Представлены лазерные флуорометры, способные регистрировать сигналы люминесценции с наносекундным временным разрешением. Универсальный флуорометр позволяет работать в широком спектральном диапазоне с разрешением вплоть до десятых долей нанометра. Специализированный флуорометр для измерения свечения синглетного кислорода in vitro и in vivo обладает уникальной чувствительностью в ближней инфракрасной области. Приведены экспериментальные результаты, подтверждающие высокие технические возможности установок.

Laser spectrometers for registration of luminescent signals with nanosecond temporal resolution are presented. The versatile spectrometer is capable to operate with up to tenth of nanometer resolution in wide spectral range. The specialized spectrometer for singlet oxygen luminescence measuring in vitro and in vivo possesses unique sensitivity in the near infrared region. Experimental results confirming high technical capacities of the setups are presented.
