Description

A portable microscope slide observation box and imaging device

technical field

The utility model belongs to the field of portable microscopy, in particular to a glass slide observation box for a portable microscope and an imaging device.

Background technique

Microscope technology is widely used in clinical examination, scientific research, teaching and other fields. Traditional microscopes are desktop microscopes, which are bulky and bulky.

Traditional optical microscopes are mainly used for the observation of glass slide samples, and their main structures include objective lenses, eyepieces, transilluminators, and focusing structures. Desktop microscopes are generally bulky and inconvenient to move, and are mostly used indoors.

In recent years, with the popularity of mobile phones and the development of optical processing technology, portable microscopes have begun to enter the market. The portable microscope mainly uses the camera of the mobile phone as a part of the microscope. By adding a compensation lens, the mobile phone becomes a microscope that can take pictures of microscopic objects. This type of microscope is generally widely used in jewelry and jade identification, skin inspection, hair follicle inspection, fabric inspection and other fields.

Since most of the observed objects belong to opaque samples in the field of use, portable microscopes used in mobile phones generally use reflective lighting, and lighting LEDs are installed around the compensation lens to achieve supplementary light to the sample. In addition to the usage scenarios mentioned above, portable microscopes can also be used for the observation of traditional slide samples, such as pathological slides, plant specimens, cytology specimens, etc.

However, the packaging box of portable microscopes is generally a disposable carton, and consumers throw away the portable microscope after taking it out and do not use it, and do not participate in microscopic imaging. The slide sample carrier is generally a glassware in the laboratory, which is different from the packaging box of the portable microscope and does not participate in microscopic imaging.

Moreover, the reflective illumination currently used on the market is not suitable for the observation of glass slide samples, because the surface of the glass slide is very smooth, and the image of the lens itself will also be imaged on the image sensor, causing strong glare, resulting in the imaging of glass slide samples. Not clear. There are also some portable microscopes designed with transmitted illumination on the market. Generally, a bracket structure is used to install a light source at the coaxial symmetry of the lens imaging as a projected transmission light source. Although such a structure solves the problem of glass slide observation, it limits the use of reflective illumination observation, and requires the introduction of an additional LED light source, which increases the use cost of portable microscopes and reduces the compatibility of reflective imaging and transmission imaging. sex.

Due to the inconsistent thickness of the glass slide samples, it is usually necessary to adjust the focus when observing the glass slide samples. At present, all portable microscopes on the market are designed with focusing structures, but most of them use threaded knobs for high focusing. The method has complex structure and large volume, which is not conducive to reducing the volume of the portable microscope.
