89 North™ Microscope Automation

PhotoFluor®II High-Powered Light Source for Fluorescence Microscopy

The PhotoFluor® II combines a powerful metal halide lamp with a high-efficiency hot mirror to block the infrared and deliver excellent light output across the spectrum from 340 nm to 650 nm. With a 1500-hour lamp life and a pre-aligned light engine, the performance of the PhotoFluor® often exceeds that of a 100 Watt mercury lamp.

Features

• High output from 340 nm to 650 nm
• Quiet operation with no vibration
• No alignment needed
• 1500 hour lamp life, stable output
• Four‐position neutral density wheel with shutter
• Easy to use display and user interface
• Computer-control via serial interface
• Output of a mercury source
• 5 mm core liquid light guide for high output; 3mm core available
