NIR Non-destructive inspection

Contaminant detection (Food)

C15333-10E, sample image

Sample: Coffee beans
Contaminant: Stone
Wavelength: 1200 nm
Illumination: Reflection
Camera: InGaAs line scan camera C15333-10E

Stones that are difficult to detect in visible images because of their similar size and hue to coffee beans can be easily detected in SWIR images.

Contaminant detection (Food)

C15333-10E, sample image

Sample: Rice grains
Contaminant: Stone (red) / Plastic (green)
Wavelength: 1450 nm
Illumination: Reflection
Camera: InGaAs line scan camera C15333-10E

Contaminants that are difficult to detect in visible images because of their similar size and hue to rice grains can be easily detected in SWIR images.

Damage inspection

C15333-10E, sample image

Sample: Apple
Wavelength: 1450 nm
Illumination: Reflection
Camera: InGaAs line scan camera C15333-10E

It is possible to detect damages on apples that are difficult to distinguish visually.

Liquid level inspection of sealed containers

C15333-10E, sample image

Sample: Smoothie
Wavelength: 1450 nm
Illumination: Transmission
Camera: InGaAs line scan camera C15333-10E

The liquid level in sealed juice or yogurt containers can be seen with SWIR imaging.

Container inspection

C15333-10E, sample image

Sample: Instant noodles
Wavelength: 1200 nm
Illumination: Reflection
Camera: InGaAs line scan camera C15333-10E

The contents of sealed plastic containers, such as instant food, can be checked.

Semiconductor wafer pattern inspection

C15333-10E, sample image

Sample: Si wafer
Wavelength: 1100 nm
Illumination: Transmission
Camera: InGaAs line scan camera C15333-10E

The internal pattern of Si wafers can be observed.
