Description

Technical Field

[0001] This utility model belongs to the technical field of experimental equipment for microbiological research, specifically relating to an anti-reflective petri dish imaging device. Background Technology

[0002] In microbiological research, petri dishes are essential tools for observing and analyzing microbial growth. Petri dishes are typically made of plastic or glass and are widely used for culturing and observing bacteria, fungi, and other microorganisms. However, during actual photography, the material of the petri dish often produces reflections, resulting in blurry colony images. This reflection not only affects image quality but can also lead to errors in quantitative microbial counting and species identification, thus impacting subsequent growth and metabolic studies.

[0003] The clarity of colony images is crucial for microbiological research. Clear colony images help researchers accurately assess the growth status, quantity, and species of microorganisms, providing reliable data support for quantitative analysis and classification. Furthermore, colony images can be used to monitor the growth dynamics and metabolic characteristics of microorganisms, thereby advancing research and applications in related fields. Currently, some solutions exist for the reflection problem in petri dish photography, but most methods still have limitations. For example, using special light sources or filters can reduce reflection to some extent, but this often requires complex equipment and is costly, and inconvenient for on-site use. Therefore, a new imaging device is urgently needed to effectively solve the reflection problem. Utility Model Content
