UV and IR sensor cards (also known as transducer cards) are indispensable tools in any optical laboratory. They are ideal for the adjustment and visualization of invisible laser radiation. Even low laser powers of a few μW can be displayed with the aid of the cards. High-temperature cards are available for higher laser power levels; their sensitive surfaces consist of temperature-resistant ceramics. Special types of sensor cards for Nd:YAG or CO2 lasers as well as printed cards and adhesive films complement the product range.
