Light Guide Rod
A light guide rod is a high-tech product that reflects and diffuses source light through internal guiding material to distribute it uniformly. Used in lighting, signs, and vehicle lamps, it improves brightness and uniformity. Its main advantage is excellent light transmission. High-refractive-index materials such as acrylic or polycarbonate cause repeated internal reflections, reducing loss and conveying light from the source throughout the rod. Another feature is diffusion. Special internal structures, such as slightly convex or concave surfaces, scatter light uniformly. This spreads concentrated light to create a more even, softer effect. Besides lighting, guide rods are important in signage. Conventional signs often suffer uneven light and insufficient brightness. Guide rods improve propagation and distribution, making signs more noticeable and attractive. Automotive applications are also important. Headlights and taillights require high brightness and good distribution. Guide rods enhance transmission and diffusion to improve the driver's visual experience and safety. Overall, distinctive transmission and diffusion properties support lighting, signage, and vehicle lamps. Future technology should further improve transmission and uniformity, bringing convenience and comfort to life and work.

BIM-6203 deuterium-tungsten lamp light source Lamps Brolight
Wavelength Range: 230-2500 nm Bulb power - Deuterium lamp: 25W Bulb power - Tungsten lamp: 20W
The BIM-6203 deuterium-tungsten source combines highly stable deuterium and tungsten lamps. Innovative filtering suppresses characteristic deuterium peaks for highly stable, smooth, continuous output over 230-2500nm. It is well suited to high-precision quantitative absorbance, concentration, and transmittance measurements. The BIM-6203's two sources switch independently through housing buttons or individual remote TTL control.

Light-source device teaching experiment system SPT-EDU Lamps Cotest
Ketai distilled standard optoelectronics-industry source-testing methods into the SPT-EDU system for vocational-college and university optoelectronics students. At an acceptable cost, students learn and operate methods close to industrial practice. The basic version teaches LIV and parameters such as threshold current, operating current, and operating voltage. It expands to spectra, near-field optics, far-field optics, and other key parameters. Teachers can use these experiments to prompt reflection on influencing factors and further exploration. Within specified performance limits, it also supports university research testing for multipurpose use.
