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.
