What are the main differences between the Optiprexx PLS and RubyLUX?

• The PLS is a stand-alone system whereas the RubyLUX may require a microscope (which we can supply as well) for operation;
• The PLS has a laser interlock system whereas the RubyLUX does not. This means that as a laser system the PLS is type I and the RubyLUX is type III. As such, to run the latter you need to have established laser precautions/procedures in place;
• The PLS is more ‘plug and play’ – one just needs to mount the DAC to the cell platform and perform the measurements. The RubyLUX may require some adjustment to the optics – especially if not supplied with the microscope of our choice;
• The Optiprexx PLS – Camera is an accessory to the Optiprexx PLS;
• Finally the RubyLUX has the option of a breadboard mounting including a DAC XYZ stage making this system then very similar to a PLS.

Laser Safety Classification of the Optiprexx PLS System

The Optiprexx PLS system is a precision optical setup that can be equipped with either a blue or green laser. In its standard configuration, this laser falls under Class IIIb, which includes continuous wave lasers with power outputs between 5 mW and 500 mW. Class IIIb lasers can pose hazards to the eyes and, in some cases, the skin upon direct or specular reflection exposure. Appropriate safety measures, such as controlled access and the use of protective eyewear, are typically required.

However, when the system is fitted with the Optiprexx PLS Interlock, the complete system is reclassified as a Class I laser product. According to international standards (IEC 60825-1), Class I lasers are inherently safe under normal operating conditions, meaning users are not exposed to hazardous levels of laser radiation during normal use.

This safety is achieved through engineered controls, such as beam enclosures, access interlocks, and failsafe mechanisms, integrated into the Optiprexx PLS Interlock. These features ensure that the laser beam is completely contained during operation, allowing safe use in standard laboratory environments without requiring additional laser-specific precautions.
