New visualizer form
Specialists of RPF "Luminofor" Corp. have developed plastic visualizators in the form of rods:
- Rod dimension 119*3 mm (detection zone dimension 30*3 mm);
- Rod dimension 157.8 *8.8 mm (detection zone dimension 15 *8.8 mm).
The advantage of these visualizers is the small size of the detection zone and the presence of a long handle, which allows them to be used in small-sized laser setups. Due to their compactness, the rod-shaped visualizators easily fit into the smallest camera of the device.
Peculiarities:
- high sensitivity to laser emission;
- general and convenient;
- budget.

New type of visualizer
As part of the research work carried out by the RPF "Luminofor" Corp., the type of the visualizer IKV-G, which has green luminescence in the spectral range of 900-1085 nm, was modified. The new type of visualizer IKV-G has a wider visualization range, which is in the range of 800-1600 nm. The advantage of this visualizer is that it does not need "precharging" with any light source (for example, infrared or ultraviolet). The IKV-3M visualizer has stationary luminescence when exposed to IR radiation.
