LumiCam 2400 - Outstanding accuracy, optimized for automotive display tests

 

As an imaging measurement system, the LumiCam 2400 captures the luminance and color distributions of screens or multifunction displays within seconds. It provides 5-megapixel images which present the spatially resolved measured values coded for luminance and chromaticity. The LumiCam 2400 models are perfect for versatile automotive test applications, e.g. measurement of luminance and color distributions of displays and control elements or uniformity analysis of flat panel display screens in car interiors.

Instrument Systems offers the LumiCam 2400 in three variants. The LumiCam 2400 Mono is a compact luminance camera with V(λ) filter for reliable and accurate luminance measurements. The LumiCam 2400 Color is equipped with three additional color filters for chromaticity measurements and is perfectly suited for broadband light sources. To achieve optimal measurement results for LED based test objects, the LumiCam 2400 Advanced features a total of six color filters and a patented matrix optimization algorithm. The 5-megapixel resolution of all models allows for convenient imaging and analysis of whole instrument clusters or small details with high resolution.

Powerful and user-friendly software

All LumiCam models come with a powerful software that calculates all relevant quantities as, e.g., the luminance Lv, the color coordinates x and y as well as color temperature, color uniformity or dominant wavelength.  Versatile analytical tools, such as spotmeter, polygon, line or 3D box, permit comprehensive evaluation of the measured data. The LumiCam software offers the possibility of false-color presentation for particularly impressive visualization of the values obtained.

INSTRUMENT SYSTEMS is continually working to develop and improve its products. Any technical changes, errors or misprints do not form grounds for compensation. The company’s terms of delivery and payment apply in all other respects. If not otherwise stated explicitly, all specifications refer to the Nikkor 50 mm objective with a 16 mm aperture.

4 Specification of LumiCam 2400 Advanced in the extended measurement range identical to the LumiCam 2400 Color (e.g. regarding accuracy of color coordinates).
5 Reference value for largest aperture opening (32 mm) and white LED. First measurement may take longer.
6 Extended measurement uncertainty (double standard deviation, k = 2).
7 Verified using a test set of color LEDs (peak wavelength between 449 nm and 640 nm) and white LEDs (3000 K to 5000 K); maximum deviation from measurement with reference
