Static & Lighting Chokes
Lighting chokes are used to pass tower lighting voltages across the base insulator of a series-fed tower without appreciably altering the tower impedance. LBA TC-300 general purpose tower lighting chokes are provided for three wire 110/220 VAC circuits. Maximum current is 25 amps. These chokes are rated for peak base voltages to 10,000 volts, and present a typical reactance of +j5000 ohms at 530 kHz. Bypass capacitors are provided on each winding.

Light Measurement
Light is produced from many natural and artificial sources. Controlling light and having an accurate understanding of its output, directionality and the appearance of what it irradiates is key to product development, quality and the success of a light source. Here are just a few examples of why Labsphere is leading the industry in light measurement.

Light Sources
The unique dual-output of equivalent beams make it a useful source for many comparative applications in addition to wavelength calibration and so on. The two output beams originate from two views of the single emitting spot where the electron beam from the single hairpin filament collides with the interchangeable anode.
