Electro-Optical Products Corp.
An external clock signal, to provide an ultra stable modulating optical beam motion [sub] system. The system can be used as a "stand alone" unit, in the laboratory, or can be incorporated into a larger instrument/system. The chopper is ONE FIXED FREQUENCY, picked from the range of 5 Hz to 20 kHz. The chopper is a small size, light weigh, low cost and long life device. It requires low power drive electronics and does not radiate electromagnetic interference (EMI). It has high frequency stability and high amplitude stability. The chopper is IR, VIS and UV and high vacuum capable. Reference signal and position output available.
-
McPherson, Inc.
Reflective condensing system and focusing accessory for coupling light sources to monochromators. It uses two mirrors to focus to the entrance slit. The reflective system eliminates chromatic aberration, provides maximum spectral range, and does not require refocusing. Accessories like light choppers and filter wheels can also fit inside next to the slit. Versions with rotatable mirror available for up to four source direction.

Model 775 -
SIMCO-ION, Technology Group
The pocket-sized Simco-Ion Model 775 Handheld Electrostatic Fieldmeter is designed to locate and measure static charge potentials on product, people, equipment and packaging. The Model 775 Fieldmeter uses a non-contacting, chopper stabilized field sensor and a ranging light mechanism to ensure correct measurements of electrostatic fields in all areas—even those using air ionization.
