TTL Modulation <10kHz (PLB/PLG/PLA Series)
PL Series | Compact TTL-Modulated Laser Diode Modules
Ultra-compact lasers with 5 V power and TTL on/off control up to 10 kHz
The PLB, PLG laser diode modules are perfect for applications requiring slow modulated beams in small diameter package sizes. The PL series feature several standard wavelengths between 635 nm and 850 nm with output powers ranging from 1 mW to 10 mW. The PL series provides predictable wavelength and power stability. Each laser module comes pre-collimated with a user-adjustable focusing lens.
PLB — 8 mm Diameter (Ultra-Slim)
- Ø: 8 mm Length: ~46 mm
- Power: 5 V DC Control: TTL on/off ≤ 10 kHz
- Optics: Pre-collimated, user-focusable aspheric glass
- Best for: tight probes, handpieces, compact fixtures
PLG — 10 mm Diameter (Compact)
- Ø: 10 mm Length: ~46 mm
- Power: 5 V DC Control: TTL on/off ≤ 10 kHz
- Optics: Pre-collimated, user-focusable aspheric glass
- Best for: embedded vision, scanning heads, portable tools
PLA — 12.6 mm / 0.5″ Diameter
- Ø: 12.6 mm (0.5″) Length: ~50.8 mm (2″)
- Power: 5 V DC Control: TTL on/off ≤ 10 kHz
- Optics: Pre-collimated, user-focusable aspheric glass
- Best for: standard ½″ clamps, easier heat-sinking, production fixtures
Place stable, focusable light exactly where your system needs it. The PL family delivers continuous-wave (CW) output with low-frequency TTL gating in the smallest barrel sizes we offer—perfect for alignment, targeting, machine vision aids, and embedded OEM instruments.
