Thumbnail of M15 EEL 661 nm Laser Module – 50-80 mW Visible Red Diode with APC & Adjustable Focus photo 1

Description

The M15 EEL 661 nm Laser Module (50-80 mW) is a high-precision, visible-red semiconductor laser designed for demanding industrial, measurement and alignment applications. Equipped with a built-in Automatic Power Control (APC) circuit, this module ensures stable output power over extended operation — delivering consistent performance even in changing environmental conditions.

An adjustable focus mechanism provides fine control of beam geometry and divergence, allowing operators to tailor the spot size or line shape based on site conditions or system layout. When paired with optional beam-shaping lenses (such as DOE or Powell optics), the module supports a wide range of tailored graphics: parallel lines, cross-lines, dotted arrays or custom patterns.

Flexibility extends to both continuous wave (CW) and pulse wave (PW) operation modes, giving engineers a choice between steady beam for alignment or modulated output for scanning, inspection or metrology tasks. With its robust construction and high output power in the red spectrum, it becomes an ideal choice wherever visible-red light is required for high-precision optical instrumentation.

Whether you’re working in automated inspection, optical alignment, sensor calibration or research prototypes, the M15 EEL 661 nm Laser Module offers the stability, adaptability and optical quality required by professional systems.
