Lumencor's SPECTRA X Light Engine is an illuminator used in fluorescence microscopy that is recognised for its optical-breadboard-like versatility, its ease of control over excitation spectra, and its short- and long-term power stability.The product's spectral output and flexibility make it particularly suitable for fluorescence microscopy and multiplex immunohistochemistry (IHC), a technique used to simultaneously detect multiple markers within a single sample. When combined with multiplex IHC, the device enables researchers to gain a more detailed and comprehensive understanding of tissues and cellular environments.The latest version of the product maintains its user-exchangeable bandpass filters while introducing several improvements. It features an increased spectral range with solid-state LED light sources, enhancing compatibility with bandpass filters and fluorophores. New excitation windows at 365 and 660 nm are included, while filtered output power is 100-700 mW for each of the six solid-state light sources (previously 50-500 mW).The design now covers the entire spectrum from 365 to 750 nm, with teal and near-infrared light sources included as standard. The linear output power-to-intensity control setting relationship for all six solid-state light sources is designed to be highly precise, while interlocks provide user safety and mitigate the risk of inadvertent light exposure.
