They combine short pulse widths, high repetition rates, and high optical power in a compact and maintenance free set-up.<\/p>\n<p><strong>Direct emission in the ultraviolet<\/strong><br \/>\nLEDs from the PLS-I Series emit directly in the ultraviolet spectral range at wavelengths as short as 255 nm. Different LEDs with central wavelengths between 255 nm and 400 nm allow to choose a peak wavelength according to the needs of the application. Their spectral and timing characteristics are also particularly well-suited for biomedical applications, e.g., for the detection of labeled substances as well as naturally fluorescent amino acids like tryptophan or tyrosine.<\/p>\n<p><strong>Pulsed average power up to 300 \u00b5W<\/strong><br \/>\nThe LED heads from the PLS-I Series are designed to yield the maximum possible output power in pulsed and CW mode. In pulsed operation the maximum average optical power reaches typically 80 \u00b5W. In CW operation the average power reaches typically a few 100\u2019s \u00b5W and even up a few mW for wavelengths where the most powerful LEDs are available. The flexible Taiko architecture gives the possibility to work either in linear mode (constant pulse energy at any repetition rate) or in max power mode (max pulse energy at any repetition rate).<\/p>\n<p><strong>Pulse widths down to 1 ns<\/strong><br \/>\nThe pulsed LED heads of the PLS-I series emit nanosecond pulses with a full width at half maximum (FWHM) ranging from typ. 1 to 5 ns depending on the wavelength and on the power setting.<\/p>\n<p><strong>Suitable for time-resolved fluorescence spectroscopy<\/strong><br \/>\nThe PLS-I Series are very useful excitation sources notably for short range interactions as in a time-resolved fluorescence lifetime spectrometer, where sufficient power is required for wavelengths typically around 300 nm. In this range the PLS-I series offer a higher power alternative to the classic Sepia-compatible PLS series from PicoQuant with a factor 5 to 15 more in terms of optical power. On the other hand, the PLS-I series offers an affordable alternative to classic laser solution such as ultrafast laser with OPO or a VisUV from PicoQuant. All functions of the PLS-I Series such as repetition rate and output power are controlled and adjusted by the Taiko PDL M1.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>High Power Nanosecond Pulsed LEDs &nbsp; Features: Wavelengths from 245 to 600 nm Average power up to 300 \u00b5W (pulsed and CW) [&hellip;]<\/p>\n","protected":false},"featured_media":49323,"template":"","meta":{"_acf_changed":false,"footnotes":""},"product_brand":[],"product_cat":[109],"product_tag":[],"class_list":{"0":"post-49252","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-short-pulse-ns-ps-fs-lasers","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.6 (Yoast SEO v27.7) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>High Power Nanosecond Pulsed LEDs - Laser 2000<\/title>\n<meta name=\"description\" content=\"High power nanosecond pulsed LEDs.
