Application context
Why this design is used
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
Laser ranging
DPS-1535-P: 1535 nm emission determines compatible optics, coatings and detectors for Laser ranging. The catalogued beam parameter (≤15) helps predict how the source will focus and propagate through the instrument.
Optical communication
DPS-1535-P: 1535 nm emission must sit inside the fiber-component passband used for Optical communication; connector polish, fiber mode, linewidth and back-reflection tolerance should be specified as one optical interface.
Target indication
DPS-1535-P: 1535 nm emission determines compatible optics, coatings and detectors for Target indication. The catalogued beam parameter (≤15) helps predict how the source will focus and propagate through the instrument.
System integration
Integration and compatibility
Use these checks to connect DPS-1535-P to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Cooled method: Conduction · Operating temperature (℃): -20~60
- 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
- M2: ≤1.3 / ≤1.5 · Beam diameter (mm): ~1
- 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.
