Description
Continuous wave 488 nm (cyan) laser is widely used in fluorescence microscopy and flow cytometry. Such wavelength activates a number of different dyes, such as Alexa 488, eGFP, SYTO-13 DNA, Chromeo, just to name a few. Single-unit package is convenient both for end-user as well as for OEM applications. These lasers sources are available in 20 mW SLM and in 40 mW non-SLM options.

1 The optical power can be tuned from virtually 0% to 100%. However, other specifications, such as central wavelength, power stability, noise, polarization ratio, beam shape, quality and circularity are not guaranteed at power levels other than factory preset power. Significantly worse power stability is to be expected at very low power levels, e.g. <3% from specified nominal power.
2 The long term power test is carried out at constant laser body temperature (+/-0.1 ‎°C) using an optical power meter with an input bandwidth of 10 Hz. The actual measurement rate has a period of about 20 seconds to 1 minute.
3 The long term power test is carried out at constant laser body temperature (+/-0.1 ‎°C) using an optical power meter with an input bandwidth of 10 Hz. The actual measurement rate has a period of about 20 seconds to 1 minute.
4 Noise level is measured with a fast photodiode connected to an oscilloscope. The overall system bandwidth is from 2 kHz to 20 MHz.
5 For lasers without integrated optical isolators.
6 Break-out-boxes AM-C8 and AM-H10 can be used for conversion of UART communication to either USB or RS232.
7 TTL digital modulation up to 10 MHz.
8 Excluding control interface pins and an output window/fiber assembly.
9 Whichever occurs first. The laser has an integrated operational hours counter.
