Neutral Density Filters & Dark Mirrors Neutral Density Filters and Dark Mirrors. There are some applications for which the light used is too intense. In those cases a filter is often needed to apply a reduction in the intensity of the light without influencing the spectral profile. These wavelength neutral filters are often specified in terms of their optical density. Optical density can be calculated by taking the negative of the log (base 10) of the transmittance. For example, an optical density of 0.5 would be equivalent... (read more)
Neutral Density Filters Neutral density filters are useful in a number of applications such as attenuators for broadband spectral sources, partial reflectors for light balancing applications and for use as neutral beamsplitters. Metallic type neutral density filters obtain their optical density by depositing a metal alloy coating onto a specific type of substrate which is determined by the wavelength region of interest. Absorbing ND filters are produced using Schott NG glass, and rely strictly on the absorptive... (read more)Browse Neutral Density Filters Datasheets for Andover Corporation
Gurley Precision Instruments
Neutral Density Filters Neutral Denisty Filters from Gurley are reflective type filters which attenuate light from 0.04 to 4.0 optical density. Available for various wavelength regions to maximum attenuation, customers can select from 400nm to 750nm, 400nm to 1200nm and 400nm to 2000nm. Standard dimensions include 12.7mm and 25.4mm outer diameters, made from B270 glass material and 1.00mm thick. We guarantee the surface quality to 40-20.

Expanded Selection of IR Neutral Density Filters Andover's Infrared Neutral Density (ND) filters are spectrally flat from 2-14 µm. They are comprised of metallic coatings on high-quality Germanium substrates. Metallic-coated ND filters obtain their optical density from a metal alloy coating on a substrate determined by the wavelength region of interest. Unlike the all-dielectric or absorption type, the metallic type ND filter employs a combination of absorption and reflection to reduce the intensity of light. Andover has recently added...

SCHAEFER Inc. (Power Quality Group – Harmonic Filters)
Active Harmonic Filter The PB-SERIES is an active harmonic filter system for tower buildings as well as automation, windturbine and various other industrial applications eliminating harmonic oscillations and consequently costs for reactive energy. The filter monitors the current signal and compensates for the unwanted elements of the measured current. Thus, the filter ensures a harmonic suppression independently of the number of loads. Furthermore the filter corrects the power factor, improving the systems... (read more)Browse Harmonic Filters Datasheets for SCHAEFER Inc. (Power Quality Group – Harmonic Filters)
RF Dust Control Filter materials. Dust from wood, grain, glass, clay, coal & carbon black. Metallurgical fumes. Abrasive materials like glass cullet, taconite & soda ash. Sticky substances like sugar or starch. RF filter can cut power costs by as much as 75%. The cleaning system of this efficient filter is powered by an air pump rather than the conventional fan. The result is the RF filter demands only 25% of the power needed by similar filters. Of course, the RF filter cuts more than power costs. It goes... (read more)
