Olympus UPlanSAPO 10x 0.40 Microscope Objective UIS2 RMS Lens 25149

  

Appearance:Please check the photo carefully! There's no black seal on the end of the lens, In the case of fluorescence observation, it is described that it affects the photographing. Please judge the performance of the lens by the observed photograph. There are no dirty or scratches that could adversely affect observation.

Since it is a used lens, it is not inspected by enlarging it with a magnifying glass. It has been confirmed with the naked eye under strong light.

There is no balsam separation. There is no haze on inside of the lens. It has no fungus on inside of the lens.

It has a little tiny scratch on the rear lens. Please check the photo carefully! Shown on the photo is everything.

Anything not shown in the picture is not included. Can be bundled with other products.

Items below for details on bundling. Types of listed lenses / objective lenses for infinity correction. 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. Long-neck objective lens LB (Long Barrel) series (1×100× oil) with a focal length of 45 mm and a mechanical barrel length of 160 mm, and a short-neck (with a focal length of 36.65 mm) (Short Barrel) If you use a microscope with an objective lens, you can attach it to the nosepiece, but you can't observe it. Tools used to test the objective lens. Phase difference condenser olympus u-ucd8. USB microscope camera 18 million pixels + C-mount camera adapter. Olympus LBD (BX50 internal 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. 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. So when you look at it in person, it looks sharper than the image you see uploaded in the product description. 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. 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? 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. Is it because there is not enough light? If the amount of light is small, dirt is easily reflected.

Is the aperture setting wrong? 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. 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. In short, I want you to find the reason why you cannot observe satisfactorily.
