Description
445 nm laser diode module is an excellent choice for flow cytometry, fluorescence and biomedical applications. Small footprint, stable power, low power consuption are only a few advantages of this laser. Single-mode fiber provides practically ideal beam quality and focusability, thus making this laser an ideal solution for high-resolution fluorescence imaging and other applications.

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 Break-out-boxes AM-C8 and AM-H10 can be used for conversion of UART communication to either USB or RS232.
6 TTL digital modulation up to 10 MHz.
7 Excluding control interface pins and an output window/fiber assembly.
8 Whichever occurs first. The laser has an integrated operational hours counter.
