The Non-Brand Anti Blue Light Test Pen & Laser Pointer tests blue cut lenses and identifies counterfeit currency. A 5mW output provides a visible beam across 10-100 meters. This tool uses a 405-532nm wavelength for optical verification and feline interaction.
Key Features
- 3-in-1 Beam: 405-532nm wavelength for optical testing, currency verification, and pet play. One device handles three distinct field tasks.
- Metal Housing: Copper and aluminum body with APC line circuit control. Resists physical impact and manages voltage spikes.
- Currency Verification: Yellow mark indicator for instant genuine banknote identification. Detects fake notes even under heavy road dust.
- Beam Calibration: 1.0-18mm spot diameter with 5mW power output. Maintains focus over a 100-meter maximum range.
- Low Power Draw: DC 3.0V working voltage with under 350mA current draw. Runs efficiently on standard portable battery cells.
Frequently Asked Questions
How to use blue light test pen for glasses?
Shine the 405nm beam through the lens onto a testing card. If the card remains white, the lens blocks high-energy blue light.
Does the blue light pen test actually work?
The 532nm laser reacts to UV420 protection and security fibers in money. It provides immediate visual confirmation of material properties.
