Application context
Why this design is used
Applications named on a datasheet for this product line, interpreted against this model’s listed wavelength and beam data.
Optical sensor
PGL-H-445: 445 nm emission determines compatible optics, coatings and detectors for Optical sensor. The catalogued beam parameter (Near TEM00) helps predict how the source will focus and propagate through the instrument.
Measurement
PGL-H-445: Measurement benefits from a stable, focusable source. 445 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (Near TEM00) informs waist size and propagation.
Communication
PGL-H-445: 445 nm emission must sit inside the fiber-component passband used for Communication; connector polish, fiber mode, linewidth and back-reflection tolerance should be specified as one optical interface.
System integration
Integration and compatibility
Use these checks to connect PGL-H-445 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Operating temperature: -10°C to 50°C
- 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: Near TEM00 · Beam diameter at the aperture(1/e2) (mm): ~4.5
- 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.
- Mechanical envelope
- Dimensions of laser head: 77(L)×30(W)×30(H)mm3
- Verify the housing drawing and bolt length before designing a mount. A laser head rarely carries a table thread itself, so the adapter between it and an M6 or 1/4"-20 grid is part of the specification.
