Capable of performing quantitation and purity checking of nucleic acids, quantitation of proteins, and photometric measurements (OD values displayed and printed for specified wavelengths, up to 8 wavelengths). Simply drop 1 to 2 μL of the sample onto the measurement window and press the instrument's Start button (or click the Start Measurement button in the software window), and all steps in the process, from setting the optical path length, measurement, up until the task of wiping off the sample from the measurement window, are all carried out automatically. Troublesome work of moving arm up and down and wiping the sample from the measurement window now unnecessary. Moreover, when using the specialized software, all it takes to perform a measurement, output a report, export data, or carry out other common tasks is to click buttons on the toolbar.

Lisun Electronics Inc.
LPCE-2 is an Integrating Sphere Spectroradiometer LED Testing System for identifying the performance of single LEDs and LED lamps. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters. According to CIE127-1997, IES LM-79-08 and IES LM-80-08, it recommends to using an array spectroradiometer with integrating sphere to test SSL products. The LPCE-2 system is applied with a CCD Spectroradiometer (LMS-9000B or LMS-9000A) and worked with A molding integrating sphere with testing holder base function which will be more circle and the test results will be more accurate than the traditional integrating sphere.

Shenzhen Chuangxin Instruments Co., Ltd.
LCG-1600 Goniophotometrc System carries out measuring methods of fixed location and rotating luminaires. The measured luminaire is installed on the two-dimension rotating table, using “+” laser to make the luminaire lighting center superposed with the rotating center of rotating table. The mechanical equipment allows turning the tested luminaires around a vertical axis and a horizontal axis. When tested luminaires turn around horizontal axis, the detector which is at the same level with rotating table will measure the intensity of each direction at this surface. When rotating with vertical axis, the detector will measure the intensity at the vertical surface. The vertical and horizontal axis can be rotated continuously at ±180° or 0~360°. According to the measurement requirements, the system can be operated in C-γ coordinates. When getting intensity distribution data, computer will calculate other photometric parameters automatically.

The photometric specifications of LEDs must meet very high tolerance requirements regardless of whether they are to be used in general, automotive or other specialist lighting applications. This is often a problem since the manufacturing tolerances of LEDs can be higher than those permitted in the end-use applications. Also, LED binning by LED manufacturers in order to classify LEDs based on their tolerances is performed with flash mode testing using pulsed current flow. However, end-use applications of the LEDs often operate in constant current mode and with significant thermal effects. The sophisticated LED processing industry therefore requires measurement devices that can be used for both manufacturer-compliant pulsed mode, as well as constant current operation mode. When the LEDs are run in constant current mode, the junction temperature has significant influence on the performance and lifetime of the LED. Therefore, test systems should be able to test the LEDs at specific junction temperatures.

To measure light radiation’s spectral characteristics, Instrument Systems optical spectroradiometers are the instruments of choice. Instrument Systems has a variety of optical spectroradiometers to meet any user’s needs or budget. Instrument Systems Spectrometers mainly measure UV-VIS spectroradiometry, luminous flux, LED production and LED radiation levels. More importantly, they provide these measurements at a fast rate, gathering data very quickly and efficiently. A number of models come with innovative features that allow the systems to be used universally in a broad range of applications and functions. These systems conveniently change into spectroradiometers when users attach absolute calibration and optical probes. It’s critical that these units maintain a high degree of accuracy and quality in order to return precise calculations of colorimetric, photometric and radiometric data through the built-in software. For these and other reasons, Instrument Systems continues to expand the leading edge of technology by committing the majority of its Research & Development work to this field.
