Laser detection cards provide instant, fade free operation for simple alignment, location and safety purpose visualization of laser light. They are made of durable 0.8 mm plastic and have photosensitive region 44 x 54 mm that extends all the way to the three edges of the cards to facilitate use in laser alignment procedures. Full dimensions of the cards are 86 x 54 mm.

  • Covering Visible and Near-IR spectral ranges
  • Plastic, credit-card sized (86 x 54 mm)
  • Large sensor area (54 x 44 mm) extending to the edges

VIS & IR Detection Card

990-0846 Laser detection card has a sensitive active region which can be used to visualize weak power laser beams, to detect beam reflections or scattered IR laser light. Proper function of this card requires charging it with visible/day light before use. Additionally, because emissions from the active region are not persistent, the user must move the card around for optimal brightness of the beam spot.

  • Emission band: 580 - 750 nm
  • Emission peak: 660 nm
  • Absorption band: 400 - 640 nm and 800 - 1700 nm

NIR Detection Card

990-0847 Laser detection card does not require charging. The emission is persistent even when used in CW applications in a darkened room. In addition, when the active region is used in a darkened room with sufficiently bright source, the fluorescence from the activated photosensitive region can be seen through the back side or the photosensitive region can be activated by illuminating the back of the card. This is especially useful for aligning the overlap of two beams.

  • Emission band: 520 – 580 nm
  • Emission peak: 550 nm
  • Absorption band: 790 – 840 nm, 870 – 1070 nm and 1500 – 1590 nm
