The LU-N4/LU-N4S/LU-N3 are compact laser units that come pre-installed with four lasers (the LU-N3 with three). These laser units support one laser application system, such as TIRF and photoactivation illumination systems and Confocal Microscopes A1⁺ and C2⁺.

• LU-N4/LU-N4S^* Laser Units are equipped with four lasers (405 nm, 488 nm, 561 nm, 640 nm), while LU-N3 Laser Unit has three lasers (405 nm, 488 nm, 561 nm). Setting up is easy, just connect the fibers to the system, as each laser is pre-installed and pre-aligned.
• LU-N4/LU-N4S/LU-N3 is equipped with the newly developed laser combiner, which prevents alignment shift even after long-term use while improving laser output stability.
• The built-in AOTF allows laser power to be independently controlled and modulated.

Dedicated laser unit controllers for different system configurations can be mounted on the laser unit to conserve space.

*LU-N4S is compatible with spectral imaging but not with the Ti2-LAPP system.
