LED light source KeyLight™

ultravioletUVtunable

Product Overview
The Phoseon KeyLight OEM light source is a compact, modular UV-visible LED illumination module designed for integration into microscopy and fluorescence imaging instruments. It delivers precise, stable UV and visible output with low noise, low heat generation and long lifetime, enabling reproducible laboratory imaging and OEM system integration.

Key Details
KeyLight supports 4 to 7 independently switchable channels across UV, visible and near-infrared wavelengths. Available models include KL400, KL500, KL600 and KL700, with configurable wavelengths and optical outputs to match dyes and imaging techniques used in molecular and cell biology.
