TFCT25

Product catalog summary

Description
The TFCT25 is a test system designed for measuring the optical transmission of lateral light-emitting light guides, commonly used in automotive lighting. It ensures uniform light emission and checks for issues like yellowing of plastics, which can affect color temperature.

Specifications
The system includes a CIE 127 conform integrating sphere spectroradiometer, a precision power supply for LEDs, and user software. It measures luminous flux, spectrum, color, and color shift of LEDs, with a spectral range of 350 nm to 1050 nm.

Components
The system features the BTS2048-VL light meter and the ISD-25-V01 integrating sphere, which together meet CIE 127 requirements for LED measurement. The LPS-20 power supply supports constant and pulsed current modes.

Software
The S-BTS2048 user software facilitates operation and data analysis, including PASS/FAIL tests. A Software Development Kit (SDK) is available for system integration.

Calibration
The system is factory calibrated, traceable to PTB standards, and includes a calibration certificate. Calibration is performed using the BN-LHSF-2P-20 lamp.

Applications
Primarily used for quality assurance in the production of light guides and inspection of LEDs, the TFCT25 is suitable for both production and incoming product inspection.

Purchasing Information
Article number 15305427 refers to the TFCT25 measurement system. An optional set of exchangeable apertures (15305433) is available for custom measurements.

Description TFCT25 test system for lateral light-emitting light guides Lateral light-emitting light guides are now widely used in the automotive industry for daytime running lights, tail lights and brake lights. Their aesthetic design and 3D shape are significant recognition factors. They are made of plastic and have a very complex lateral structure which is designed to ensure uniform light emission along the entire length. Among the numerous test criteria in the manufacturing process are dimensional stability, homogeneity, and intensity of the lateral radiation. The measurement of the spectral...

The system comes with the S-BTS2048 user software for the operation of the TFCT25 test station. The software has an enhanced tool for easy data analysis as well as integrated PASS/FAIL tests. Sample holders for attachment of different samples/light guides The test system is supplied with sample holders (3 for left- and right-handed light guides respectively) for positioning of the light guides, which often have a 3D shape. These can be moved and fixed freely on the test bench thanks to the magnetic tabletop. The height-adjustable sample holders have an articulated arm and clamping jaw with high...
