Key features
532nm green wavelength — 5000m visible range
The Laser-303 emits a 532nm green beam. Green at 532nm is visible to the eye at lower power levels than red laser wavelengths. The source states a visible range of 5000m to the naked eye at night. Output power is not specified in the source specification and has not been estimated or added by Aetheo.
Key switch — key protection
A key switch with key protection (described in the source as a child safety lock equivalent) is fitted to the body. The key must be present and turned to activate the device. Activation time once engaged: ≤0.001s. This feature prevents unintended activation when the key is removed.
External focus — adjustable beam width
The external focus mechanism allows the beam width to be adjusted by rotating the head of the device. The degree of focus adjustment and minimum spot size are not specified in the source.
Hard anodised aluminium — 23×168mm — 18650 battery
The body is hard aluminium with an anodised black finish. Dimensions: 23×168mm. Battery: 18650 rechargeable at 1000mAh, DC 3.7V. A charger for the 18650 battery is included in the package. No certifications are listed in the source specification.
