Tools used to test objective lenses. Phase Contrast Capacitor 1.25 Phase Contrast Condenser. MTV-3, Relay Lens NFK 2.5X LD 125. USB microscope camera 18 million pixels. 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 preparation used. When the traditional preparation is examined from an optical point of view, it cannot be used as a reference for the differential interference contrast method due to the thickness of the cover glass, the thickness of the encapsulant, the out-of-focus due to the difference in the height of the diatom, and the contaminants and devitrification of the encapsulant. It is also true that it contained many problems.It goes without saying that it is desirable to supply an inspection plate with the same quality microscopically, because if the inspection plate is defective, correct inspection cannot be performed. After studying these problems, we developed a method of arranging diatoms on the cover glass surface and enclosing them directly, making it possible to manufacture test plates of completely new quality. We observe under the above environment and test the quality of the objective lens. I think you can take better pictures of your observations.
