About This Product
■Production of objective lens equivalent products for various microscope manufacturers
Have you ever had the experience of using a microscope objective lens in a system and having to review the system itself because the lens was discontinued earlier than the system? Please use the OBJ series to replace discontinued products or change the specifications of current products. Also, if you are trying to fit an existing microscope unit into the system, or want to increase performance (earthquake resistance, external dimensions, weight, etc.) by removing unnecessary mechanisms, or reduce costs, consider an original microscope. Please use this if you are.
■The handling of a microscope is slightly different from that of other optical systems.
We have compiled a list of the things you need to know when using a microscope, so please take a look.
The various observation methods (illumination methods) for image processing in a microscope are classified as follows.
■Bright field method
The most common illumination method (coaxial epi-illumination) images the reflected light from the sample surface directly onto the imaging surface.
■Dark field method
Oblique illumination that prevents the illumination light from directly entering the objective lens. This illumination images only the diffused light that hits the object on the imaging surface, making it suitable for detecting scratches, foreign objects, and irregularities that cannot be seen in bright field, and for capturing samples with low reflectance.
■Interference method
This method detects interference fringes by arranging a parallel plane plate around the sample, and is suitable for detecting minute scratches, foreign objects, irregularities, steps, etc. in the depth direction that cannot be seen even with the dark field method. .
■Polarization method
This bright-field method uses a polarizer and analyzer placed around the sample to detect the birefringence (photoelastic effect) of the sample, and is suitable for detecting the unique properties of materials.
Classification by imaging method
■Finite correction optical system
An optical system in which the objective lens alone creates an image at a finite position is called a finite correction optical system. This is a common imaging method and most cameras (excluding Olympus) fall into this category. It is necessary to determine the mechanical lens barrel length and optical lens barrel length.
■Infinity correction optical system
An optical system that uses an imaging lens in addition to an objective lens to create an image. Therefore, the mechanical lens barrel length and optical lens barrel length can be set freely to some extent. In order to perform a comprehensive optical evaluation, it is necessary to include the imaging lens in the evaluation, and the influence of the performance of the imaging lens must be considered. (Olympus is one manufacturer that uses this method.)
