Knight+ Series Picosecond deep-UV 266 nm Laser Knight-DUV-3
The Knight+ series industrial picosecond 266nm laser uses a compact integrated design and an upgraded control system for improved power stability and consistent optical performance. A proprietary picosecond fiber seed source, free-space solid-state amplification and efficient frequency conversion produce high-repetition-rate picosecond deep-ultraviolet pulses. Real-time multiphysics data monitoring and recording support remote diagnosis and predictive maintenance. Performance is benchmarked against comparable imported products. The Knight+ picosecond deep-ultraviolet laser supports custom dimensions and optical parameters, with output up to 10W and pulse frequency of 60MHz-120MHz, for semiconductor wafer-defect inspection in advanced processes.

300X100 Air Cooling UVLED Light Source
UV Light Systems
Szlamplic
The 300X100 air-cooled UVLED source directly generates UV using high-power LED chips proportionally integrated with emission from 200nm to 450nm, producing a selected peak wavelength in that range. Conventional curing machines appear bright and hot because their broad spectra include only a fraction useful for curing, with much visible stray light and heat that can damage eyes and deform workpieces. This UVLED area source emits high-purity monochromatic 365nm light as a cold source. Workpiece temperature rises only about 3 degrees without deformation. Energy is concentrated in the useful curing band, giving practical results comparable to a high-pressure mercury lamp with stated intensity 1000-2000MW. Edge-to-center irradiation variation is ≤3%, providing excellent uniformity.

UV LED Light Source Curing Lamp for Gravure Printing LPF24012
UV Light Systems
Szlamplic
Weight: 4.2 kg Dimensions: 244 mm × 130 mm × 250 mm Lighting Window: 240 mm × 12 mm
LAMPLIC's 3 gravure UV LED curing-source series use standard COB UV LED modules, DC-DC controls and aviation connectors. Controls include PLC 0~24V, 0~10V analog energy adjustment, ON/OFF, and optional 485, 232 or PWM. The 4 wavelength options are 365, 385, 395 and 405. Since 2016, LAMPLIC has researched UV LED gravure processing. Gravure's outstanding speed and quality have created a large global installed base, but traditional solvent inks cause severe air pollution, with VOCs exceeding 70% of ink use. The 100%-solids UV LED solution prints above 200m/minute with zero VOC emissions, addressing pollution at its source. Patented packaging/drive technology delivers irradiance of 40W/cm2 with high stability and reliability. The 3 series cover applications from small gravure-printed vest bags to high-speed flexible-packaging films, providing a new solution for gravure VOC control.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
The 850 nm and 940 nm infrared narrow‑bandpass filters launched by Innovation Photoelectric are core optical components specially designed for day‑and‑night security cameras. They effectively eliminate image interference during visible‑light and infrared‑illumination switching, delivering stable round‑the‑clock monitoring performance.
Within cutting‑edge ultrafast photonics research, asynchronous optical sampling (ASOPS) and synchronous sampling serve as fundamental technologies for terahertz excitation detection, coherent Raman imaging and other time‑resolved spectroscopy experiments.
