Page 6: Laser Safety
Page 5 Laser Safety Wasatch Photonics X series Raman spectrometers with integrated lasers include a number of safety features to minimize risk of exposure and injury to the operator and any bystanders. Nevertheless, be aware that these remain Class 3B laser products and are therefore fundamentally unsafe for use without appropriate Personal Protective Equipment (PPE), such as laser goggles, and user training from a qualified instructor and syllabus. -

This can protect the optics from dust and damage when not in use, and represents an additional safety feature by physically preventing inadvertent laser emission when emplaced. For convenience, a magnetized clip is provided to hold the attenuator when not engaged. X series Operations Manual Oct 27, 2023... -
Page 8: Light-Tight Optical Bench
2.4. Light-Tight Optical Bench Wasatch Photonics Raman spectrometers are designed such that coherent laser light cannot escape the optical bench and radiate into the environment, save through the intended optical coupling (freespace front optic for ILP models, and FC/PC fiber connector for ILC models). -
Page 9: Laser Warning Leds
2.5. Laser Warning LEDs Wasatch Photonics Raman spectrometers with integrated lasers have two warning LEDs on the front panel. These LEDs are designed to be visible both from the front and top of the spectrometer. When operational, the LEDs will flash in synchronization; if either LED is illuminated “solid” (not flashing), that indicates a fault condition and the unit should be referred to the manufacturer for investigation and repair. -

2.8. Remote Laser Interlock Wasatch Photonics Raman spectrometers with integrated lasers include a remote laser interlock jack on the back face of the spectrometer (adjacent to the key-switch). This jack uses a standard stereo audio plug connector (SP-3540A, DigiKey 102-4779-ND), simplifying development of compatible plugs for your laboratory or OEM requirements. -

SMA-905 connector to collect Raman scatter from the sample. X series Raman spectrometer with ILC coupling Typically both fibers are joined in an external Raman probe like the Wasatch RP 785. It is important to use a probe built for the correct laser wavelength, as that determines the filter within the probe. -
Page 16: Ip (Integrated Probe)
Page 15 X series Raman spectrometer with IC coupling Besides having only the single SMA-905 fiber connector, these units are also visually distinguished by lacking any LEDs on the front face, as they have no integrated laser requiring warning signals. Likewise, the back face of these spectrometers lack other laser-safety interfaces such as the interlock key-switch or remote interlock socket. -
Page 17: Measurement Setup
However, Wasatch gratings and spectrometers are designed with low polarization dependence to ensure throughput remains consistent regardless of the input polarization state. Thus, as Raman scattering is inherently unpolarized, and given that it is a X series Operations Manual Oct 27, 2023... -

Note that the same probes can be used interchangeably between ƒ/1.3 and ƒ/1.8 ILC models, however, Wasatch Photonics RP series Raman probes are designed with an f/1.3 input aperture, and will thus match most efficiently with our f/1.3 spectrometer models. -

Page 46: Continuous Wave Pwm Vs "Pulsed
Continuous Wave PWM vs “Pulsed” When computing laser safety parameters, it is important to distinguish between Continuous Wave (CW) lasers and “pulsed” lasers. All Wasatch Photonics integrated lasers are Continuous Wave (CW) solid- state diode lasers. Pulsed lasers use an excitation medium which must be pulsed (pumped) at some rate to build up photons within a sealed resonance chamber, and then an optical switch (typically a Q-switch such as a Pockels cell) is used to briefly open the chamber and release the photons in a single high-energy pulse. -
