LBTEK Semiconductor Lasers are composed of imported original laser diodes and adjustable driving power supplies, featuring a compact and small-sized design. They boast high output power stability, long service life, and continuously adjustable output power, making them easy to operate and capable of prolonged continuous operation. With reliable performance, the power supply includes built-in overheating and current-limiting protection circuits (with fuse included). These lasers can be applied in fields such as DNA sequencing, flow cytometry, digital imaging, analytical chemistry, particle measurement, laser confocal microscopy, and Raman spectroscopy, making them an excellent choice for optical system design, integration, and end-user R&D. The lasers come with a collimator and can output fixed modes at central wavelengths of 405 nm, 488 nm, 532 nm, 635 nm, 780 nm, 850 nm, 980 nm, and 1550 nm. LBTEK Semiconductor Lasers are accompanied by detailed user manuals and test reports, and custom laser services are also available, including customization of different wavelengths and output power specifications. For specific customization needs, please contact LBTEK Technical Support. When using lasers, even at very low power, they can still easily cause harm to the user's eyes. It is recommended that users adhere to safety guidelines and wear protective equipment during operation.
