Imaging pocket spectroscopes now available

We developed an imaging pocket spectroscope. It can be used for visualize the spectrum of light sources,  the rendering of colors or printed documents, or the absorption lines of minerals.

Additional to usual spectroscopes this imaging spectroscope can show the spectrum of particular areas. In can focus to infinity or any other closer distance.

The imaging optics can be disassembled for using as hand microscope. And the spectroscope can be used in the usual way. 

Diameter: 1,5 cm

Length:  7,8 cm

Weight: 18 g

The images show different spectra of florescence tubes. The images are taken trough a smart phone in a distance of approximately 4 m.

The spectral resolution is suitable to see the Fraunhofer lines in daylight spectrum.

The spectroscope is available with your individual laser engraving.

We sell small volumes via Ebay. Please contact us for higher volumes or for customized spectroscopes.

 

OLEDs – High Quality of Light

InnoVision finished a  project about „quality of light“. Therefore we measured different light sources. This results we are publishing now.

Fluorescence lambs have poor light because they emit light only in small spectral ranges (peaks in the spectrum) therefore the color appearance unter fluorescents lambs is changed. Experts say, the Color Rendering Index (CRI) is low. Light bulbs and halogen lambs have a brought spectrum, but they emit high intensity in infra red (IR) and have low intensity in the blue region. Therefor they are very inefficient and not good for work spaces where cold white (with more blue intensity) is preferable. LEDs and OLEDs emit light in a brought spectrum. Therefore the CRI is very good. Especially the OLED has no strong minimum in the spectrum. But the best light is a combination of OLED and LED
