Phosphor Detection Cards

bulletInfrared To Visible

These heavy duty clear detection cards are great for detecting a wide variety of light sources, aligning laser systems and testing equipment.  The phosphors used are incapsulated inside a 35 millimeter thick card protecting the phosphors from getting damaged from wear.  The cards are quite durable unlike the common paper cards.  Our unique transparent card with a translucent phosphor target, allows you to see behind the card when working with difficult tasks such as aligning a laser device.

Please note that the DC-IRSPG Infrared to Visible detection card uses a storage type phosphor.  The phosphor must be charged with light before use.  Any light can be used though a fluorescent or UV light will work best.  The DC-IRSPG can detect lower power IR sources, but the phosphor loses its charge quickly when illuminated with IR.  Therefore, you should move the card around when detecting the IR source so that the IR beam hits freshly, charged phosphor. The DC-IRSPG can detect a much wider range of infrared beams, 700nm to 1500nm, than the DC-IRUCG, but the DC-IRSPG must be charged before use and once the phosphor is hit with an IR beam, it glows green for a few seconds before losing its charge.

The DC-IRUCG uses a non-decaying, up-conversion phosphor that does not need to be charged.  However, the DC-IRUCG will work best for higher power IR sources.  Most remote controls can be detected with the DC-IRUCG because the LED's are typically 940nm and they are pulsed at high levels.
