Fast and Accurate Laser Safety Calculations with LaserSafe PC

LaserSafe PC Version 5.1

This is what LaserSafe PC software v5.1 can do for you

LaserSafe PC has become the one of the most widely used Laser Safety Calculation software programmes in the world. Version 5.1 is now released which includes all the amendments introduced in IEC / EN 60825-1: 2014, ANSI Z136.1-2014 with CDRH 21 CFR § 1040.10 Classification option.

Safety: Find out what is safe and what is not safe

Laser Safe PC v5.1 enables you to calculate the laser safety aspects of your laser system – quickly and easily.

Explore and experiment saving time

You can input different laser parameters experimentally to find out their effects and try out a large number of new scenarios to explore the safety of a laser setup or laser product. Save time and effort setting up and measuring the effects of lasers using this software instead of hardware.

Achieve more using High Speed Calculations

The speed and flexibility of the software enables calculations which, due to the constraints of time, are simply not possible by manual calculations.

Find which eyewear you need to keep you safe - quickly

Laser safety eyewear calculations are provided on the results screens, which give a wealth of information including all the correction factors in EN 60825, ANSI Z136, CDRH 21 CFR § 1040.10 and other laser safety eyewear information.

Identify the Class of laser you have

There is now a Classification screen which shows all the results necessary to assess a product classification based on the calculations.

New Interactive Assistant gets you going immediately

The new Interactive Assistant enables novices in laser safety to easily use the program to perform laser safety calculations and basic hazard assessments. The Assistant also acts as a tutor, enabling any user to learn and deepen their understanding of laser safety.

Free software upgrades for the first year

All software upgrades are free of charge for the first twelve months.

Why invest now?

New laser safety standard is now in use

  • LaserSafe PC 5.1 uses the standards EN 60825-1:2014 and ANSI Z 136.1-2014 – the latest and most up-to-date laser safety standards worldwide and CDRH 21 CFR § 1040.10. The introduction of this edition has had a major impact on the way pulse train calculations are carried out and on the classification process. LaserSafe PC v5.1 incorporates all changes in the standards and includes a new classification window to show the details of the calculations used in the classification process.
  • The LSPC "Assistant" is now interactive and allows navigation around features shown during the calculation and results display. Also, the saved calculation (.lsf) file format allows clicking on those files to launch the software.
  • The software is now also automatically updated from the Internet.
  • Save time and effort on laser equipment scenarios
  • Experiment more
  • Easy Standard change
  • Calculate results fast
  • Identify eyewear
  • Identify the Laser Class

Version 5.1

The New version 5.1 software has been updated to latest standards IEC/EN 60825-1:2014, ANSI Z136-2014, including CDRH 21 CFR § 1040.10 and latest safety eyewear specifications

Download free AEL / MPE calculation demo software.

Produced by GL Services in association with Lasermet Ltd, this is an ideal package for Laser Safety Officers or anyone else who regularly performs risk assessments on lasers. According with all the relevant standards, (see below), it will save you hours of work and give consistent and correct answers to your calculations of MPEs, AELs, accessible emission, optical density requirements, classification etc. Because it performs in seconds, calculations which used to take hours, you can easily explore the safety of different scenarios for your laser or laser system. LaserSafe PC is by far the most comprehensive and widely used laser safety software available, with extensive use by major companies, government institutions and Universities.
