X-Cite® Optical Power Measurement System
The X-Cite® Optical Power Measurement System includes both the X-Cite® XR2100 Power Meter and the X-Cite® XP750 Objective Plane Power Sensor. Designed for measuring optical power in watts at the specimen level, the X-Cite® XP750 has a low, sleek profile that fits on the microscope stage and offers the versatility of measuring power output from an X-Cite® illuminator or any other epi-fluorescence light source.
The X-Cite® XR2100 and X-Cite® XP750 allow you to measure the optical power at the specimen level enabling consistent and repeatable illumination throughout research experiments, and also assist in equipment set-up and troubleshooting. With a PC interface and "Power Snapshot" tool, data can be easily stored electronically for complete experiment records.
For the ultimate in repeatability, the X-Cite® XR2100 will calibrate the X-Cite® exacte illuminator using power data from either the light guide input port or the X-Cite® XP750 at the objective plane.

Testimonials
- "The XP750 is destined to become an important staple in the toolbox of every investigator who is doing quantitative work that demands absolute repeatability in terms of excitation output. This unit is far superior to standard power meters because it fits perfectly into a slide holder and positions the light sensor at the objective focal plane."
- Michael W. Davidson
The Florida State University
- "Much of our research depends on quantitative fluorescence microscopy analysis over long time periods. The X-Cite® XP750's design makes it easy to routinely measure the exact amount of excitation light delivered to the specimen at any given time point."
- Damir Sudar
Lawrence Berkeley National Laboratory
- "The X-Cite® XP750 is very easy to use and would be a valuable tool for any researcher wanting to measure fluorescence intensity."
