How Do You Choose a Semiconductor Laser? Quick Selection Guide + Recommended TO5.6 Laser Diode
Published: 2026-07-24 14:52:08 Views: 58
Semiconductor laser diodes are essential light sources for industrial sensing, LiDAR and laser printing. Many engineers waste time picking mismatched models. We summarize 4 simple selection standards, plus a mature industrial product: HGLD-790TO5.6-ZSP-10mW from HAUCORE.
1. Match Wavelength & Power to Your Application
- Particle detection / laser printing: 780–800nm, 10mW low power
- 3D sensing: 850/905nm
- Optical communication: 1310/1550nm
Our HGLD-790TO5.6-ZSP-10mW fits particle monitoring and scanning perfectly: 790nm central wavelength, rated 10mW, max output 12mW.
2. Check Temperature Resistance for Industrial Scenarios
Ordinary laser diodes only work 0–60°C, while industrial equipment needs wider temperature range.
HGLD-790TO5.6-ZSP-10mW supports -40℃ ~ 85℃ operation, with hermetic TO5.6 sealing and strained quantum well chip for high heat resistance.
3. Confirm Packaging & Built-in Monitoring PD
TO5.6 is the most universal standard package, compatible with most circuit fixtures. This model has integrated monitor photodiode (LD positive, PD reverse), supporting real-time power calibration.
4. Verify Beam Divergence for Optical Collimation
Asymmetric beam (35° vertical × 6° horizontal) is easy to collimate with microlens arrays, improving light utilization for detection modules.
