Conversion screens, also known as sensor cards, make invisible laser radiation visible. Conversion screens are held as sensors directly in the laser beam. There are versions available for low, medium, and high power lasers.
Our conversion screens make your laser visible in the ranges from 250 nm to 600 nm and from 700 nm to 1700 nm.
We carry the world’s largest range of conversion screens, covering different power levels and the complete spectral range from UV to NIR. We will gladly assemble a selection of basic equipment for your laser laboratory.
Our large range of cards, which can convert invisible laser radiation to visible light, is constantly being updated. In addition to our new LDT-008R, which covers the range from 800 nm to 1600 nm, there are a number of other new items.
High Power Cards
All high power conversion screens (LDT-1064BG, LDT-1064C, LDT-1064CL, and LDT-1064M) now exhibit the model number on the handle.
The new conversion screen with high power cards is our LDT-1064CL. Thanks to its slim 100 x 30 mm hand piece, it can be held in the most remote corners of your laser without your fingers getting too close to the laser beam. The active area measures 30 x 30 mm. The technical specifications are identical to LDT-1064C.
The high power IR conversion screens are now produced in-house and, when ordered in reasonable batch sizes, are also available in custom sizes.
All stated power levels refer to use in daylight. In darkened rooms significantly lower minimum power levels apply. Also, some stated maximum power levels can be exceeded two- or three-fold if exposure occurs only a fraction of a second or the card is moved quickly. Due to the limited heat capacity no card is suited for permanent exposure to a laser beam. They should be slightly moved. This also improves the image quality and certain low power models bleach less during movement.
Nevertheless, if a card burns please avoid eye contact and do not inhale the fumes or particles in the active area. The chemicals of the up conversion processes inside our cards – which are responsible for the visible glowing – are not poisonous, but are also not positive for your health either.
A special feature of the LDT-1064M is that it makes the transversal modes of our 100 W Nd:YAG laser visible.
