tarm 18 Pure Diode RGB Laser with ShowNET
 
The tarm 18 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 18 are different - the spot size and shape is equal for all colours and on both axis!
 
The beam specifications of the new tarm 18 are given with only 4.5 mm diameter and less than 0.9 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 4.5 mm mirrors, which results in reduced inertia and thus very good scanning performance.
 
The tarm 18 impresses with a guaranteed RGB output power of 18'000 mW. Great visibility is achieved with the new RTI Semiconductor Laser Modules (RSL) with special wavelengths for increased visibility: 4'000 mW at 637 nm for a very bright red combined with 4'500 mW / 525 nm green and a strong blue laser module with 10'500 mW at 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 18 a top professional laser system. The extremely small beam diameter of only 4.5 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 18 can be used for any kind of laser show application: Super sharp beams and vivid colours for large scale concerts and festivals but also a perfectly matched beam for crisp graphics.
