Products/Services for measuring optical density
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. Search by Specification | Learn More
Density and specific gravity instruments are meters used to determine density and specific gravity. Search by Specification | Learn More
Measuring microscopes are used by toolmakers for measuring the properties of tools. These microscopes are often used for dimensional measurement with lower magnifying powers to allow for brighter, sharper images combined with a wide field of view. Search by Specification | Learn More
Densitometers measure the optical, photographic or area density of a material. They are used in a wide range of applications, from film processing to medical scans. Learn More
Opacity sensors and instruments measure the amount of light transmitted through a sample. Search by Specification | Learn More
...or a laser shield such as a stainless steel or lead shield. Laser protective eyewear must be specific to the type of laser radiation involved. Laser wavelength, optical density (OD), visual transmittance, peak irradiance, field of view, effects... Search by Specification | Learn More
Surface metrology equipment is used to measure the surface finish and/or geometry of engineering components. Surface texture and topology characteristics include surface roughness, contour, form, waviness and defects. Search by Specification | Learn More
Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources. Search by Specification | Learn More
Density test equipment is used to test the density of materials. Learn More
Coordinate measuring machines (CMMs) are mechanical systems designed to move a measuring probe to determine the coordinates of points on a work piece surface. Search by Specification | Learn More
Instruments such as quartz crystal microbalance (QCM) monitors, ellipsometers, RHEED systems, imaging stations, CD-SEMs, ion mills, C-V systems specifically designed for wafer metrology or in-situ monitoring of thin film parameters during thin film or semiconductors wafer processing. Search by Specification | Learn More
Optical time domain reflectometers (OTDR) measure the elapsed time and intensity of light reflected along an optical fiber. They are useful tools for locating problems in an optical network as they can compute the distance to breaks or attenuation Search by Specification | Learn More
...and instruments include specialized devices that measure thickness, thread size, pitch, serration, and other parameters. Height gages include micrometer, laser micrometer, and micrometer head gages. There are several gaging technologies for dimensional gages... Search by Specification | Learn More
Optical isolators are optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause feedback problems Search by Specification | Learn More
Optical spectrum analyzers (OSA) can divide a lightwave signal into its constituent wavelengths. This means that it is possible to see the spectral profile of the signal over a certain wavelength range. Search by Specification | Learn More
