The web-based Evaluator has proven itself as an integral tool for Laser Safety Officers (LSOs) in the field with its accessibility, easy navigation, and accurate results. In January 2016, LIA unveiled an alternative platform of this innovative program: The Desktop Evaluator.
Unlike the web-based system, the Desktop Evaluator is delivered via a digital download, from which users can install the program to their computer. As a software program stored on the computer, the Desktop Evaluator eliminates the need for internet access.
Similar to the web-based version, the Desktop Evaluator performs several repeated calculations based on the ANSI Z136.1-2022 American National Standard for Safe Use of Lasers, including maximum permissible exposure (MPE), optical density (OD), nominal ocular hazard distance (NOHD), nominal hazard zone (NHZ) and laser hazard classification.
Both versions of the Evaluator offer users an easy and seamless experience, assisting LSOs of all skill levels to complete necessary safety calculations in the field. For instance, both versions allow effortless switching of laser settings between CW, Single Pulse, or repetitively pulsed lasers, in addition to adjusting the beam profile (circular, elliptical, or rectangular). Now companies can choose the format that best meets their specific needs. Compatible with Windows 10+ PDF viewer, the easily downloadable program – which most closely resembles the web-based version’s advanced subscription level – lives on your computer, offering constant, uninterrupted access.
Additional Desktop Evaluator Benefits:
Military users, whose firewalls often restrict continuous access to online content, will now be able to perform calculations without fear of losing connection
A simple layout allows users to input variables – including wavelength, energy/power, pulse width, PRF, focal length, limiting aperture and more – on the screen’s left-side panel, while final output appears on the right-side panel
Intermediate calculations are also shown to further verify hand calculations
The classification of the laser is displayed in the Hazard tab for eye and skin
Values for MPE, NOHD, NHZ, OD, Specular NHZ and Diffuse NHZ are provided for both eye and skin
Users can print reports or save the information to a file for later review
A User Guide, located in the Help menu provides an overview of the program, from the explanation of how to perform an evaluation to parameter descriptions and calculated results. Additionally, you can double-click any input parameters for an instant definition.
System Requirements:
Windows 10+
PDF viewer (such as Adobe Acrobat or Adobe Viewer)
Please note:
This is a single-user version.
Installation key will expire 90 days from the day of purchase.
Compare Evaluator Editions
Both web and desktop formats of The Evaluator offer users an easy and seamless experience, assisting Laser Safety Officers (LSOs) of all skill levels in completing necessary safety calculations. Both versions allow effortless switching of laser settings between continuous wave (CW), single pulse, or repetitively pulsed lasers, as well as the ability to adjust the beam profile (circular, elliptical, or rectangular).
Now companies have the flexibility to choose the format that best meets their specific needs.
Specially designed for users with minimal experience, the Basic package provides essential and fundamental laser hazard calculations in an easy and simple format.

Minimum Optical Density (OD)
Nominal Ocular Hazard Distance (NOHD)
Classification
Eye Experiments
Our most popular subscription level, the single-user Intermediate package provides the best solution for industrial applications and organizations where laser safety calculations are needed for skin and eye hazards. We recommend the Intermediate level for industrial manufacturing facilities, job shops, auto industry, and organizations that process metals.
When upgrading to Intermediate from the Basic package, the additional features include elliptical, rectangular, and tophat profiles, focused beams, classification, exposure time, MPE skin, reflections, laser barriers, and reports.
Features of the Intermediate package include:
All Basic Features, plus...
MPE Skin
Intrabeam NHZ (Skin)
Elliptical, Rectangular, and TopHat Profiles
Focused Beams
Exposure Time
Skin Experiments
Reports
Perfect for the professional Laser Safety Officer (LSO), the Advanced edition provides more comprehensive and detailed features for performing sophisticated laser calculations. It is a must-have for experienced and highly skilled LSOs working in research facilities, government, military, and advanced laboratories.
Professional-level LSOs will appreciate this edition's more advanced features including source size, laser database, range, aided viewing, atmospheric attenuation, limiting aperture, Optical Density (OD) at Range, and graphs.
Features of the Advanced include:
All Basic & Intermediate Features, plus...
Range
Aided Viewing
Atmospheric Attenuation
Limiting Aperture
OD at Range
NHZ Diffuse Reflections
NHZ Specular Reflections
Laser Barriers
Laser Database
Source Size
Unlike the web-based system, the Desktop edition is delivered via digital download (link to the installer is provided after purchase), allowing the user to install The Evaluator on a local computer.
Similar to the web-based version, the Desktop Evaluator performs several calculations based on the ANSI Z136.1 American National Standard for Safe Use of Lasers, including maximum permissible exposure (MPE), optical density (OD), nominal ocular hazard distance (NOHD), nominal hazard zone (NHZ), and laser hazard classification.
System Requirements:
Microsoft Windows 10/11
Adobe PDF (Acrobat or Viewer)
You can easily upgrade or downgrade to any subscription level at any time — making it a flexible and scalable solution for dynamic organizations.
