Diffuse Optical Materials

The SphereOptics GmbH produces and offers the high performance plastic Zenith Polymer®. This sintered porous polymer is a proprietary form of Teflon and it can be used in various applications.

Due to its ideal Lambertian behavior and a diffuse reflectance value of 98% throughout the whole wavelength-range UV-VIS-NIR leads to a perfect reflectance reference (white reference) in the optical measurement area. In the last few years, either of the two companies have developed a range of reflectance standards as well as Integrating Spheres, both for industrial and medical measurement technologies. In addition, this material has been accepted as reference material in Space-projects.

Remote Sensing & Hyperspectral Imaging

As spectral data gains importance in a wide range of agricultural, geographical and industrial applications, there is a static increase for reliable and high performance devices. Analytical Spectral Devices, Inc., as one of the leading companies for portable VIS and NIR spectrometers, offer a series of high resolution spectrometers for laboratory usage, such as the LabSpec, or field and process usage, such as the FieldSpec3. The full range ASD spectrometers can cover the range of 350nm to 2500nm with a resolution of up to 3nm. (2nm@700m, 8.5nm@1400nm and 6.5nm@2100nm) Even radiometric measurements (W/nm*sr) with additional power information according to the wavelength can be obtained easily.

To correlate hyperspectral data, taken by imaging and non-imaging spectrometers, a reliable and sophisticated measurement system is needed. The company NEO offers a range of different spectral imaging sensors, the HySpex Series, all designed for airborne, field and laboratory measurements.

Sphere Based Measurement Technology

Since one century, the integrating sphere has been a reliable tool for measuring light output. Worldwide, this measurement method is accredited by national Institutes like NIST in the USA or PTB here in Germany. Over the past years the detectors and also the interior coating has been improved and nowadays there is a large variety of cooled and uncooled detectors for different wavelength ranges on the market.  The integrating sphere is classically used a light measurement system, where the source is either attached from the outside or placed inside the sphere. Another application is to use the sphere as a diffuse light generator with known output to calibrate detectors and cameras. SphereOptics, together with Labsphere provides the customer a broad range of different sphere sizes and configurations, dedicated for the customer's needs. All calibrations performed are either NIST or PTB tracable.
