Cleanroom Light L3SQ

Dust Finder L3SQ (L-Three-Square)

Dust Finder L3SQ can visualize any defects and dust on the surface very well. We can see the minimum size of dust in 10μm in the best conditions (e.g. in the dark surroundings, on flat surface, etc.)

Size (Light Part): 223㎜×30㎜×31㎜
Weight: 270g

Brightness Adjuster

The brightness adjustment function allows you to adjust the light's brightness depending on the size of the particles you want to see.

MIN

Dim light to see only big size particles.

MAX

Bright light to see small size particles.

Optional
Green Filter To make it easier to see particles.	Cover Needed when setting green filter to the light without stand. To protect light from the gap between the light and the filter.	Stand To adjust height and angle of the light.
Flexible Arm To adust the light to the best angle to see the particles.

Dust Finder L3SQ can visualize dust more efficiently than normally-used LED Stand. Moreover, we counted the dust on silicon wafer by [RACCAR : Coarse Particle Counter] and found that Dust Finder L3SQ can visualize even the particle smaller than 30μm (RACCAR can count the smallest particle at 30μm)
