Fiber Coupled LED

375nm to 940nm Multimode wavelength LED are designed for microscopy and other applications that require multiple color channels.The LED current of each channel can be adjusted independently or modulated via an external voltage.The multi-wavelength LED system offer a compact housing with a backlit, easy-to-read LCD display. They are operated via the buttons on the front panel.

Features
â–  UV, Visible, and NIR Versions (from 375nm to 1550nm)
â–  The SMA connector is ideal for multimode fiber.
â–  Multi-wavelength fiber coupled LED available.
