Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
MLL-DP-640-B: Collimation benefits from a stable, focusable source. 640 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (Near TEM00 (TEM00 optional)) informs waist size and propagation.
MLL-DP-640-B: 640 nm emission determines compatible optics, coatings and detectors for Laser medical treatment. The catalogued beam parameter (Near TEM00 (TEM00 optional)) helps predict how the source will focus and propagate through the instrument.

Technical FAQ
Cooled method (Water Cooled): WCH-580 · Operating temperature (℃): 10-35. Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Transverse mode: Near TEM00 (TEM00 optional) · Beam divergence, full angle (mrad): <3.0. Size the downstream optics from the stated beam diameter and divergence rather than from the aperture of the housing, and confirm the polarisation state before specifying isolators or polarising optics.
Share wavelength, operating mode, output power or pulse energy, linewidth or pulse width, delivery, control, and safety requirements and we will qualify the matching configuration and lead time.
