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!

✔︎ Choose from two types of LED light

(left) Ring light (right) Bar 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.

・The depth of field can be adjusted to focus on a height difference of approx. 10 mm
・ 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

When using a magnifying glass:
・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.

4K digital loupe can:
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
