Application context
Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
Laser medical treatment
MBL-U-491-SF: 491 nm emission determines compatible optics, coatings and detectors for Laser medical treatment. The catalogued beam parameter (TEM00) helps predict how the source will focus and propagate through the instrument.
Flow cytometry
MBL-U-491-SF: 491 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<3%, <2%, (<1% optional@Water Cooled)) helps keep measured intensity changes attributable to the sample rather than source drift.
DNA sequencing
MBL-U-491-SF: 491 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<3%, <2%, (<1% optional@Water Cooled)) helps keep measured intensity changes attributable to the sample rather than source drift.
System integration
Integration and compatibility
Use these checks to connect MBL-U-491-SF to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Cooled method: Air Cooled/ Water Cooled
- Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
- Beam parameters at the output
- Transverse mode: TEM00 · M2: ~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.
