【SG822】🔥⏰Powerful 450nm 5500mw Laser Pointer with 5X Beam Expander

Features:

✔️High quality, stable performance

✔️Perfect for creating various visual atmosphere, sky pointing, illumination, indicating, alignment, sky pointing or other professional usages

✔️High - grade aluminum alloy casing is solid and durable

✔️Low power consumption, long battery lifeBuilt with a rechargeable batteryCompact and lightweight, easy to carry

✔️Laser Chip: Imported semiconductor laser source.

✔️Beam Shaping: FAC (Fast Axis Collimation) technology corrects fast-axis divergence and minimizes beam distortion, producing a uniform, parallel beam.

✔️Optical Components: Coated aspherical collimating lens eliminates spherical aberration; multi-layer anti-reflective coating reduces optical loss, suppresses back-reflection, and protects the laser chip.

✔️Heat Dissipation Module: Solid oxygen-free copper (OFHC) heat sink (21mm x 40mm) for efficient heat extraction from the laser chip.

✔️Thermal Interface Material: Indium foil metallurgical bonding ensures zero-volatility heat conduction—avoiding optical contamination caused by silicone grease outgassing—while providing stable thermal resistance and buffering against thermal cycling stress; industrial-grade pump-level packaging enhances the LD's long-term lifespan.

✔️Housing Construction: Precision-polished stainless steel main housing, fully CNC-machined with a high-gloss finish; impact-resistant, corrosion-resistant, and featuring a rugged industrial aesthetic.

✔️Product Positioning: A high-power, portable industrial blue laser—distinct from DIY products assembled with silicone grease—suitable for optical experiments, long-range targeting/calibration, and material ignition testing.

Warm Tips:

The optimal operating temperature for the laser is 25°C, and the maximum case temperature should not exceed 55°C. Excessive operating temperatures will accelerate aging; the laser is a device characterized by high energy consumption, low conversion efficiency, and significant heat generation.

Disclaimer: Never point your laser at aircrafts or cameras, as this can get you into legal trouble.

Warm Tips:

(1) Do not let the laser beam enter the eye. The laser beam is harmful to the eyes, every contact may lead to permanent damage.

(2) Do not look directly with your eyes or with binoculars or any other device to observe the laser beam.

(3) Please remove the battery from the laser pointer when you are not using it.

(4) Do not point the laser beam at planes, people, animals, etc.

(5) It is best to use it for less than one minute each time, otherwise the motherboard may burn out easily.
