On 16 November 2021 productronica will at last be opening its doors at the Exhibition Center in Munich – and we will be there to greet you!
After a long year and a half of digital events, we are looking forward to receiving you in person at our booth 315 in Hall B2.
Allow us to demonstrate the qualification of a display according to OEM specifications with our LumiTop 4000 and LumiSuite, and witness the ultrafast measurement of a CAS 125 in conjunction with an integrating sphere. In addition, on the subject of 2D measurement of VCSEL arrays, you will be able to observe a setup with our VTC series of IR cameras.
As a special highlight, we will be delivering interesting presentations on the measurement setups at our booth.
Secure your free ticket (please contact us via email) and visit us at booth B2.315.

Laser safety for 3D sensor applications

Instrument Systems has developed a practicable concept for safe laser viewing of VCSELs that satisfies the international laser safety standard. It is based on a laser class assessment chart and modular test system that is absolutely calibrated, and is supplied with a test certificate for the error budget.
The two main modules of the test system are the pulsed VCSEL tester PVT 100/110 and the camera-based VTC 2400. The PVT 100/110 is a special solution for the control and measurement of nanosecond pulses, as used for LiDAR or time-of-flight applications. Typical measurement parameters are wavelength, repetition frequency, pulse width, pulse energy and pulse sequence. The PVT 100/110 offers a high spectral resolution (≥ 0.12 nm), extremely short pulse sequences as low as 1 ns and up to 50A current, together with test pulse sequences with a repetition rate exceeding 100 MHz. The camera-based VTC 2400 enables analysis of the spatial radiation properties of complete VCSEL arrays in the far-field. Typical measurement parameters are average output, beam profile, highest intensity spot and angle of divergence (for the spot area).

Instrument Systems exhibited at C-Touch & Display in Shenzhen!

The annual trade fair C-Touch & Display was taking place in Shenzhen from 19–21 October 2021, attended by companies representing all production stages of the display industry. It features new products and technologies, among others from the touchscreen and display panel sectors, automotive electronics, consumer electronics and industrial controls. Instrument Systems was participating together with its distributor Giant Testing Equipment and presenting measurement solutions for flat panel display production lines, AR/VR displays and VCSEL technologies. We were exhibiting our LumiTop X20 suitable for low luminance tests, and our VTC cameras for VCSEL determination in the near- and far-field range.

Live calibration yields lively colors

Color and brightness are central to human visual perception and define the relevant criteria for quality control of any display. The human eye is extremely sensitive to color and brightness changes, and adapts easily to low and high light-intensity conditions. Consequently, high display uniformity of brightness and color is a prerequisite for a satisfying user experience. For quality control, most mass-produced displays are tested by imaging light-measurement devices (ILMD), usually employing calibrated complementary metal-oxide-semiconductors (CMOS) or charge-coupled device (CCD) sensors. With accurate calibration optimized to the device under test (DUT) and measurement conditions, ILMDs can measure and control luminance and color values with reference to human perception, as defined by the CIE 1931 standard.
