Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors

Optical bandpass filters are designed to transmit a specific waveband.  They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light

Neutral density filters are designed to reduce transmission evenly across a portion of the spectrum. They are slightly sensitive to angles but they are much more forgiving than interference filters.

PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies.

Charge converters and charge amplifiers convert the charge output from a piezoelectric, capacitive or other charge-producing sensor to a signal such as analog voltage or current.

Bridge conditioners are instruments that provide excitation and support for strain gages, Wheatstone bridges, load cells, and sensors. They also include circuitry for signal conditioning, amplification, and processing.

RF attenuators are circuits that reduce the power level of a signal by a certain amount (gain), with little or no reflection. They reduce the output signal with respect to the input and measure the power reduction in decibels (dB).  

Variable reluctance linear position sensors and switches are noncontact devices that use variable reluctance based technology, and whose output signal represents the distance between an object and a reference point

Optical and light microscopes use the visible or near-visible portion of the electromagnetic spectrum to magnify images of objects

RF waveguide attenuators are used to reduce the power level of a signal by a certain amount (gain), with little or no reflections. The output signal is reduced with respect to the input

Optical manufacturing services design, fabricate, finish and test optical components and optical elements

Optical choppers are mechanical or electronic devices that pass and then interrupt a beam of light for a known brief interval.  Optical shutters are used to control the amount of time that a light sensitive material is exposed to radiation. 

Variable transmissions are used in industrial applications to alter the speed of an output shaft

Linear position sensors, all types, is a general search form for all linear position / displacement detection product areas.

Optical materials consist of glasses, plastics, ceramics and coatings with reflectivity, opacity, color or other properties tailored for mirror, lens, laser or other optics applications
