3-5mW Green Laser Module (APC)

3-5mW measured optical output as supplied. Normally the output can be adjusted between 0 and 150% of the original output.

This module uses a photodiode feedback circuit to give a stable output.

Specification

• Wavelength : 532nm +/-5nm
• Output Power : 3-5mW
• Operating Voltage: 3.0V
• Connections: Positive = red /blue wire or brass body, negative = black wire or spring.
• Current: <280mA controlled by APC driver circuit
• Dimensions: 12mm diameter x 42mm brass body, 60mm long including circuit
• Pattern: 1mm minimum spot, <5mm @5metres (divergence < 1.5mRad)
• Operating Temperature: 10 – 30°C

Notes on Operation: These modules have a built-in constant power (photodiode feedback) drive circuit designed for a 3.0V power supply, (output can be adjusted using the on-board potentiometer).

Wire connections are fragile and best reinforced with silicone or epoxy sealant and heatshrink, see photo 2.
