For manufacturers, appearance inspection is very important to check for defects such as dirt, foreign matter, burrs, and scratches adhering to products. However, do you have problems with visual inspections using a magnifying glass, such as "inspectors are very fatigued" or "it is difficult to share what they have seen"? In recent years, automatic inspection machines have been on the market, but their introduction costs are high thus they are not yet readily available.
Therefore, in this article, we will introduce a digital loupe with 4K image quality that is easy to implement at a low price.
Reasonable price in spite of 4K image quality!
Shodensha ｜ What is 4K digital loupe?
Shodensha's 4K digital loupe is equipped with a 4K camera, zoom lens, LED lighting, and 4K monitor as standard. While low-cost, visual inspections with clear 4K image quality can be started right away.
◎ Very clear 4K image quality
◎ Excellent color reproducibility
◎ Easy to project on a monitor for viewing by multiple people
◎ Data can be recorded
◎ Low price that is easy to implement
Just so clear! Beautiful!
Edges and scratches can be emphasized
✔︎ Clearly see every detail
The most attractive feature of the 4K camera is its high resolution, which shows the smallest details clearly, allowing observation in high-definition quality even with 2X digital zoom.
✔︎ Choose from two types of LED light
Ring light type｜The entire area looks bright and clear because the light is evenly shone from above.
Bar light type ｜Because the light is shone at an angle, unevenness is emphasized. It can be moved in three directions (up and down, front and back, and angle), making it ideal for inspecting scratches in such as metal working.
✔︎ With measurement function
Angle / 4-point angle / Perpendicular line of 3 points specified / Two-point area measurement (length, width, perimeter, area)
Elliptical area measurement (length, width, perimeter, area) / Two-point circle measurement (diameter, perimeter, area) / Distance between two circles, etc.
There're more! Features of 4K digital loupe
・ Easy zooming by mouse operation
・Zoom in from a wider field of view than with a regular microscope.
・ Zoom in while maintaining a deep depth of field.
Are you using a magnifying glass for appearance inspection?
Visual inspection using a magnifying glass has the following issues
・Fatigue on the operator is high.
・Multiple people cannot observe at the same time.
・It is difficult to share and record what each operator sees.
Clear 4K image quality｜Reduces the burden on the operator
Monitor & mouse operation｜Working in a comfortable posture
Large screen for viewing｜Easy for multiple people to view at the same time
Save images and video data｜Speedy sharing of defects
▲ Data storage and playback functions are built into the camera itself.
Observed defects can be saved on the spot as images or videos, allowing data to be shared speedily. Quickly implementing the process from discovery to improvement can increase product quality and reduce overall costs.
