Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
UV-D-355: 355 nm emission determines compatible optics, coatings and detectors for Semiconductor wafer inspection. The catalogued beam parameter (<4.5) helps predict how the source will focus and propagate through the instrument.
UV-D-355: Grating interference lithography benefits from a stable, focusable source. 355 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (<4.5) informs waist size and propagation.
UV-D-355: 355 nm emission determines compatible optics, coatings and detectors for DOE direct writing. The catalogued beam parameter (<4.5) helps predict how the source will focus and propagate through the instrument.
UV-D-355: 355 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<1%) helps keep measured intensity changes attributable to the sample rather than source drift.

Technical FAQ
Cooled method: Water cooled · Operating Temperature (°C): 10-35. Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Beam divergence, full angle (mrad): <4.5 · M2: <1.5. 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.
