Built on a compact and stable platform with optimized thermo-mechanical properties, the Cobolt Dual Combiner provides a permanently aligned beam overlap. The very small dynamical tolerances of the beam overlap (<20 µrad/oC) combined with a robust and compact platform make any adjustment at installation or over time unnecessary. The Cobolt Dual Combiner™ is intended for use in a laboratory environment as a drop-in replacement to Ar+ & Kr+ gas lasers or for integration as OEM component module for use in demanding bioanalytical applications such as flow cytometry, laser scanning cytometry, DNA sequencing and confocal microscopy. The foot-print of the device is only 195x65 mm, and the two laser lines can be addressed individually through RS-232 communication. Examples of attractive line-combinations that can be offered with the Cobolt Dual Combiner™ are: 491+515 nm, 491+457 nm, 491+561 nm or 561+594 nm.
