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. 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. 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.

BH2 is basically for long barrel objective lens LB (Long Barrel) with focal length = 45mm and mechanical barrel length = 160mm. However, the BH2 can be used with short-neck lenses if adjusted. Therefore, BH2 users can use this short neck lens. If you don't know how to use short neck lenses with BH2, ask.

Tools used to test the objective lens. MTV-3, Relay Lens NFK 2.5X LD 125. USB microscope camera 18 million pixels.

Resolution test plate (OTK- 01). About the diatom slide OTK-1 used for testing the objective lens. A purified specimen of a large cuticle diatom. The purity is extremely high, and it can be said that it is almost a single-species preparation. This cuticle diatom has a large, puffy putamen, and an extremely delicate structure spreads out, making it an irresistible beauty for microscopic enthusiasts.

OTK uses Pleurax, a high refractive index mounting medium. The color of Pleurax is brown, so it looks like this.

The contrast is clear and the objective lens can be inspected with high precision. It supports a wide range of applications from low magnification objective lenses to oil immersion areas.

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. 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. 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. 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.
