New range of highly directional backlights for machine vision
30 Jan 2018
TH2-PM lights are available in white, red (635 nm) and blue (465 nm) light versions, which provide the versatility to accommodate a wide variety of inspection requirements.
Eight different sizes are available:
|27 x 27 mm||83 x 75 mm||43 x 35 mm||100 x 100 mm|
|51 x 51 mm||140 x 105 mm||63 x 60 mm||160 x 120 mm|
Each size has white, red and blue options, making 24 models to choose from.
These backlights can be used in a variety of applications. By producing a silhouette image of a solid object or imaging ‘through holes’, they can be used for dimensional measurements or part presence verification. The high directionality of the light gives binary images with sharp edges for measurement.
This directionality also provides enhanced contrast when imaging detail in transparent materials such as fine scratches or cracks in glass or liquid fill levels. Different transparent materials may absorb light of a specific wavelength, so the use of red or blue LED illumination may allow normally transparent materials to be viewed in silhouette for measurement.
The TH2-PM lights have been designed for easy mounting. Tapped holes for installation are included both on the side and bottom of the supporting frame.
- Flat, high output backlight
- Improved illumination efficiency and brightness
- Many different sizes and colours combinations
CCS was founded in Kyoto in 1993 and released its first LED light for the machine vision market in 1994. Since then, the company has expanded and now is one of the world’s largest suppliers of LED illumination with offices in Japan, China, Singapore, Belgium and the US.
