Camera
Bluevision Ltd., Japan develops and manufactures various multi-sensor line scan cameras and single chip area scan cameras. They employ Bluevision Core Technology, an optical signal processing based on prism spectroscopic technologies and handle from visible light area to SWIR (Short Wave Infrared) area by separating different wavelength or area.Those cameras will provide effective discriminant criteria to various non-destructive inspections such as solid state wafer, fruits, food, tablets or other packaged goods or plastic recycling. In addition to those cameras, we supply compact HDTV cameras and Auto Focus HDTV cameras mainly for surveillance or other general purposes.

Spectroscopic imaging
Dispersing in three waves, R G and B (NEW)
The following drawing is a concept drawing of Philips type prism which is mostly
used in 3 waves spectroscopic imaging.
The above sysytem is used in BV-C5400 /BV-C5200, 3 wave RGB line scan
camera and BV-C8300 3 wave RGB VGA camera.
| Model | Dichroic mirror | Trimming filter |
|---|---|---|
| BV-C5400 | B reflection, R reflection | R,G,B each band width filter |
| BV-C5200 | B reflection, R reflection | R,G,B each band width filter |
| BV-C8300 | B reflection, R reflection | R,G,B each band width filter |
disperse the incoming light to visible and NIR wavelengths or 3 specific
wavelength in visible bandwidth, by designing the chracteristics of filters
according to customer's various requirements.
Dispersing in visible light area and Short Wave Infrared light (SWIR) area
The following drawing explains the prism to be used in this spectroscopic imaging.
The camera used this prism is BV-C3500.
Separation of P wave and S wave
The following drawing explains the prism to be used in this spectroscopic imaging system.
The camera used this prism is BV-C3300 and BV-C3350.
Dispersing two different wavelengths in visible or SWIR light area
The following drawing is the prism spectroscopic imaging used in the BV-C3200 line scan camera. In this example, SWIR wavelength is separated at 1290nm for two area.
