ZNA‑W‑488 LD‑Pumped 488 nm Laser
The ZNA-D Series 473 nm Blue Laser is a rugged, high-stability LD pumped all-solid-state CW laser engineered for demanding environments. Designed with robust sealing, compact dimensions, and excellent beam quality, the ZNA-D Series delivers reliable performance even under harsh operational conditions — including operation at pressures down to 0.02 kPa. With exceptional beam profile (TEM00, M² <1.2), high pointing stability, shock resistance, and IP-rated housing (IP67/IP65), the ZNA-D Series is ideal for collimation, medical treatments, scientific experimentation, optical instrumentation, laser displays, and industrial integration.
Features
- High Beam Quality – TEM00 transverse mode with M² <1.2.
- Excellent Stability – RMS <2% / <3% over 4 hours.
- Rugged & Sealed Housing – IP67 (S version) / IP65 (N version).
- Wide Temperature Range – Up to 0–60°C (S version).
- High Shock Resistance – 7g lateral / 15g vertical (6 ms).
- Ultra-Compact Design – Beam height only 19 mm.
- Low Pressure Capability – Operates down to 0.02 kPa.
- Flexible Modulation – TTL or Analog (1 Hz–30 kHz optional).
- Low Power Consumption – <30 W.
- Long Lifetime – Up to 10,000 operating hours.
