GL Optic Announces World’s First Smart Spectrometer for Reliable Measurement of LED Luminous Flux

The Android-based GL SPECTIS 1.0 touch spectrometer from GL Optic is an innovative spectral instrument featuring intuitive operation for mobile light measurement in the visible spectrum. In addition to the many performance features of previous models, the GL SPECTIS 1.0 touch also measures luminous flux (lumen) from LEDs and other light sources.

With its extended functionality, the instrument is a valuable tool for light designers and lighting product manufacturers. The light output of LEDs is typically listed as luminous flux (lumen). The GL SPECTIS 1.0 touch in combination with the GL OPTI SPHERE 48 mini integrating sphere can be used for luminous flux measurement of individual LEDs and with the standard diffusor can also used for distance-dependent illuminance measurement of LED lamps. The spectrometer is a highly useful instrument for the entire lighting product manufacturing process.

The GL SPECTIS 1.0 touch is the ultimate tool for measuring, analyzing and storing key parametric data using the integrated touch display (240x320 pixels). Data needed for LED qualification includes the color rendering index (CRI) in accordance with the CIE standards, correlated color temperature (CCT) in accordance with the CIE standards, color coordinates in accordance with CIE 1931 and CIE 1964 as well as the radiant power value (mW) and luminous flux. The handy instrument has a spectral range of 340 - 750 nm. The physical resolution is ~ 1.7 nm with a wavelength reproducibility of 0.5 nm. The convenient, user-friendly instrument includes everything needed for high-precision calculation of colorimetric data. High sensitivity and innovative noise suppression are key features which make it possible to obtain reliable measurements at low signal strengths. Innovative technology limits the measurement uncertainty of the color coordinates (x/y) to 0.0015, putting the spectrometer on a par with complex, expensive lab instruments.

GL OPTIC performs spectral calibration on all of its spectrometers prior to shipment. The standard diffusor is cosine-corrected and calibrated for measuring the illuminance and irradiance of light sources.

The instrument is also calibrated in combination with the handy GL OPTI SPHERE 48 integrating sphere for luminous flux measurement.  With the aid of an intelligent coding system, it detects the optical probe and automatically selects the appropriate calibration, virtually eliminating the risk of measurement errors.

The instrument features Android operating system architecture and state-of-the-art connectivity including WiFi and Bluetooth. An SD card slot and USB 2.0 port enable the spectrometer to interact with PCs and notebooks. The handy, mobile instrument features a compact design (74 mm x 146 mm x 24 mm) and weighs only 315 g. Many accessories including optical probes and integrating spheres are available in a range of sizes.

The optional GL SPECTRO SOFT software provides all of the functionality needed for lab use or production. It can be used to control the spectrometer, the portfolio of peripherals and external integrating spheres. It also offers various data acquisition functions, multiple numeric and graphic display options for visualization of the measurement results and a number of export options. Users can perform spectral analyses and save the measurement results on a PC via the built-in USB port.
