cover glass of 0.170±0.005 mm are used, and diatoms are mounted with great care.
    *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.
    Cuticle diatomaceous
    Scientific name: Cymbella
    Taxonomic class: Genus
    Eyes: Cymbellales
    Family: Cymbellaceae
    Phylum: Heterochondrial algae
    If you don't know the accuracy of the photo I uploaded
    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.
    When I save the first observed image, I save it as JPEG.
    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.

    As the chaos of the pandemic calms down, Japan Post will be able to ship to more countries.
