TH-PF Series

TH-PF Series flat lights for high-power strobe lighting.
Uniform diffuse light for backlight illumination.

  • Increase the speed of liquid level and shape/appearance inspections.
  • Freely adjustable flash timing enables strobing within the exposure period of the camera.
  • Solves your xenon flash lamp problems.

Features of PF Series

“Extreme Power” Strobe Lights

The PF Series high-power strobe lights achieve greater output power than conventional products when used with the dedicated control units.
Improve productivity on high-speed inspection lines in a wide range of applications.

Using the Flash As a Camera Shutter

The high-power strobing enables instantaneous imaging.

Eliminating Image Blur

Horizontal Blur
Conventional product:Long exposure period and insufficient brightness result in image blur.The image is blurred in fast moving production lines.
PF Series:High brightness allows for short exposure time and reduces blur.Applicable to fast moving production lines.
Vertical Blur
Conventional product:Adjusting aperture to compensate for dim lighting reduces depth of field. Vibration causes image blur.
PF Series:High brightness allows for smaller aperture and increased depth of field.Image unaffected by vibration.

Freely Adjustable Flash Timing

You can use the lighting delay time setting of the control unit to adjust the timing of the flash to be within the exposure period of the camera.
