The tarm 20 FB4 is made in Germany and is a compact show laser system that is ideally suited for top professional laser show applications of any kind. It is built with the latest RTI semiconductor laser modules that are specially designed in a way to keep spot size as well as divergence equal on both x- and y-axis. This is significantly advantageous over solutions with a very good divergence on one axis, but a bad divergence on the other. The laser modules inside the tarm 20 FB4 are different - the spot size and shape is equal for all colors and on both axis!

The beam specifications of the new tarm 20 FB4 are given with only ca. 5.0 mm diameter and 0.7 mrad divergence - which applies to both axis, so it's an actual value not an average and provides higher quality results than specifications with mixed calculations. The extremely small beam diameter allows for the use of very small mirrors, which results in reduced inertia and thus very good scanning performance.

The tarm 20 FB4 impresses with a guaranteed RGB output power of 20'000 mW. Great visibility is achieved with the new RTI Semiconductor Laser modules (RSL) with special wavelengths for increased visibility: 3'400 mW / 637 nm for a very bright red combined with 5'650 mW / 525 nm green and a strong blue laser module with 13'340 mW / 455 nm. The 525nm green provides a warmer green tone than the 520nm diodes and has increased visibility.
These new RSL modules with their extremely low divergence and homogenous beam shape make the tarm 20 FB4 a top professional laser system. The extremely small beam diameter of only ca. 5.0 mm allows for the use of small scanner mirrors which leads to reduced inertia and higher scan speeds. This is especially important, as the tarm 20 FB4 can be used for any kind of laser show application: Super sharp beams and vivid colors for large scale concerts and festivals but also a perfectly matched beam for crisp graphics.

The RTI Semiconductor Laser modules are maintenance free and do not come out of internal alignment.
The standard scanners can be run at a maximum of 45kpps @ 8° and a maximum scan angle of 50°.

The powerful tarm 20 FB4 is suitable for indoor and outdoor show laser applications at concerts, festivals and other huge events. Demanding graphics projections or projections over long distances are possible without any problems, due to the extremely good divergence.
