Raman Spectroscopy System
The PinPointer delivers a full-featured Raman spectroscopy system in a remarkably affordable, true handheld format. The lightweight unit is controlled by a pocket-sized computer and features easy-to-use RSIQ software for fast point-and-click operation.
An optional software add-on, RSIQ-QUAL provides one-touch identification of unknown substances by immediate
Conometer80
Easy to use and far more cost effective than traditional conoscopic systems, the CONOMETER 80 is ideal for measuring the viewing angle luminance, contrast and gamma (new!) of emissive displays such as LCD, plasma, OLED, FED and rear-projection displays. The system is well suited for use in QC, production process control and R&D.
By using Lumetrix's Electronic Bracketing, the system can measure from 0.0005 to 4,500 cd/m2 without the use of neutral density filters. Very high contrast ratios are measurable.
The simple optical design has fewer optical elements than competitive conoscopic (Fourier) lens configurations. The system is able to measure displays as small as 6mm wide. The simpler optical design also results in lower optical scattering (low stray light).
XR-Series Miniature Fiber Optics Spectrometers
The XR-Series of Extended Range Spectrometers from Ocean Optics are responsive across a wide spectral range, providing you an optical resolution of ~2.0 nm (FWHM) and the convenience of a single, monolithic spectrometer to cover all wavelengths from ~200-1050 nm.
The XR Option is now available for our USB2000+, Jaz-EL200 and USB4000 Spectrometers and in custom systems.
Specbos 1201 / 1201M in their basic configuration can measure Luminance only with diameters of 4 mm and
more. Therefore four focusing optics were developed to allow the measurement of spots with 3 mm, 1 mm, 0.5 mm and 0.25 mm diameter. These spots are marked by a laser circle. The 0.5 mm and the 0.25 mm add ons are fitted out with a magnifying glass to simplify the precise adjustment.
Measuring objects:
Alphanumerical and numerical displays
Fluorescent tubes with small diameter
Backilluminated signs
Other small light sources
The Lumetrix STiR 1.4 Spectrally Tunable Imaging Radiometer is a unique instrument: it delivers high performance spectroradiometric measurements from 400 nm to 720 nm in a 1400 x 1040 image. Radiance images at each wavelength are compiled and computed to report values at each pixel in the image such as CIE chromaticity, luminance, and radiance. The system's exceptional performance specifications include: low stray light, 1nm accuracy, a nominal bandpass resolution of 7nm, and more than six decades of dynamic range.
Measurement applications include the characterization of displays, LEDs and lamps.Users of spot spectroradiometers will appreciate the STiR for its speed and comprehensive measurement detail. The STiR offers the intuitive ability to superimpose measurement data on an image. Spectral data at every point in the image provides engineers with enhanced analysis not previously possible.
