The 488nm wavelength is the industry standard for exciting green fluorophores:
The 488nm wavelength represents the primary argon-ion laser line, making it the gold standard for fluorescence excitation. This wavelength provides optimal excitation efficiency for the most commonly used fluorophores while minimizing cellular autofluorescence, ensuring superior signal-to-background ratios in biological applications.
The B488D050-70x40x45-V2 utilizes advanced direct diode technology optimized for 488nm emission. This design ensures exceptional wavelength stability and low noise operation critical for fluorescence applications. The integrated Automatic Power Control (APC) system maintains consistent output power across the entire operating temperature range.
The 488nm wavelength is specifically chosen for its compatibility with common fluorophores and minimal overlap with cellular autofluorescence, making it ideal for life science applications requiring high sensitivity and specificity.
Class 3B laser product. Avoid direct eye exposure. Use appropriate laser safety eyewear (OD 3+ @ 488nm). Follow all safety protocols per IEC 60825-1 and 21 CFR 1040.10. Ensure proper beam containment and interlocks.
