The LS-450 blue pulsed light source is an LED that produces pulsed or continuous output at 470 nm -- blue region - for fluorescence measurement. This light source is designed to be used with Ocean Optics spectrometers for fluorescence measurement, with the FOXY fiber optic oxygen sensor, and sampling optics such as the CUV-UV-ALL 4-way cuvette holder. The LS-450 controls the lamp on/off by manual or software operation, for pulsed or continuous mode. It can also be used together with the LS-450 for other special LED wavelengths (see below). The LS-450 connects to the spectrometer through an interface cable, using an SMA905 connector. You can configure the operating power through the jumper module on the circuit board of the light source or the S2000 spectrometer. Also available is the LS-475 pulsed blue LED, characterized by its wavelength and fan cooling (475 nm). The R-LS-450 blue LED is the rack-mount version of the LS-450. For multiple LED users with limited desktop or rack space, the R-LS-450-2 (2 LEDs) rack-mount version is another option. You can configure the operation of the R-LS-450 and R-LS-450-2 through the module on the R-LS-450 circuit board. In addition, the LS-450 can be installed on the SF2000 spectrometer. The LS-450 is mounted on a card, in the same box as the spectrometer. Through the 10-pin connector of the spectrometer, the USB-LS-450 module connects with the USB2000 spectrometer. The spectrometer provides LED power and also ensures the same functionality and I2C communication. By adding a sampling optical element and an interface connected to a laptop computer, the SB2000-with-USB-LS-450 provides a convenient, portable system. The USB-LS-450 has a built-in 24-bit analog-to-digital converter, forming a 100 ohm platinum RTD. The USB-LS-450 can store temperature and oxygen calibration coefficients.
