Description

Technical Field

[0001] This utility model relates to the technical field of microscopic image imaging equipment, specifically a full-width thin-film polarized microscopic image imaging instrument. Background Technology

[0002] A microscope is an optical instrument consisting of one or more lenses, and it is a hallmark of humanity's entry into the atomic age. Microscopes are primarily used to magnify tiny objects visible to the naked eye. Microscopes are divided into optical microscopes and electron microscopes: modern optical microscopes can magnify objects up to 1600 times, with a minimum resolution of half the wavelength. The mechanical tube length of domestically produced microscopes is generally 160 millimeters.

[0003] An optical microscope consists of an eyepiece, objective lens, coarse adjustment knob, fine adjustment knob, slide clip, light aperture, diaphragm, revolving nosepiece, mirror; stage, arm, tube, base, condenser, and aperture.

[0004] The drawbacks of traditional microscopes are that they have a small field of view and require stitching together full-frame images, which is inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a full-width thin-section polarized light microscopic imager to solve the problems mentioned in the background art. By applying the imaging technology of a microscope to this instrument, the full-width image acquisition effect of thin sections is achieved. The field of view is 25-100 times that of microscope imaging, while the clarity is higher, thus greatly saving the acquisition and identification time of rock thin sections and other thin-section images.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A full-width thin-film polarized microscopic imager includes an instrument base, an LED light source, a polarizer and a polarizer rotary stage located above the instrument base, a transverse slide, a longitudinal slide, a thin-film stage, a plaster test plate and an upper rotating device mounting plate, a switching slide and a reflective light, a module mounting plate and an XY module connecting plate for supporting and connecting the transverse slide and the longitudinal slide.

[0008] The instrument base is equipped with a back mounting plate in the vertical direction. A camera focusing slide is mounted on the side of the back mounting plate. The camera focusing slide is connected to the acquisition camera and lens through the camera mounting plate and can slide up and down to adjust the focus.

[0009] Two sets of polarizing mirrors and polarizing mirror rotating stages are arranged correspondingly, located at the top and bottom. Each polarizing mirror is set on the polarizing mirror rotating stage and can rotate or move forward and backward. The horizontal sliding stage and the vertical sliding stage are respectively connected to the thin film stage, allowing it to move left and right or forward and backward. Two reflective lamps are arranged on both sides of the thin film stage, and the reflected light is used to illuminate the thin film.

[0010] The polarizing mirror can be electrically rotated, the horizontal sliding table can slide left and right, the vertical sliding table can slide back and forth, and the polarizing mirror can move forward, backward, and rotate.

[0011] The module mounting plate is vertically fixed to the instrument base and connected to the XY module connecting plate, which in turn connects to the transverse slide and the longitudinal slide respectively.

[0012] Furthermore, the plaster test board is mounted on the upper rotating device mounting plate, which is then connected to a switching slide. The switching slide controls the forward and backward movement of the polarizing mirror and the plaster test board located above.

[0013] The switching slide is mounted on the back mounting plate via a bracket.

[0014] Two reflective lamps are provided, located on either side of the thin-film stage, and the reflected light is used to illuminate the thin-film object.

[0015] Furthermore, it also includes support columns, of which four are provided and vertically installed on the instrument base.

[0016] There are two sets of polarizing mirrors and polarizing mirror rotary tables. The upper set of polarizing mirrors and polarizing mirror rotary tables is fixedly connected to the back mounting plate; the lower set of polarizing mirrors and polarizing mirror rotary tables is fixedly connected to the four support columns.

[0017] In use, this invention places a thin slice under a single polarizing microscope, crossed polarizing microscopes, and a reflecting mirror. A high-resolution camera captures full-frame images of the slice, resulting in high-definition microscopic images under these conditions. A gypsum test plate is placed in the system, and the optical path difference of the plate is utilized to aid in identifying first-order interference color minerals (such as quartz and feldspar) by observing the sequential changes in mineral interference colors. The polarizing microscopes located above and below have synchronous rotation functions at different angles, allowing for the acquisition of multiple interference color characteristic images of the slice from different orientations under crossed polarizing microscopes. This enables the interference colors of minerals and other components that are in the extinction position in a single image to be revealed after rotation at a certain angle. In this way, all mineral components in the entire slice can be observed and identified.

[0018] Compared with existing technologies, the advantages of this invention are: its novel and unique structural design applies microscope imaging technology to achieve full-width image acquisition of thin sections, with a field of view 25-100 times larger than that of a microscope, while offering higher clarity. It solves the global technical challenge of the small field of view and the need for stitching full-width images inherent in traditional microscopes, thus significantly reducing the acquisition and identification time for rock thin sections and other thin sections. This allows for the rapid imaging and digital preservation of numerous thin section microscopic images, playing a crucial role in the intelligent identification of thin sections.
