Testing & Detection
Due to the unique and varying needs of different applications, Edmund Optics offers a wide variety of
optical testing and detection products. These instruments and devices are designed for a range of uses,
from the measurement of light to the maintenance of optical components.
Scratch-Dig Standards: Page 437
Scratch-dig standards are used to quantify and rate the quality of an optical
surface. Scratches are long, thin imperfections in the surface. Digs
are typically a small spot or a pit in the surface. A typical scratch-dig
number is specified as 10-5 (for high quality surface) to 80-50 (lower quality
surface). Edmund Optics offers precision sets and standards that are

Testing/Alignment: Pages 434-438
A Spherometer is used for measuring the radius of curvature for convex
and concave surfaces. We offer a kit with seven standards capable of
measuring surface radii from 2,5 mm - 1.000 mm. Abbe refractometers
can be used to measure the refractive index of any transparent or translucent
material. Autocollimators are optical instruments useful for noncontact
measurement of small deflections and vibrations, and can be
used to determine parallelism or perpendicularity between two surfaces,
angular error of prism angles, or straightness of movement.
Spectrometers: Pages 447-448
A spectrometer is a compact instrument that measures the spectral content
of light. They can be used to characterize the absorption, reflection,
and transmission characteristics of materials as a function wavelength.
Each spectrometer ships with a powerful and intuitive software interface
capable of performing a variety of functions such as spectrum smoothing,
background removal, color analysis, and configurable spectral acquisition.
Detectors: Pages 450-452
Silicon and InGaAs Detectors and Avalanche Photodiodes detect light intensity
through the photovoltaic effect, transforming light energy into an
electrical current. Photodiode Receiver Modules combine these sensitive
detectors with pre-amplifier electronics for detecting VIS, UV, and NIR
wavelength ranges. For signal detection requiring the highest sensitivity,
bandwidth or gain, we offer Photomultiplier Tube (PMT) modules.
Amplifiers: Page 451
Transimpedence Amplifiers convert and multiply the small currents produced
by photodetectors to larger usable voltages, facilitating the detection
of small amounts of light. They are used in a range of electro-optic
applications for the laboratory as well as OEM integration.
