Đèn cảm biến ánh sáng đồng trục Sensing Coaxial Lighting OPX Series

• Highly uniform illumination with a narrow directivity angle

  Coaxial lighting.which is a diffuse light source.light is applied from multiple directions relative to the object, making it difficult to recognize such aspects as fine scratches and slight differences in surface roughness. Also, with shortdistance illumination, direct light from the light source overlaps with reflected light from the half mirror, preventing the inspection surface from being uniformly illuminated.
  With the OPX Series, the directivity angle of the light source is narrow, suppressing the spread of light and allowing for highly directional illumination. Illumination is highly uniform even when applied at short distances.

  

• Ensure a wider illumination area

  With conventional lighting, in order to illuminate uniformly with increased directivity, coaxial lighting was used at a distance from the workpiece. As a result, the illumination area becomes narrow, requiring an increased lighting size. OPX Series lighting offers uniform illumination even from short distances and reduces brightness deterioration of the peripheral areas, ensuring a wider illumination area.

  

• 2.5 times brighter than conventional products

  Thanks to the OPX Series’ narrow directivity angle light source and aluminum casing offering excellent heat dissipation, brightness is 2.5 times that of conventional models.
  Although parallelism and uniformity of conventional models can be improved by mounting LC (light control) film in front of the light source, the LC film reduces brightness by 30%.
  The OPX Series not only offers increased directivity but also brightness 3.5 times that of conventional models with LC film mounted.

Structure

Compact size

• The adoption of SMD-type LEDs allows for a thin light source, greatly reducing the length of the housing. The volume of OPX Series devices is up to 21% less that of conventional models. This allows the lighting to be installed even with compact inspection stages with limited space. In addition, by providing mounting holes on three sides of the lighting, the OPX Series offers an even higher degree of freedom when it comes to mounting.

Sensing lighting with automatic brightness management

• 

• OPX Series devices include Optex’s “FALUX sensing” technology. The built-in photodiodes are used to monitor the brightness in order to provide feedback on brightness deterioration, allowing constant maximum brightness to be maintained for up to around 50,000 hours. The OPX Series also has LEDs and photodiodes for measuring brightness built in to the housing frame of the surface light source, which allows for accurate measurement of luminance without being affected by extraneous light noise
