Features

660 nm red diode laser optimized for fluorescence – Ideal for fluorescence imaging, cell sorting, flow cytometry, confocal microscopy, and other bio-photonics applications requiring a stable red excitation source around 660 nm.
High spectral quality with narrow linewidth – Central wavelength 657–663 nm with typical 0.7 nm FWHM spectral linewidth (down to 0.2 nm min), supporting efficient excitation of common fluorophores and precise spectroscopic work.
Up to 110 mW fiber-coupled output power – Typical output power of 90 mW (up to 110 mW max) delivered through multimode fiber, comparable to leading 660 nm OEM diode modules used in life science and industrial systems.
Excellent power stability for long measurements – Typical long-term power stability of 0.1% RMS and 0.5% peak-to-peak over 8 hours at constant body temperature, reducing baseline drift in time‑critical measurements.
Low intensity noise – Intensity noise typically 0.25% RMS (20 Hz – 20 MHz), enabling high signal-to-noise ratio in sensitive detection setups such as photon counting and precision imaging.
Multimode fiber-coupled output for easy integration – Delivered by default with MM fiber and FC/PC connector for plug-and-play coupling into existing systems, microscopes, and fiber delivery lines; other fiber terminations available on request.
Automatic power control (APC) continuous-wave operation – Integrated electronics maintain constant output power in CW mode, compensating for temperature and diode ageing effects for more consistent performance.
High-speed modulation capability – Supports up to 10 MHz modulation bandwidth, suitable for fast on/off gating, intensity modulation, and synchronization with scanning or timing electronics in OEM instruments.
Integrated TEC temperature stabilization – Internal thermoelectric cooler (TEC) tightly stabilizes the laser temperature, improving wavelength stability, power stability, and noise performance versus non‑stabilized diode lasers.
Compact OEM-friendly form factor – Small footprint of approx. 50 × 30 × 18 mm and low weight (~0.12 kg), comparable to compact OEM diode modules used in handheld and benchtop instruments where space is limited.
Simple 5 V DC power input – Operates from a single +5 V DC supply (typical requirement 1.5 A), easily powered from standard laboratory supplies or embedded system power rails.
Low power consumption – Typical electrical power consumption around 2 W (max. 10 W), minimizing thermal load and simplifying system-level thermal management.
Built-in overheat protection – Integrated safety electronics continuously monitor temperature and provide overheat protection, improving reliability in OEM deployments and demanding duty cycles.
Optimized for simple heat-sinking – Typical heat-sinking requirement of about 1 °C/W with an optimum heat sink temperature of 15–30 °C, enabling straightforward mounting on small aluminum or copper plates.
Fast warm-up time – Typical 0.5 minute warm-up from cold start (max 1 minute) for quick system start-up and reduced downtime between measurements.
UART / USB control interface – Digital UART/USB interfaces allow convenient integration with PCs, microcontrollers, and embedded systems for monitoring, control, and automation, similar to advanced OEM laser platforms.
Adjustable optical power range – Optical power can be tuned from near 0% to 100% of nominal output, offering flexibility for different samples and detectors (note: specified performance is guaranteed at factory preset power).
Rugged fiber delivery – Supplied with approximately 1 m fiber length (0.95–1.1 m), providing a robust and flexible beam delivery path for integration into optical tables, instruments, and industrial setups.
Designed for OEM integration – Compact, lightweight, and electrically simple design makes this laser well-suited for OEM medical, analytical, and industrial systems requiring reliable 660 nm excitation.
