Terahertz Optomechanics
Setups for transmission or reflection measurements
• Transmission: versatile sets with 3D precision-stages
• Collimated beam (2 mirrors) or focussed beam (4 mirrors)
• Reflection: compact head (4 mirrors)
• 3 mm spot size
TOPTICA offers four different sets of optomechanics, designed for the most common beam-path configurations. For transmission-mode experiments, three rail-based assemblies produce a collimated terahertz beam (2-mirror setups), or an additional focus (4-mirror setup). For applications that require a reflection geometry, a compact, handheld module generates a focus at the location of the sample.
