Optics: Advantages of pre-optimized voltage
• Greatly reduces risk of lost data due to improper set-up
• No specialist training or dedicated operator required
• Predictable, reproducible analysis relative to sample type and application
• Saves time and sample
• Attenuation filters (for too-bright signals) give controlled signal reduction
• Predictable fluorescence spillover
