Detecting transparent objects

Detection of Transparent Containers

Transparent Container Detection

The Z3D-W20 wide angle diffuse reflective type sensor is capable of detecting transparent containers.
With normal diffuse sensors, the spot size is small, resulting in chattering due to container surface irregularities and variations.
The Z3D-W20 offers wide-area detection thanks to a large, ø60 mm beam at 100 mm, allowing for detection with a strong resistance to uneven surfaces and product variation.
This enables transparent object detection even in locations where retro-reflective sensors cannot be installed.

Model: Low Cost / Small Type  Z3D-W20




Detecting preform left on the pallet

Detecting preform left on the pallet

Class 2 laser light accurately detects target object.
Light axis adjustment is easy with visible spot light.

Model: Digital laser transparent object sensor type  DR-Q400T




Detecting plastic bottle stuck at a place on the conveyer

Detecting plastic bottle stuck at a place on the conveyer

C-MOS laser BGS sensor BGS-DL detects transparent plastic bottles stuck at a place on the conveyer.
BGS-DL sensor with FGS function detects stably transparent objects.

Model: BGS sensor with C-MOS image sensor  BGS-DL series




Detecting glass plate for automotive

Detecting glass plate for automotive

The retro-reflective type laser sensor DR-Q400T can detect glass plate for automotive windows even if its thickness and width varies.

Model: Laser sensor for detecting transparent object  DR-Q400T




Detecting glass plate in the vacuum chamber through view-port

Detecting glass plate in the vacuum chamber through view-port

Laser transparent object sensor DR-Q150T can detect glass plate through view-port in the vacuum chamber. Reflector sheet for this sensor must be attached in the chamber though, detecting glass plate without expensive displacement sensor can be realized.

Model: Retro-reflective type transparent laser sensor  DR-Q150T




Detecting glass wafers

Detecting glass wafers

NF-TH06 is set its light axis at 45 degrees angle.
Installation in small space is available as the sleeve length of receiver and emitter is different.

Model: Heat resistant sleeve (Side view) type fiber cable  NF-TH06




End Detection of Transparent Film

Transparent Film End Detection

Z3D-W20, which is wide angle diffuse reflective sensor, detects the end of transparent film with detection area more than 10 times the diffuse-reflective type.
This wide detection area enables detection with minimal influence from film wrinkles and variations, even without the use of a reflector.

Model: Low Cost / Small Type  Z3D-W20




Detecting film for binding

Detecting film for binding

Transparent detection type digital laser sensor DR-Q can detect film for binding. It is laser sensor with digital display and detect transparent thin film stably. It also can detect in 4 meter range.

Model: Transparent detection type digital laser sensor  DR-Q series




Instillation bag detection

Instillation bag detection

Detect transparent work piece by using retro-reflective type NF-RR01.
No influences on detection by using built-in polarized filter even if its surface is shiny.

Model: Retro-reflection  NF-RR01




Detect defect seal on instillation bag

Detect defect seal on instillation bag

Digital laser DR-Q (Transparent detection type) detects defect seal on instillation bag.
When it's sealed deviated, DR-Q detects small difference in light reflection.

Model: Laser sensor (Transparent detection type)  DR-Q150T
